The Drugs Wheel
Different psychoactive substances have different actions and effects on the mind and body. The Drugs Wheel is a simple model that can be used to better understand the categories of drugs and their effects. It does not aim to list every available drug or their effects. The outer ring indicates the category of drug. The middle ring includes some of the effects people may experience from using drugs in that category. The inner ring provides examples of drugs that fall into that category.
