The Drug Wheel

Categorising and classifying drugs has become more complex in the last 20 years, with an increase in new psychoactive substances.

This ever-expanding drug landscape has resulted in the development of The Drug Wheel, which classifies drugs as part of the following 7 general categories: Stimulants, Depressants, Cannabinoids, Psychedelics, Opioids, Dissociatives and Empathogens.
