Stimulants01:29

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

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)...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its effects by...

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 Drugs01:28

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...
Effects of Chemicals: Overview01:27

Effects of Chemicals: Overview

Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...

Area of Science:

  • Psychopharmacology
  • Addiction Research
  • Toxicology

Background:

  • Mephedrone, a synthetic stimulant, has gained popularity within recreational drug scenes.
  • Understanding its use patterns and dependence potential is crucial for public health.
  • Limited data exists on the subjective effects and abuse liability of mephedrone.

Purpose of the Study:

  • To evaluate mephedrone's usage patterns, subjective effects, and dependence potential.
  • To correlate self-reported use with objective toxicological findings.
  • To assess the risk of abuse and health implications associated with mephedrone.

Main Methods:

  • Cross-sectional study involving 100 mephedrone users from the UK dance music scene.
  • Structured telephone interviews to assess drug use patterns, acute/after effects, and DSM-IV dependence criteria.
  • Gas chromatography-mass spectrometry urinalysis to confirm recent mephedrone consumption.

Main Results:

  • Mephedrone use produced typical stimulant effects (euphoria, increased concentration, insomnia).
  • 30% of users potentially met DSM-IV dependence criteria, with 47% reporting compulsive use over consecutive days.
  • Urine toxicology confirmed recent mephedrone use in all tested participants.

Conclusions:

  • Mephedrone exhibits a high liability for abuse and poses significant health risks.
  • Key dependence symptoms include increased tolerance, impaired control, and a strong compulsion to use.
  • Urgent public health strategies are needed to address the risks associated with mephedrone.
