Psychoactive means pertaining to effects on mood, thinking, and behavior.


In the psychology context, "psychoactive" refers to substances or drugs that have the ability to affect mental processes, cognition, mood, perception, or behavior by acting on the central nervous system. These substances alter brain chemistry and neurotransmitter activity, leading to changes in consciousness or psychological functioning. Psychoactive drugs can produce a wide range of effects, including euphoria, relaxation, altered sensory perception, heightened alertness, or altered states of consciousness. They can be categorized into various classes based on their pharmacological effects, such as stimulants, depressants, hallucinogens, and opioids.

Treatment and Risks

  • Treatment: Psychoactive substances are sometimes used in clinical settings as part of pharmacological interventions for mental health disorders. For example, antidepressants, antipsychotics, and anxiolytics are commonly prescribed to manage symptoms of depression, psychosis, and anxiety disorders. However, the use of psychoactive drugs in treatment requires careful monitoring and consideration of potential risks, including dependence, tolerance, withdrawal symptoms, and adverse reactions.

Prolonged use of certain drugs can lead to addiction, cognitive impairment, psychiatric disorders, and other adverse consequences. Additionally, psychoactive substances may interact with other medications or underlying medical conditions, potentially exacerbating symptoms or causing harmful effects. Vulnerable populations, such as adolescents, pregnant women, and individuals with pre-existing mental health conditions, may be particularly susceptible to the negative effects of psychoactive substances.
