What to Know About Drug Addiction? Definition, Causes, Effects, and Treatment

Drug addiction is a condition where an individual increasingly relies on substances such as drugs or alcohol, leading to significant disruptions in their ability to manage everyday responsibilities and relationships. This reliance often manifests as a compulsive behavior that overshadows other aspects of life, ultimately hindering personal and social well-being.

Addiction to drugs arises from a combination of factors, including genetic predisposition, environmental influences, and social pressures. Some individuals are more susceptible to developing an addiction due to their genetic makeup, which makes them more vulnerable to the effects of drugs. Additionally, the environment in which a person grows up, such as family dynamics, childhood experiences, and peer relationships, affect their likelihood of engaging in drug use and potentially becoming addicted. Social pressures, such as the normalization of drug use in certain social circles or the desire to fit in, can also lead individuals down the path of addiction.

Prolonged drug consumption results in physical ailments, including organ impairment, heightened susceptibility to infectious diseases, and neurological alterations that affect judgment and conduct. There are also social and psychological effects that have long-lasting consequences. Substance abuse often leads to strained relationships with family and friends, as well as difficulty maintaining employment or financial stability.

The National Institute on Drug Addiction 2011, suggests that treating drug addiction should involve medical intervention, counseling, and support to help individuals overcome their addiction. It includes detoxification to rid the body of drugs, therapy to address underlying issues, and support groups to aid in recovery.

What is Drug Addiction?

Drug addiction is a chronic disease characterized by the compulsive use of substances despite harmful consequences, according to Fluyau D, Hashmi MF, and Charlton TE. Drug Addiction: StatPearls Publishing Journal; 2024.

The National Institute on Drug Abuse (NIDA) suggests that addiction disrupts the brain’s reward system, leading to intense cravings and a loss of control over substance use. 

Approximately 21 million Americans have at least one addiction. Yet, only 10% receive treatment, as reviewed by the ABC News article titled, “Nearly 21 Million in US Have Substance Use Disorder: Surgeon General’s Report” (November 2017).

Addiction alters the brain’s reward system, particularly affecting the neurotransmitter dopamine. Initially, drug use can produce intense feelings of pleasure, but over time, the brain adjusts to the excess dopamine, leading to tolerance. This often results in users taking more significant amounts of the drug to achieve the same effect, further reinforcing the addictive behavior. 

The brain changes associated with addiction are long-lasting, making addiction a relapsing disease where individuals in recovery remain at risk for returning to drug use, even after extended periods of abstinence.

What is the Difference Between Drug Abuse vs. Addiction?

The main difference between drug abuse and addiction is that drug abuse refers to the harmful use of substances without the presence of physical or psychological dependence, according to the American Psychological Association on “Substance use, abuse, and addiction.”  In contrast, addiction is characterized by an inability to stop using drugs despite the negative consequences and often involves physical dependence.

In drug abuse, an individual may use substances for recreational purposes or to cope with stress but does not experience withdrawal symptoms if they stop using. However, in addiction, individuals develop a physical dependence on drugs and experience withdrawal symptoms when they try to quit.

Another significant difference between drug abuse and addiction is psychological dependence. In drug abuse, individuals continue using substances without experiencing intense cravings or feeling compelled to use them; however, in addition, individuals often have a strong psychological urge to use drugs despite adverse consequences.

Individuals who engage in drug abuse require increasingly higher doses of substances to achieve the desired effect. However, in addition, individuals develop a tolerance to drugs, meaning that they need more significant amounts of substances to experience the same effects as before.

Drug abuse results in changes in behavior, such as neglecting responsibilities or engaging in risky behaviors. In contrast, addiction is characterized by compulsive drug-seeking behavior despite negative consequences and can significantly impact an individual’s life and relationships.

While both drug abuse and addiction are serious problems that require professional help, the treatment approaches may differ. Drug abuse is addressed through therapy or self-help methods; however, addiction typically requires intensive treatment programs, including detoxification, therapy, and support groups.

Secondary differences between drug abuse and addiction include factors such as the severity of substance use, underlying causes, and co-occurring mental health disorders. It is essential to understand the differences between drug abuse and addiction to seek appropriate help and support for individuals struggling with these issues. 

What is the Difference Between Drug Dependence vs. Addiction?

The main difference between drug dependence and addiction is that dependence refers to the body’s physical adaptation to a substance, characterized by tolerance and withdrawal symptoms, while addiction is a chronic brain disease marked by compulsive drug use despite harmful consequences, according to the Medical News Today article, “Addiction vs. dependence: What is the difference?” by Meara Withe on (December 2023).

Dependence occurs without addiction, but addiction almost always involves dependence. This means that while a person can be physically dependent on a drug, they do not necessarily have the compulsive behaviors and psychological aspects of addiction. On the other hand, someone with an addiction will also experience dependence as their body becomes reliant on the substance. Still, there is an added element of craving and loss of control over use.

Drug dependence is primarily caused by physical changes in the brain and body due to repeated exposure to a substance. Addiction, however, is influenced by various factors such as genetics, environment, mental health issues, and social influences.

Dependence develops relatively quickly after regular drug use, sometimes within a few weeks. Addiction, on the other hand, may take longer to develop and can vary from person to person depending on their individual circumstances.

Dependence is often seen as a milder form of substance use disorder compared to addiction. While dependence causes physical discomfort and withdrawal symptoms, addiction leads to severe consequences such as financial problems, strained relationships, and even overdose or death.

Therefore, it is essential to understand the difference between drug dependence and addiction as they require different treatment approaches. While dependence is managed through detoxification and addressing physical symptoms, addiction requires a more comprehensive approach that also addresses the psychological and social aspects of the disease.

What is the Difference Between Drug Tolerance vs. Dependence?

The main difference between drug tolerance and dependence is that tolerance refers to the body’s diminished response to a substance over time, requiring higher doses to achieve the same effects, while dependence occurs when the body physically relies on a drug, and stopping use leads to withdrawal symptoms, according to the Medical News Today article “Addiction vs. dependence: What is the difference?” by Meara Withe (2023).

Tolerance refers to a physiological adaptation where the body requires a higher dose of a substance to achieve the same effect due to repeated use. In contrast, dependence occurs when the body becomes reliant on a substance, leading to withdrawal symptoms if the substance is abruptly stopped.

While both conditions are related to substance use, they represent different aspects of how the body interacts with drugs. In addition to the primary distinction, secondary differences include the nature of the symptoms associated with each condition. Tolerance is characterized by a diminishing response to a drug, necessitating increased dosages for the same effect, which can occur with both prescribed medications and recreational drugs.

Dependence, however, is marked by physical and psychological withdrawal symptoms when the substance is reduced or eliminated, such as headaches, nausea, anxiety, and irritability. This reliance on the substance can develop over time and is often a result of prolonged exposure.

Lastly, while tolerance can exist without dependence, the two often occur together and lead to addiction.

What is the Difference Between Drug Addiction vs. Alcoholism?

The main difference between drug addiction and alcoholism is that alcoholism specifically refers to addiction to alcohol, according to Alozai UU, Sharma S. Drug and Alcohol Use: StatPearls Publishing Journal; 2024. In contrast, drug addiction encompasses a broader range of substances, including illegal drugs, prescription medications, and other psychoactive substances. This means that while alcoholism is a type of drug addiction, not all drug addictions are alcoholism.

While both drug addiction and alcoholism can have damaging effects on the body, they may affect different systems in different ways. For example, excessive alcohol consumption can lead to liver damage and cardiovascular issues, while certain drugs may impact brain function and cause respiratory problems.

Due to the unique characteristics and effects of alcohol compared to other drugs, treatment approaches for alcoholism differ from those for drug addiction. For example, medications such as disulfiram and naltrexone are specifically designed to treat alcoholism, while other medications may be used to address withdrawal symptoms or co-occurring mental health disorders.

Another key difference between drug addiction and alcoholism is the societal stigma surrounding each issue. While both are recognized as serious health concerns, there tends to be more judgment and shame associated with alcoholism due to its legal status and widespread social acceptance. This makes it difficult for individuals struggling with alcoholism to seek help, leading to delays in treatment or lack of access altogether.

What Are The Types of Drug Addiction?

The types of drug addiction are Prescription drug addiction, inhalant addiction, opioid addiction, stimulant addiction, hallucinogen addiction, and marijuana addiction. According to the National Institute on Drug Abuse’s “Commonly Used Drugs Charts” (September 2023).

1. Prescription Drug Addiction

Prescription drug addiction occurs when individuals misuse medications that are legally prescribed to them, often for pain relief, anxiety, or sleep disorders. Commonly abused prescription drugs include opioids (like oxycodone), benzodiazepines (like Xanax), and stimulants.

The causes of prescription drug addiction include chronic pain, mental health disorders, or a history of substance abuse. Additionally, societal pressures, easy access to prescriptions, and the normalization of medication use can contribute to misuse.

The effects of prescription drug addiction are severe and include physical dependence, withdrawal symptoms, impaired cognitive function, and increased risk of overdose. Long-term misuse can lead to significant health issues, including organ damage and mental health disorders.

Treatment for prescription drug addiction involves medical detoxification, behavioral therapy, and support groups. Medications such as methadone or buprenorphine may be used to manage withdrawal symptoms and cravings, while therapy addresses underlying psychological issues.

2. Inhalant Addiction

Inhalant addiction refers to the compulsive use of substances that produce chemical vapors, which are inhaled for their psychoactive effects. Common inhalants include glue, paint thinners, and nitrous oxide.

Inhalant addiction is often driven by factors such as peer pressure, curiosity, and a desire for a quick and intense high. It is particularly prevalent among adolescents due to the accessibility and low cost of these substances.

The effects of inhalant addiction include short-term euphoria, dizziness, and hallucinations. Still, they can also lead to severe health risks such as brain damage, organ failure, and sudden death from asphyxiation or cardiac arrest.

Treatment for inhalant addiction typically involves behavioral therapies and counseling to address the underlying issues that lead to substance use. Support groups and educational programs can also help individuals understand the dangers of inhalant use and promote recovery.

3. Opioid Addiction

Opioid addiction is characterized by the compulsive use of opioid drugs, which include both illegal substances like heroin and prescription medications such as morphine and fentanyl. This addiction often stems from the drugs’ pain-relieving properties.

The causes of opioid addiction include chronic pain, genetic predisposition, and psychological factors such as anxiety or depression. The over-prescription of opioids in the past has also contributed significantly to the epidemic of opioid misuse.

The effects of opioid addiction can be devastating, leading to physical dependence, increased tolerance, and withdrawal symptoms. Long-term use can result in respiratory depression, overdose, and a host of social and economic problems.

Treatment for opioid addiction usually involves a combination of medication-assisted treatment (MAT) using drugs like methadone or buprenorphine, along with counseling and support groups. This integrated approach helps manage withdrawal symptoms and reduce cravings while addressing the psychological aspects of addiction.

4. Stimulant Addiction

Stimulant addiction involves the misuse of drugs that increase alertness, attention, and energy. Common stimulants include cocaine, methamphetamine, and prescription medications like Adderall.

The causes of stimulant addiction include a desire for increased energy or focus, social pressures, and underlying mental health conditions. Many individuals may initially use stimulants to enhance performance or cope with stress.

The effects of stimulant addiction include euphoria, increased heart rate, and heightened alertness, but it also leads to severe consequences such as anxiety, paranoia, cardiovascular issues, and potential overdose.

Treatment for stimulant addiction often includes behavioral therapies, counseling, and support groups. While there are currently no FDA-approved medications specifically for stimulant addiction, therapies focus on changing behaviors and coping strategies.

5. Hallucinogen Addiction

Hallucinogen addiction refers to the compulsive use of substances that alter perception, mood, and cognitive processes. Common hallucinogens include LSD, psilocybin (magic mushrooms), and peyote.

The causes of hallucinogen addiction stem from a desire for altered states of consciousness, exploration of spirituality, or escapism. Social environments that encourage drug use also play a significant role.

The effects of hallucinogen addiction include visual and auditory hallucinations, altered sense of time, and emotional instability. While not typically associated with physical dependence, they lead to psychological issues and persistent changes in perception.

Treatment for hallucinogen addiction generally focuses on psychotherapy and counseling to address the psychological aspects of addiction. Support groups and education about the risks of hallucinogen use can also aid in recovery.

6. Marijuana Addiction

Marijuana addiction, or cannabis use disorder, is characterized by the compulsive use of marijuana despite negative consequences. It can involve both recreational and medicinal use of cannabis.

The causes of marijuana addiction include genetic predisposition, social influences, and the perception of marijuana as a harmless substance. Individuals use it to cope with stress, anxiety, or other mental health issues.

The effects of marijuana addiction include impaired cognitive function, mood swings, and withdrawal symptoms such as irritability and insomnia. Long-term use leads to decreased motivation and difficulties in personal and professional relationships.

Treatment for marijuana addiction involves behavioral therapies, counseling, and support groups. Cognitive-behavioral therapy (CBT) is often effective in helping individuals change their use patterns and develop healthier coping strategies.

What are the Signs and Symptoms of Drug Addiction?

The main signs and symptoms of drug addiction are  intense craving for the substance, neglecting personal and professional responsibilities, developing tolerance and wanting higher doses, withdrawal symptoms, and ongoing use, as suggested by the Mayo Clinic article on “Drug addiction substance use disorder” (October 2022):

• Intense Cravings for the Substance: One of the hallmark signs of drug addiction is experiencing intense cravings for the substance. These cravings are often uncontrollable and can dominate a person’s thoughts, making it difficult to focus on anything else. The brain’s reward system is hijacked by the substance, leading to a powerful desire to use the drug repeatedly to achieve the same pleasurable effects.
• Neglecting Personal and Professional Responsibilities: Individuals struggling with drug addiction often neglect their personal and professional responsibilities. This manifests as poor performance at work or school, neglecting family obligations, and withdrawing from social activities. 
• Developing Tolerance and Needing Higher Doses: Tolerance is a common symptom of drug addiction, where the person needs increasingly larger doses of the substance to achieve the same effect. This occurs because the body becomes accustomed to the drug, reducing its effectiveness over time. As tolerance builds, the risk of overdose and other health complications increases.
• Experiencing Withdrawal Symptoms When Not Using: Withdrawal symptoms are physical and psychological effects that occur when a person stops using the substance. These symptoms can include anxiety, irritability, nausea, sweating, shaking, and severe cravings. The fear of experiencing these unpleasant symptoms often drives individuals to continue using the drug, perpetuating the cycle of addiction.
• Continued Use Despite Negative Consequences: Despite facing negative consequences such as health problems, legal issues, financial difficulties, and strained relationships, individuals with drug addiction continue to use the substance. This persistence indicates a loss of control over drug use and an inability to stop despite knowing the harm it causes.

Identifying these symptoms helps individuals take the first steps toward recovery and seek appropriate treatment.

What are the Causes of Drug Addiction?

The primary causes of drug addiction include genetic predisposition, environmental factors, and psychological factors, as stated by the National Institute of Drug Abuse study titled “Understanding Drug Use and Addiction DrugFacts” ( October 2022).

1. Genetic Predisposition: Individuals with a family history of addiction are more susceptible to developing drug addiction. Genetic factors account for about half of a person’s risk for addiction.
2. Environmental Factors: Exposure to drugs at an early age, peer pressure, and social influences significantly contribute to the likelihood of drug use and subsequent addiction. Family dynamics, economic status, and quality of life also play crucial roles.
3. Psychological Factors: Mental health disorders, such as depression, anxiety, and trauma, increase the risk of drug addiction. Individuals use drugs as a coping mechanism to deal with stress or emotional pain, which can lead to addiction.

Understanding these causes helps develop targeted prevention and treatment strategies to address the root issues.

What are the Effects of Drug Addiction?

The effects of drug addiction include physical health, mental health, and social impact, as suggested by the Mayo Clinic article on “Drug addiction (substance use disorder” (October 2022).

1. Physical Health: Drug addiction leads to severe organ damage, a weakened immune system, and an increased risk of infectious diseases. Chronic use of drugs causes long-term damage to the liver, heart, and brain, among other organs.
2. Mental Health: Addiction often exacerbates mental health issues, leading to conditions such as anxiety, depression, psychosis, and cognitive impairments. The changes in brain chemistry caused by drug use can have lasting effects on an individual’s mental health.
3. Social Impact: Drug addiction strains relationships with family and friends, results in job loss, and leads to legal issues. The social consequences of addiction are profound, often leading to isolation, financial problems, and involvement with the criminal justice system.

Addressing these effects requires a holistic approach considering the individual’s physical, mental, and social well-being.

How Can Drugs Affect Your Mental Health?

Drug use causes changes in brain chemistry and structure, leading to a variety of mental health issues like anxiety and depression, psychosis, and mood swings,  according to the National Institute on Drug Abuse article titled “Understanding Drug Use and Addiction Drug Facts” (October 2022).

• Anxiety and Depression: Many drugs can alter the balance of neurotransmitters in the brain, causing feelings of anxiety or depression. This may be due to the direct effects of the drug itself or from withdrawal symptoms when stopping use.
• Psychosis: Some drugs, such as stimulants or hallucinogens, can trigger psychotic episodes in those who are predisposed to them. This can result in delusions, paranoia, and other symptoms of psychosis.
• Mood Swings: Drugs can disrupt the brain’s reward system, causing extreme mood changes. This can lead to intense feelings of euphoria or dysphoria, which may contribute to addiction and co-occurring mental health disorders.
• Memory and Cognitive Functioning: Drug use can impair memory and cognitive functioning, making it difficult to process information and make decisions. This can have a significant impact on daily life and overall well-being.
• Co-Occurring Disorders: It’s common for substance use disorders to co-occur with mental health disorders, such as depression, anxiety, or bipolar disorder. This creates a complex situation where both issues must be addressed simultaneously for successful treatment.

These are just a few of the ways that drugs can affect mental health. It’s important to understand that mental health and substance abuse are closely intertwined, and addressing both is crucial for overall well-being.

How Do Drugs Affect Your Physical Health?

Drug use affects your physical health by causing organ damage, cardiovascular problems, infectious diseases, nausea and vomiting, malnutrition, pregnancy complications, and physical dependence, as reviewed by the Better Health Channel article titled” How Drugs Can Affect Your Body”:

• Organ Damage: Drugs, especially the liver and kidneys, strain the body’s organs. This leads to long-term damage and even organ failure in severe cases.
• Cardiovascular Problems: Many drugs, including stimulants and opioids, cause cardiovascular problems such as heart attacks or strokes. These substances also increase blood pressure and heart rate, leading to additional health complications.
• Infectious Diseases: Injection drug use puts individuals at risk for contracting infectious diseases such as HIV/AIDS or hepatitis C from contaminated needles.
• Respiratory Issues: Smoking or inhaling drugs damages the lungs and respiratory system, leading to chronic coughing, shortness of breath, and other respiratory issues.
• Nausea and Vomiting: Many drugs, including alcohol and opioids, cause nausea and vomiting. This strains the body and increases the risk of choking or aspiration.
• Malnutrition: Chronic drug use leads to poor eating habits and malnutrition. This weakens the immune system and makes individuals more susceptible to illness and disease.
• Pregnancy Complications: Drug use during pregnancy has detrimental effects on both the mother and developing baby. This includes preterm labor, birth defects, and neonatal abstinence syndrome.
• Physical Dependence and Withdrawal: Continued drug use results in physical dependence, where the body relies on the substance to function normally. When use is stopped, individuals experience withdrawal symptoms such as nausea, sweating, and tremors.

It’s essential to recognize that drugs not only affect mental health but also have significant impacts on physical health. Seeking help for substance abuse is crucial for addressing these issues and improving overall well-being.

How Does Addiction Affect the Brain?

Addiction affects the brain by altering its structure and function, specifically in the areas related to reward, memory, motivation, and self-control, as suggested by the Yale Medicine article titled “ How the addicted brain works” (May 2022),

• Changes in Reward Pathways: Drugs hijack the brain’s reward system by flooding it with dopamine (a neurotransmitter associated with pleasure). This leads to feelings of euphoria and reinforces drug use.
• Memory Associations: The brain forms strong associations between drug use and pleasurable experiences, making it difficult to resist cravings or triggers for drug use.
• Decreased Motivation: As addiction progresses, individuals may become less motivated to engage in activities that do not involve drug use, leading to social isolation and neglect of responsibilities.
• Impaired Self-Control: Drug use alters the brain’s prefrontal cortex, which is responsible for decision-making and self-control. This makes it challenging to resist impulses and make rational decisions.
• Tolerance and Withdrawal: The brain adapts to chronic drug use by becoming tolerant to its effects. This means individuals need higher doses to achieve the desired effect and experience withdrawal symptoms when they stop using.

It’s crucial to understand the underlying neurological changes that occur with addiction to address and manage it effectively.

What are the Stages of Drug Addiction?

The stages of drug addiction are experimentation, regular use, dependence, addiction, recovery, and relapse, as portrayed in an article by the American Addiction Centers titled “The Addiction Cycle: What Are The Stages of Addiction?” (April 2026).

• Experimentation: Initial use is driven by curiosity or peer pressure, often considered harmless. At this stage, individuals may try a substance for the first time, typically in social settings, without intending to continue use.
• Regular Use: Increased frequency of use characterizes this stage, potentially leading to dependence and addiction. Individuals begin to use the substance more regularly, which can impact their daily lives and responsibilities.
• Dependence: Dependence involves physical and psychological reliance on the substance, marked by withdrawal symptoms when not using it. This stage is characterized by the body’s adaptation to the substance, requiring more of it to achieve the same effects, leading to a cycle of regular use and dependence.
• Addiction: Addiction is marked by compulsive use despite harmful consequences, requiring specialized treatment. At this stage, the individual loses control over their substance use, often prioritizing it over other aspects of life, including health, relationships, and responsibilities.
• Recovery: The process of overcoming addiction involves medical, psychological, and social support. Recovery is a long-term process that includes detoxification, therapy, support groups, and sometimes medication to manage withdrawal symptoms and prevent relapse.
• Relapse: Relapse refers to returning to substance use after a period of abstinence, highlighting the need for ongoing support and aftercare. It is a common part of the recovery process and underscores the chronic nature of addiction, necessitating continuous monitoring and support to maintain sobriety.

What are the Most Common Substances Used for Drug Addiction?

The most common substances that lead to addiction are heroin, cocaine, prescription opioids, inhalants, Methamphetamine, Benzodiazepines, Morphine, and LSD, according to a study titled “The Neurobiology of Substance Use, Misuse and Addiction” (November 2016):

Heroin: Heroin is a highly addictive opioid derived from morphine, which is extracted from the seed pod of certain poppy plants. It is known for its rapid onset of euphoria, often called a “rush.” 

However, heroin use carries severe health consequences, including a high risk of overdose due to its potent effects on the central nervous system. Chronic use leads to significant physical dependence, where the body adapts to the presence of the drug, and withdrawal symptoms become severe when usage stops. 

• Cocaine: Cocaine is a powerful stimulant that affects the brain’s reward pathway by increasing levels of dopamine, leading to intense feelings of euphoria and increased energy. However, its use results in significant cardiovascular problems, including heart attacks and strokes, due to its effects on the heart and blood vessels. 
• Prescription Opioids: Prescription opioids are medications typically prescribed for pain relief but have a high potential for misuse and addiction. These drugs, such as oxycodone, hydrocodone, and fentanyl, work by binding to opioid receptors in the brain, reducing the perception of pain and producing feelings of euphoria. 
• Misuse leads to physical dependence and addiction, as well as an increased risk of overdose, particularly when taken in higher doses or combined with other substances like alcohol. 
• Inhalants: Inhalants are diverse substances inhaled to achieve a psychoactive effect. These include household products like glue, paint thinners, and aerosol sprays. The use of inhalants causes immediate effects such as euphoria, dizziness, and hallucinations, but they also pose severe health risks. 
• Methamphetamine: Methamphetamine is a stimulant that affects the central nervous system. It is known for its powerful euphoric effects, which lead to rapid addiction. Methamphetamine use has devastating physical and mental health consequences, including severe dental problems (“meth mouth”), extreme weight loss, skin sores, and increased risk of infectious diseases. 
• Benzodiazepines: Benzodiazepines are medications commonly prescribed for anxiety and sleep disorders. These drugs, such as diazepam (Valium) and alprazolam (Xanax), enhance the effect of the neurotransmitter GABA, producing a calming effect. However, they have a high potential for dependence and addiction, mainly when used for extended periods or in higher doses than prescribed. 
• Morphine: Morphine is a powerful painkiller derived from the opium poppy. It is used medically to treat severe pain but has a high potential for addiction and abuse. Morphine works by binding to opioid receptors in the brain and spinal cord, reducing the perception of pain and producing euphoria. 
• Chronic use leads to tolerance, where higher doses are needed to achieve the same effect, and physical dependence, where withdrawal symptoms occur if the drug is abruptly discontinued. 
• LSD: LSD (lysergic acid diethylamide) is a hallucinogen that profoundly alters perception, mood, and cognitive processes. It is known for causing intense visual and auditory hallucinations, as well as significant changes in thought patterns and emotions. While LSD is not considered physically addictive, it can cause psychological dependence, where users feel compelled to continue using the drug despite potential negative consequences. 

The use of LSD leads to severe mental health issues, including persistent psychosis and hallucinogen persisting perception disorder (HPPD), where users experience flashbacks of their drug experience long after the effects have worn off.

What are the Mostly Used Drug Addiction Screening Tests?

The most used drug addiction screening tests are  DAST-10, CRAFFT, SBIRT, Urine Drug Test (UDT), NIDA Quick Screen, CAGE Questionnaire, and MAST, according to Pilowsky, D. J., & Wu, T. (2012). Screening for alcohol and drug use disorders among adults in primary care: A review. Substance Abuse and Rehabilitation Journal.

• DAST-10: The Drug Abuse Screening Test (DAST-10) is a brief, self-report instrument designed to screen for drug abuse. It consists of 10 yes-or-no questions that assess the frequency and impact of drug use on the individual’s life. 
• CRAFFT: The CRAFFT screening tool is designed for adolescents to identify risky behaviors and substance use. It includes six questions that focus on the individual’s experiences with drugs and alcohol, such as using substances to relax, using them alone, and experiencing memory blackouts. 
• SBIRT: Screening, Brief Intervention, and Referral to Treatment (SBIRT) is a comprehensive approach that integrates screening for substance use disorders with brief counseling and referral to specialized treatment. 
• Urine Drug Test (UDT): A Urine Drug Test (UDT) is a laboratory test that detects the presence of drugs in the urine. It is commonly used for monitoring drug use, particularly in clinical settings, workplaces, and legal contexts. 
• NIDA Quick Screen: The National Institute on Drug Abuse developed the NIDA Quick Screen to rapidly assess substance use. It consists of a few questions about the frequency of use of various substances, including prescription drugs, illegal drugs, tobacco, and alcohol. 
• CAGE Questionnaire: The CAGE Questionnaire is a widely used screening tool for identifying alcohol and drug use disorders. It consists of four questions that focus on the individual’s feelings and behaviors related to substance use:

1. Have you ever felt you should cut down on your drinking or drug use?
2. Have people annoyed you by criticizing your drinking or drug use?
3. Have you ever felt bad or guilty about your drinking or drug use?
4. Have you ever had a drink or used drugs first thing in the morning to steady your nerves or get rid of a hangover (eye-opener)?

A positive response to two or more questions suggests a potential substance use disorder that warrants further assessment.

• MAST: The Michigan Alcohol Screening Test (MAST) is another tool used to identify alcohol and drug dependence. It includes 22 questions that cover various aspects of substance use and its impact on the individual’s life. The questions address issues such as legal problems, social consequences, and physical health effects related to substance use. The MAST is beneficial in clinical settings to identify individuals who will benefit from treatment for substance use disorders.

These screening tests are valuable tools in the early detection and management of drug addiction, helping healthcare providers to develop effective treatment plans tailored to the needs of individuals struggling with substance use disorders.

What are the Types of Drug Addiction Treatment?

The types of drug addiction treatment include medical detox, inpatient rehab, patient hospitalization program, outpatient, telehealth, Intensive Outpatient Program (IOP), therapy, and holistic treatment, according to an article on Cleveland Clinic titled “Substance Use Disorder (SUD)” (October 2022).:

• Medical Detox: A supervised process to manage withdrawal symptoms and ensure safety during detoxification. Medical professionals monitor patients 24/7, providing medication and support as needed.
• Inpatient Rehab: Residential programs provide intensive support and therapy for addiction recovery. Patients live in a controlled environment, receiving round-the-clock care and structured activities.
• Partial Hospitalization Program (PHP): These structured programs offer comprehensive treatment while allowing individuals to live at home. Patients attend treatment sessions during the day but return home in the evenings. PHPs balance intensive care with maintaining some aspects of daily life.
• Outpatient: Flexible treatment options for individuals who need support while maintaining daily activities. Patients attend scheduled therapy sessions and support groups while living at home.
• Telehealth: Remote treatment options using digital platforms for therapy and counseling. Patients can access care from the comfort of their homes via video calls or phone sessions.
• Intensive Outpatient Program (IOP): Programs offering more intensive support than standard outpatient treatment.
• Patients attend multiple therapy sessions per week while living at home.
• IOPs provide a higher level of care without the need for full-time residency.
• Therapy: Various therapeutic approaches address the psychological aspects of addiction. Options include cognitive-behavioral therapy, motivational interviewing, and family therapy.
• Holistic Treatment: Complementary therapies such as yoga, meditation, and acupuncture are used alongside traditional treatments. These approaches focus on well-being and address mind, body, and spirit.
• Aftercare: Ongoing support to prevent relapse and maintain recovery after initial treatment. This may include support groups, continued therapy, and lifestyle adjustments. Aftercare is crucial for long-term success and helps individuals navigate challenges in recovery.

Is Drug Addiction a Disease?

Yes, drug addiction is recognized as a chronic disease that affects brain function and behavior. The National Institute on Drug Abuse defines addiction as a “chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, despite harmful consequences.” This definition highlights the key characteristics of addiction: it is a chronic condition, it involves compulsive behavior, and it results in negative consequences.

Is Drug Addiction Genetic?

Yes. Genetic factors account for about 40-60% of a person’s likelihood to develop an addiction, according to Substance Abuse and Mental Health Services Administration (US);: The Surgeon General’s Report on Alcohol, Drugs, and Health [Internet]. Washington (DC): US Department of Health and Human Services; 2016.

Is Drug Addiction a Disability?

Yes. Drug addiction can be considered a disability, especially when it impairs major life activities. According to the Americans with Disabilities Act (ADA), a disability is “a physical or mental impairment that substantially limits one or more major life activities.” Drug addiction falls under this definition, as it affects both physical and mental capabilities and can greatly limit an individual’s ability to participate in daily activities.

Why is Drug Abuse More Common with Teens?

Teens are more susceptible to drug abuse due to peer pressure, curiosity, and developmental factors, according to Winters KC, Arria A. Adolescent Brain Development and Drugs. Prev Res. PMCID.

Peer pressure is a major factor in why drug abuse is more common among teenagers. During adolescence, teens are highly influenced by their peers and want to fit in with their social groups. This can lead them to engage in risky behaviors, such as experimenting with drugs, to gain acceptance and approval from their peers.

Why Do People Use Drugs?

People use drugs for various reasons, including stress relief, peer influence, and coping with mental health issues,  as seen in Boys A, Marsden J, Strang J. Understanding reasons for drug use amongst young people: a functional perspective. Health Educ Res. 2001. In some cases, individuals also use drugs as a form of self-medication or to enhance their mood and pleasure.

Is Drug Addiction a Choice?

While the initial decision to use drugs is voluntary, addiction is a disease that alters brain function, making it difficult to control. Addiction is not a choice but rather a chronic and relapsing condition that requires medical treatment, according to Pickard H. The Purpose in Chronic Addiction. AJOB Neurosci. 2012.

Is Drug Addiction Considered a Disability?

Yes, under certain circumstances, drug addiction can be classified as a disability, particularly when it significantly limits major life activities, according to McCrory EJ, Mayes L. Understanding Addiction as a Developmental Disorder: An Argument for a Developmentally Informed Multilevel Approach. 2015: PMCID.
