psychoactive compounds

Psychoactive compounds are chemicals that affect the brain and alter mood, perception, consciousness, or behavior. They work by interacting with neurotransmitters—the brain's chemical messengers—modifying how nerve cells communicate. This can lead to feelings of euphoria, relaxation, altered senses, or, in some cases, hallucinations. Common examples include caffeine, found in coffee; alcohol; nicotine; and drugs like cannabis, cocaine, or LSD. These compounds vary in potency and effects, and their use can have both short-term impacts and long-term health implications.
