Depressants01:28

Depressants

Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

CNS Stimulants: Psychedelic Agents

Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

An Overview of Psychoactive Drugs

Psychoactive drugs impact brain function, influencing perception, mood, consciousness, cognition, and behavior. These substances are grouped based on their effects and the mechanisms by which they act.
Stimulants such as cocaine, amphetamines, and nicotine enhance brain activity, leading to increased alertness, attention, and energy. These drugs typically raise heart rate, blood pressure, and body temperature. While they can induce feelings of euphoria, their misuse can result in severe health...

Hallucinogens and Psychedelics

Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains delta-9-tetrahydrocannabinol (THC)...
Drugs Acting on Autonomic Ganglia: Stimulants01:23

Drugs Acting on Autonomic Ganglia: Stimulants


Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
Sedatives and Hypnotics Drugs: Barbiturates01:20

Sedatives and Hypnotics Drugs: Barbiturates

Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect. A key...

Summary

This review synthesizes knowledge on club drugs like MDMA and LSD, detailing their effects, risks, and treatment. It aims to equip health professionals with essential information for diagnosing and managing club drug abuse.

Area of Science:

  • Pharmacology
  • Toxicology
  • Public Health

Background:

  • Club drugs, including MDMA, methamphetamine, LSD, ketamine, GHB, and flunitrazepam, are frequently used by young adults in recreational settings.
  • These substances exhibit diverse psychotropic effects, varying toxicity, dependence potential, and long-term adverse health consequences.
  • Club drug use is often underdiagnosed due to detection challenges and a lack of familiarity among healthcare providers.

Purpose of the Study:

  • To conduct a systematic literature review on club drugs.
  • To synthesize current knowledge regarding the epidemiology, mechanisms of action, detection, adverse reactions, and treatment of club drug abuse.
  • To establish a Portuguese-language knowledge base for healthcare professionals dealing with club drug abuse.

Main Methods:
