Sense: adjective/1
Mind-altering is the broadest term for substances that change mental state by working on the brain. Psychoactive is the clinical, neutral term used in medical and scientific writing — it describes any substance that alters brain function, from caffeine to prescription antidepressants. Psychedelic is more specific, usually referring to substances like LSD or psilocybin that produce vivid perceptual changes and expanded awareness, often tied to the 1960s counterculture. Hallucinogenic focuses on the effect of causing hallucinations — seeing or hearing things that are not present. Intoxicating is broader still, covering alcohol and drugs that reduce self-control, coordination, or awareness. For example, a doctor might warn about psychoactive medication, a historian might describe psychedelic rituals in ancient Mexico, and a police report might mention intoxicating levels of alcohol.
Common collocations
Etymology
A compound word formed from 'mind' (from Old English gemynd, meaning memory, thought, or consciousness) and 'altering' (the present participle of 'alter', from Latin alterare, meaning to make different or change). The term entered common use in the mid-20th century, especially during the 1960s when researchers and the public began discussing the effects of psychedelic substances on human consciousness.
