Drug Addiction: Definitions and Types

Generally, drug addiction is seen as a compulsive behaviour that compels patients to take psychoactive or not prescribed substances in order to function normally. When it comes to defining drug addiction, we can go through different recognised and accepted definitions.

According to the world health organisation (WHO), “Drug addiction is a state of periodic or chronic intoxication produced by the repeated consumption of a drug (natural or synthetic).”

According to the American Academy of Pain Medicine, the American Pain Society, and the American Society of Addiction Medicine, “Addiction is a primary, chronic, neurobiologic disease, with genetic, psychosocial, and environmental factors influencing its development and manifestations. It is characterized by behaviours that include one or more of the following: impaired control over drug use, compulsive use, continued use despite harm, and craving.”

According to professor Nils Bejerot, “An emotional fixation (sentiment) acquired through learning, which intermittently or continually expresses itself in purposeful, stereotyped behaviour with the character and force of a natural drive, aiming at a specific pleasure or the avoidance of a specific discomfort.”

Below mentioned are some of the common types of drug addiction. Some of them include:

  • Alcohol dependence
  • Opioid dependence
  • Sedative, hypnotic, or anxiolytic dependence
  • Cocaine dependence
  • Cannabis dependence
  • Amphetamine dependence (or amphetamine-like)
  • Hallucinogen dependence
