Addiction is a chronic illness that is extremely detrimental to one’s life and well-being. Though it affects millions of Americans, many people consider addiction shameful and avoid seeking treatment. Understanding the course of the disease as well as its risk factors can help change people’s inaccurate perceptions. Like many other illnesses, addiction presents a life-long challenge that must be managed to avoid severe consequences.
What is addiction?
Addiction is a disease that involves compulsive use of drugs and alcohol to the detriment of one’s life and well-being. Though it’s possible to become addicted to other things including gambling or sex, addiction to drugs, alcohol, and other substances tend to have the worst effects on a person’s life. Alcohol, marijuana, prescription drugs, opioids, methamphetamines, and stimulants such as cocaine are some of the most commonly abused substances.
Addiction is diagnosed by a clinician who takes into account a person’s history of abuse and behavior. Symptoms of addiction are clustered according to their effects. These behavioral clusters include impaired control when it comes to substance use, social or professional impairment, risky use, and pharmacologic symptoms. These are all areas that can be affected by addiction to varying degrees. Individuals may experience different clusters of symptoms with varying severity, which is why addiction treatment is often individualized.
Addiction statistics
National data help describe the scale of substance use disorders and overdose deaths. These figures refer to different measures and reporting years:
- In 2025, an estimated 44.6 million people aged 12 or older in the United States (15.3%) had a substance use disorder in the past year, according to SAMHSA.
- In the same 2025 survey, an estimated 26.0 million people aged 12 or older had a drug use disorder in the past year. This group is included within the overall substance use disorder estimate, not an additional population.
- CDC final mortality data recorded 79,384 drug overdose deaths in the United States in 2024.
Sources: SAMHSA 2025 National Survey on Drug Use and Health and CDC drug overdose deaths, 2023–2024. SAMHSA survey estimates describe the civilian, noninstitutionalized population aged 12 or older; CDC mortality counts measure deaths, not the prevalence of a disorder.
Addiction can have many detrimental effects on one’s life. Some of these behavioral signs and symptoms may be evident to the individual themselves or to others around them. These symptoms include:
- Taking more of a substance or using substances for a longer period than intended
- Failed attempts to quit
- Spending more and more time obtaining, using, or recovering from substance or alcohol use
- Cravings for drugs and alcohol
- Continued substance use that interferes with professional or personal duties
- Continued substance use despite detrimental effects it may have on one’s health
- Interpersonal conflict caused by substance use
- Reduced interest in recreational activities due to substance use
- Using substances in risky situations such as while driving
- Tolerance that occurs when the same amount of the substance no longer has the same effect, which leads to the use of higher doses
- Unpleasant withdrawal symptoms that occur when substance use is stopped
Diagnosing addiction
A qualified clinician diagnoses substance use disorder through a clinical assessment. Under DSM-5-TR criteria, severity is generally classified by the number of applicable symptoms occurring within a 12-month period: mild (2–3), moderate (4–5), or severe (6 or more). A symptom checklist alone is not a diagnosis; a clinician considers the substance involved and the person’s circumstances.
Addiction is often misunderstood, and individuals who suffer from addiction are sometimes believed to be at fault for their illness. However, this explanation does not take into account the many risk factors and circumstances that can predispose a person to addiction. These include both biological factors such as genetics and environmental factors such as history of trauma.
Many biological factors can create predispositions to addiction. One of the most common is genetics. This means that people with close family members who suffer from addiction or mental illness may be predisposed to the same problems. Other biological factors include brain chemistry and genetic mental health issues.
Environmental factors are those factors in a person’s life and surroundings that can lead to addiction. These include family and friends, life stresses, and lack of access to social and community resources. For example, addiction can be learned by observation if everyone around you abuses drugs or alcohol. Environmental factors may be hard to tease apart from biological factors as being raised by parents who are addicted to drugs and alcohol has both genetic and environmental influence on children.
Mitigating factors
Though risk factors can have a strong influence on the likelihood of developing addiction, some positive mitigating factors can be protective against the probability of addiction. For example, having strong bonds with loving and supportive family and friends. These can serve as an outlet for stress instead of drugs. Community resources such as after-school clubs and free or low-cost mental health resources can also help people avoid addiction. Participation in hobbies or team sports that can improve one’s overall well-being and improve relationships with others can also be a mitigating factor.
Consequences of addiction
Addiction is so harmful because it can affect many aspects of a person’s life, including mental and physical health. These effects may be severe and potentially irreversible. Some of the physical effects of addiction include:
- Lung disease
- Cardiovascular disease
- Stroke
- Cancer
- Infectious disease such as HIV/AIDS or Hepatitis as a result of shared needles or risky sexual behavior related to drug use
- Mental health problems such as anxiety or depression
- Increased risk of injury
- Potential overdose
- Suicide or suicidal ideation
- Adverse effects of drugs and alcohol on a fetus if used while pregnant
Addiction Treatment
It’s difficult to overcome addiction and substance abuse alone. Addiction treatment is designed to provide individuals with the tools they need to manage their addiction and prevent relapse to promote long-term recovery. Recovery is not an end-goal of addiction treatment; since addiction is chronic, recovery is an ongoing process.
Addiction treatment helps individuals understand the biological and environmental factors that contribute to their substance abuse and equips them with the skills needed to maintain their recovery. Addiction treatment progresses through several stages, known as levels of care, depending on the severity of addiction and other factors such as co-occurring mental health issues.
Medical Detox
Medical detox may be recommended when withdrawal requires medical supervision. It involves monitoring and treatment to help manage withdrawal symptoms and support stabilization. The need for detox depends on the substance used, medical history, and a clinical assessment. Detox alone does not address all aspects of a substance use disorder; ongoing treatment and recovery support may be needed.
Inpatient treatment
Inpatient treatment is the highest level of care in addiction treatment, requiring individuals to undergo full-time treatment while living in a residential facility. For people whose home environment is unstable or dangerous, inpatient treatment may be the most effective. This can help immerse individuals in a supportive environment surrounded by others who are on the same recovery journey. In addition to regular therapy sessions and peer group meetings, individuals in inpatient programs can take part in healthy activities during their free time such as meditation and yoga.
Outpatient treatment
Outpatient treatment allows people to attend scheduled treatment while living at home or in a supportive environment. The appropriate level of care depends on an individualized assessment. Intensive outpatient treatment provides more structure than standard outpatient visits and may allow participants to continue work, school, and family responsibilities. The schedule and duration depend on the program and the person's clinical needs.
Addiction FAQs
Is addiction genetic?
Addiction may be motivated by many factors, including genetics. Some clinicians believe that up to 40 to 60% of addiction can be explained by genetic factors. However, genetics alone do not paint the whole picture. Many environmental factors including an unstable home environment or history of trauma can also increase a person’s likelihood of developing addiction.
How long does addiction treatment last?
Addiction treatment is not a set length for everyone. Treatment is individualized according to the severity of the addiction and other individual needs. Typical addiction treatment programs may last anywhere from 30 to 90 days, but personal assessment will determine how long a program would be most effective for you.
Can I become addicted to a substance that was prescribed by a doctor?
Some of the most dangerous substances of abuse are prescription drugs. Even if a medication was prescribed or is taken as prescribed, it is possible to become addicted to that substance. It’s important to monitor your own behavior for signs of possible addiction.
Is substance abuse the same as addiction?
Substance abuse and addiction are often used interchangeably but they are slightly different. Substance abuse is the pattern of problematic drug use that can affect many facets of a person’s life including health and professional life. Addiction is a compulsive need to use a substance due to physical or psychological dependence. Repeated substance use can lead to addiction, which can subsequently worsen substance abuse.
