Adverse Effects of Psychoactive Substances

Effects of Illicit Drugs

  • Opiates: High risk of dependency, craving, and significant long-term physical harm. Opiates contribute to significant societal issues and high mortality rates.

  • Cocaine: Leads to potential dependence, bingeing, and long-term health risks.

  • Ecstasy (MDMA): Generally lower physical dependence but potential societal risks; research suggests benefits in PTSD treatment.

  • Amphetamines: Moderate risk for both physical health and societal impacts.

  • Ketamine: Craving, bingeing, and long-term effects are significant concerns.

Effects of Non-Illicit Drugs

  • Alcohol: Major social risk factor, associated with bingeing and contributing to approximately 2.5 million deaths globally each year.

  • Tobacco: Continues to be a leading cause of dependency, with a mortality rate double that of alcohol.

  • Prescription Analgesics: Present a high risk of dependency and long-term harm when misused.
