What is Addiction – A Definition

Addiction is a complex condition, a brain disorder that is manifested by compulsive substance use despite harmful consequences. It is characterized by the inability to consistently abstain, impairment in behavioural control, craving, diminished recognition of significant problems with one’s behaviours and interpersonal relationships, and a dysfunctional emotional response. Addiction is an illness that involves changes in brain circuits involved in reward, motivation and memory.

The term addiction also refers to behaviours that are not necessarily related to substances. Behavioural addictions, such as gambling disorder, may be diagnosed when an individual engages in persistent and recurrent maladaptive behaviour related to a particular reward or reinforcement, such as money, fame or power, to the extent that it impairs personal, family, social, educational, occupational or other important areas of functioning.

Addiction is a chronic disorder with biological, psychological, social and environmental factors influencing its development and maintenance. It is often associated with co-occurring mental health disorders, including depression, anxiety, post-traumatic stress disorder, and others.

Causes of Addiction

Addiction is caused by a combination of biological, psychological, and environmental factors. Biological factors include genetics, brain chemistry, and changes in the brain structure and function. Psychological factors include environmental stress, emotional trauma, and a history of substance use.

Environmental factors can include exposure to people who use drugs, availability of drugs, and exposure to drug use in the media. Other factors, such as age and gender, may also play a role. For example, people who start using drugs at a younger age may have a higher risk of developing an addiction.

Signs and Symptoms of Addiction

Physical Symptoms

Physical signs of addiction can include changes in sleep patterns, weight, appetite, and physical coordination. People who are addicted to drugs may also experience changes in their heart rate, blood pressure, and body temperature. They may also have difficulty concentrating and may appear to be in a daze.

Behavioural Symptoms

Behavioural signs of addiction can include neglecting responsibilities, avoiding activities that were once enjoyed, and engaging in risky behaviour such as driving while under the influence of drugs or alcohol. People who are addicted to drugs may also become isolated and secretive, and may begin to engage in criminal activities such as stealing or selling drugs.

Treatment for Addiction


Medication can be used to help reduce cravings and manage withdrawal symptoms. Examples of medications used to treat addiction include methadone, buprenorphine, naltrexone, and acamprosate. These medications can help reduce cravings and the risk of relapse.

Behavioural Therapy

Behavioural therapy can help individuals identify triggers for drug use and learn new coping skills to manage cravings and avoid relapse. Examples of behavioural therapies used to treat addiction include cognitive behavioural therapy, motivational interviewing, and contingency management.

Prevention of Addiction

Education and Awareness

Educating individuals about the risks of drug use can help prevent addiction. Raising awareness of the signs and symptoms of addiction can also help individuals identify when they may need help. Providing support for individuals who are at risk of developing an addiction can also help prevent the development of the disorder.

Access to Treatment

Providing access to effective treatment for individuals who are already struggling with addiction can help reduce the risk of relapse and improve quality of life. Treatment can include medication, behavioural therapy, and support groups.
