What Are the Common Types of Psychoactive Substances?
Psychoactive substances can be classified into several categories based on their effects on the central nervous system:
Depressants: These substances slow down brain activity and can induce relaxation or sedation. Examples include alcohol, barbiturates, and benzodiazepines. Stimulants: These increase brain activity, leading to heightened alertness and energy. Common stimulants include caffeine, nicotine, and cocaine. Hallucinogens: These alter perception and can cause visual or auditory hallucinations. LSD and psilocybin are well-known hallucinogens. Opioids: Known for their pain-relieving properties, opioids like morphine and heroin can also produce euphoria. Cannabinoids: Substances like THC in cannabis can affect mood, perception, and coordination.
