Dictionary

A psychoactive drug is a substance that has effects on the brain and alters an individual’s mood, perception, or consciousness. Psychoactive drugs can be classified into several categories: stimulants, depressants, psychedelics, and opioids. Some common examples of psychoactive drugs include caffeine, alcohol, nicotine, marijuana, cocaine, ecstasy, and prescription painkillers.

Psychoactive drugs can have therapeutic uses, such as the treatment of mental health disorders and chronic pain, but they also have the potential to be abused and lead to addiction. The effects of psychoactive drugs vary depending on the type of drug, the dose, and the individual’s biology and mental health.
