What Is Addiction?
Addiction is a complex condition, a brain disease that is manifested by compulsive substance use despite harmful consequence. People with addiction (severe substance use disorder) have an intense focus on using a certain substance(s), such as alcohol or drugs, to the point that it takes over their life. They keep using alcohol or a drug even when they know it will causes problems. Yet a number of effective treatments are available and people can recover from addiction and lead normal, productive lives.
People can develop an addiction to:
- PCP, LSD and other hallucinogens
- Inhalants, such as, paint thinners and glue
- Opioid pain killers, such as codeine and oxycodone, heroin
- Sedatives, hypnotics and anxiolytics (medicines for anxiety such as tranquilizers)
- Cocaine, methamphetamine and other stimulants
People with a substance use disorder have distorted thinking, behavior and body functions. Changes in the brain’s wiring are what cause people to have intense cravings for the drug and make it hard to stop using the drug. Brain imaging studies show changes in the areas of the brain that relate to judgment, decision making, learning, memory and behavior control.
These substances can cause harmful changes in how the brain functions. These changes can last long after the immediate effects of the drug — the intoxication. Intoxication is the intense pleasure, calm, increased senses or a high caused by the drug. Intoxication symptoms are different for each substance.
Over time people with addiction build up a tolerance, meaning they need larger amounts to feel the effects.
According to the National Institute on Drug Abuse, people begin taking drugs for a variety of reasons, including:
- to feel good — feeling of pleasure, “high”
- to feel better — e.g., relieve stress
- to do better — improve performance
- curiosity and peer pressure
People with addictive disorders may be aware of their problem, but be unable to stop it even if they want to. The addiction may cause health problems as well as problems at work and with family members and friends. The misuse of drugs and alcohol is the leading cause of preventable illnesses and premature death.
Symptoms of substance use disorder are grouped into four categories:
- Impaired control: a craving or strong urge to use the substance; desire or failed attempts to cut down or control substance use
- Social problems: substance use causes failure to complete major tasks at work, school or home; social, work or leisure activities are given up or cut back because of substance use
- Risky use: substance is used in risky settings; continued use despite known problems
- Drug effects: tolerance (need for larger amounts to get the same effect); withdrawal symptoms (different for each substance)
Many people experience both mental illness and addiction. The mental illness may be present before the addiction. Or the addiction may trigger or make a mental disorder worse.
How Is Addiction Treated?
Effective treatments for addiction are available.
The first step on the road to recovery is recognition of the problem. The recovery process can be hindered when a person denies having a problem and lacks understanding about substance misuse and addiction. The intervention of concerned friends and family often prompts treatment.
A health professional can conduct a formal assessment of symptoms to see if a substance use disorder exists. Even if the problem seems severe, most people with a substance use disorder can benefit from treatment. Unfortunately, many people who could benefit from treatment don’t receive help.
Because addiction affects many aspects of a person’s life, multiple types of treatment are often required. For most, a combination of medication and individual or group therapy is most effective. Treatment approaches that address an individual’s situation and any co-occurring medical, psychiatric and social problems can lead to sustained recovery.
Medications are used to control drug cravings and relieve severe symptoms of withdrawal. Therapy can help addicted individuals understand their behavior and motivations, develop higher self-esteem, cope with stress and address other mental health problems. Treatment may also include:
- Therapeutic communities (highly controlled, drug-free environments) or sober houses
- Outpatient programs
Many people find self-help groups for individuals (Alcoholics Anonymous, Narcotics Anonymous) as well as their family members (Al-Anon or Nar-Anon Family Groups) useful.
Drug addiction is preventable. Drug education and prevention efforts aimed at children and adolescents and involving families, schools, communities and media can be effective in reducing drug misuse.
|Risk and Protective Factors for Drug Misuse and Addiction|
|Aggressive behavior in childhood/Good self-control||Lack of parental supervision/Parental monitoring and support|
|Poor social skills/Positive relationships||Drug experimentation/Academic competence|
|Availability of drugs at school/School anti-drug policies||Community poverty/Neighborhood pride|
These 13 principles of effective drug addiction treatment were developed based on three decades of scientific research. Research shows that treatment can help drug-addicted individuals stop drug use, avoid relapse and successfully recover their lives.
- Addiction is a complex, but treatable, disease that affects brain function and behavior.
- No single treatment is appropriate for everyone.
- Treatment needs to be readily available.
- Effective treatment attends to multiple needs of the individual, not just his or her drug abuse.
- Remaining in treatment for an adequate period of time is critical.
- Counseling— individual and/or group —and other behavioral therapies are the most commonly used forms of drug abuse treatment.
- Medications are an important element of treatment for many patients, especially when combined with counseling and other behavioral therapies.
- An individual’s treatment and services plan must be assessed continually and modified as necessary to ensure it meets his or her changing needs.
- Many drug-addicted individuals also have other mental disorders.
- Medically assisted detoxification is only the first stage of addiction treatment and by itself does little to change long-term drug abuse.
- Treatment does not need to be voluntary to be effective.
- Drug use during treatment must be monitored continuously, as lapses during treatment do occur.
- Treatment programs should assess patients for the presence of HIV/AIDS, hepatitis B and C, tuberculosis and other infectious diseases, as well as provide targeted risk-reduction counseling to help patients modify or change behaviors that place them at risk of contracting or spreading infectious diseases.

How to Help a Friend or Family Member
Some suggestions to get started:
- Learn all you can about alcohol and drug misuse and addiction.
- Speak up and offer your support: talk to the person about your concerns, and offer your help and support, including your willingness to go with them and get help. Like other chronic diseases, the earlier addiction is treated, the better.
- Express love and concern: don’t wait for your loved one to “hit bottom.” You may be met with excuses, denial or anger. Be prepared to respond with specific examples of behavior that has you worried.
- Don’t expect the person to stop without help: you have heard it before – promises to cut down, stop – but, it doesn’t work. Treatment, support, and new coping skills are needed to overcome addiction to alcohol and drugs.
- Support recovery as an ongoing process: once your friend or family member is receiving treatment, or going to meetings, remain involved. Continue to show that you are concerned about his/her successful long-term recovery.
Some things you don’t want to do:
- Don’t preach: Don’t lecture, threaten, bribe, preach or moralize.
- Don’t be a martyr: Avoid emotional appeals that may only increase feelings of guilt and the compulsion to drink or use other drugs.
- Don’t cover up, lie or make excuses for his/her behavior.
- Don’t assume their responsibilities: taking over their responsibilities protects them from the consequences of their behavior.
- Don’t argue when using: avoid arguing with the person when they are using alcohol or drugs; at that point he/she can’t have a rational conversation.
- Don’t feel guilty or responsible for their behavior; it’s not your fault.
- Don’t join them: don’t try to keep up with them by drinking or using.

In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), gambling disorder is included in a new category on behavioral addictions. This reflects research findings that gambling disorder is similar to substance-related disorders in many ways. Recognizing these similarities will help people with gambling disorder get needed treatment and services, and may help others better understand the challenges.
Internet Gaming Disorder
Internet gaming disorder is included in DSM-5 in the section of disorders requiring further research. This reflects the scientific literature showing that persistent and recurrent use of Internet games, and a preoccupation with them, can result in clinically significant impairment or distress. The condition criteria do not include general use of the Internet or social media.
Caffeine Use Disorder
Caffeine intoxication and caffeine withdrawal are included in DSM-5. Caffeine use disorder, however, is in the section of DSM-5 for conditions requiring further research. While there is evidence to support this as a disorder, experts conclude it is not yet clear to what extent it is a clinically significant disorder.
