PSYCHOACTIVE DRUGS Meaning and
Definition
-
Psychoactive drugs, also known as psychotropic substances, are substances that affect the functioning of the central nervous system (CNS), altering one's perception, mood, consciousness, cognition, or behavior. These drugs have the ability to cross the blood-brain barrier and directly impact brain chemistry, leading to changes in mental processes and behavior. Psychoactive drugs can be naturally occurring or synthetically produced, and they are classified into various categories based on their effects.
One category is stimulants, which increase alertness, energy, and attention, such as amphetamines or cocaine. Another category is depressants, which slow down brain activity, promoting relaxation and sedation, such as alcohol or benzodiazepines. Hallucinogens, also called psychedelic drugs, alter perception, mood, and thought processes, causing hallucinations or altered states of consciousness, as seen with LSD or psilocybin mushrooms. Opioids, including prescription painkillers or heroin, are in a separate category and primarily act on the brain's opioid receptors, relieving pain and producing euphoria.
The use of psychoactive drugs can lead to various short-term and long-term effects, including addiction, dependence, tolerance, withdrawal symptoms, impaired cognitive function, mood disorders, and physical health problems. Additionally, the illegitimate or non-prescription use of psychoactive drugs is often considered illegal and can lead to legal consequences.
It is crucial to note that while some psychoactive drugs have legitimate medical uses when prescribed by a healthcare professional, their misuse or non-medical use poses significant risks to individuals' physical and mental well-being.

Etymology of PSYCHOACTIVE DRUGS
The word "psychoactive" is derived from two Greek words: "psyche", meaning mind or soul, and "active", meaning capable of producing an effect. "Psyche" is also the root word for psychology, referring to the study of the mind. Therefore, "psychoactive" refers to substances or chemicals that directly affect the mind or produce an impact on brain function.
The term "drugs" has its origin in Old French, derived from the Latin word "droga", which means medicine or substance that has an effect on the body. It has evolved in modern English to refer to any substance, legal or illegal, that affects the body's physiological processes.
Thus, when combined, "psychoactive drugs" refer to any substances or chemicals that have an impact on the mind or alter brain function. These substances can cause changes in perception, mood, cognition, consciousness, or behavior.
