What Is a Psychoactive Drug?

A psychoactive drug is a substance that affects the central nervous system and alters brain function. A psychoactive drug typically results in a temporary change in perception, consciousness, behaviour, and mood. A psychoactive drug can either be a prescribed medication or a substance that is used recreationally. Many psychoactive drugs are known to be habit forming and can cause dependence or addiction in certain individuals. Not all people who use a psychoactive drug however, will become dependent.

History of Psychoactive Drugs

Psychoactive substances have been used for at least 10,000 years. In early history, psychoactive drugs were typically plant-based and often used for medicinal purposes. For example, chewing of the betel nut in Thailand dates back over 10,000 years ago, and chewing of coca leaves dates back at least 8,000 years amongst cultures in Peru. Native Americans were using tobacco long before European contact, and opiates made from the poppy plant have been used to control pain as early as 7,000 years ago.

Hallucinogens have been used for at least 2,000 years by various indigenous cultures. The use of psilocybin mushrooms dates back to the Mayans, and Native American cultures have used peyote in religious ceremonies for centuries.

The use of alcohol has been displayed by countless cultures since time began. In the 1840s, hashish was used to treat mental disorders at the Bicetre in France. Psychoactive drugs were introduced in medicine as early as the late-1700s. Since then, prescribed psychoactive drug use has continued to increase into what is seen today with modern medicine.

Types

Psychoactive drugs are categorised into four different classes. These include:

  • Depressants: This includes substances such as alcohol, benzodiazepines, and barbiturates. Depressants invoke effects such as relaxation, reduced anxiety, and sleep.
  • Stimulants: This includes substances such as amphetamines, cocaine, nicotine, caffeine, and ecstasy. Stimulants arouse feelings of alertness, euphoria, wellbeing, increased confidence, and hallucinations (typically with ecstasy).
  • Opiates: This includes substances such as heroin, morphine, certain prescription painkillers, and opium. Opiates offer feelings of euphoria, wellbeing, and as a pain reliever.
  • Psychedelics: This includes substances such as LSD, psilocybin mushrooms, marijuana, spice, and PCP. Psychedelics evoke hallucinations, feelings of wellbeing, euphoria, relaxation, and altered perceptions.
