What are Psychoactive Drugs | Psychoactive Drugs Definition

Psychoactive, also called psychotropic, is a term that is applied to chemical substances that change a person’s mental state by affecting the way the brain and nervous system work. This can lead to intoxication, which is often the main reason people choose to take psychoactive drugs. The changes in brain function experienced by people who use psychoactive substances affect their perceptions, moods, and/or consciousness.


Psychoactive substances are found in a number of medications as well as in alcohol, illegal and recreational drugs, and some plants and even animals. Alcohol and caffeine are psychoactive drugs that people most commonly use to alter their mental state. Usually, people decide when and how they want to use psychoactive drugs. A common example of this is the date-rape drug Rohypnol, which is illegal in the U.S.

You should also be aware that taking prescribed psychoactive drugs in ways other than intended, for example, taking drugs that have been prescribed for someone else, even if they have been given to you, is illegal.

Groups of psychoactive drugs include stimulants, depressants, narcotics (opioids), hallucinogens, and marijuana (cannabis).

Natural substances, such as hallucinogenic mushrooms and cacti, and the leaves, flowers, and buds of certain plants may also be psychoactive. Some people think that, because these substances occur naturally, they are less harmful than manufactured drugs. However, that is not the case.

The reason for this is because the person taking the substance has no control over the strength of the plant’s psychoactive substance or toxicity, as there is in manufactured drugs. A drug or medication that’s termed “psychoactive” isn’t necessarily addictive, although many are.
