CNS Stimulants: Psychedelic Agents

1.1K
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...

Hallucinogens and Psychedelics

1.1K
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...

Combined Effects of Drugs: Synergism

6.2K
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

Drug Abuse and Addiction: Pharmacological Phenomena

1.6K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

1.5K
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...

An Overview of Psychoactive Drugs

866
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...

    Summary
    This summary is machine-generated.

    Recreational drug use, particularly cocaine, impairs source memory, affecting the ability to recall information context. This can hinder everyday tasks requiring memory for crucial details and learning.

    Area of Science:

    • Neuroscience
    • Cognitive Psychology

    Background:

    • Source memory, the ability to recall contextual details of an experience, is crucial for everyday cognition.
    • Recreational illicit drug use is prevalent, yet its specific impact on source memory remains incompletely understood.

    Purpose of the Study:

    • To investigate the effects of recreational drug use, specifically ecstasy and polydrug use, on source memory performance.
    • To examine how drug use patterns correlate with deficits in recalling the format, location, and temporal position of presented information.

    Main Methods:

    • A source memory task was administered to 62 ecstasy/polydrug users and 75 non-users.
    • Participants identified previously presented words and recalled their presentation format (case), location, and temporal order.

    Main Results:

    • Ecstasy/polydrug users exhibited a more liberal decision criterion for word recognition but showed deficits in recalling presentation format (case).
    • Female users performed worse than non-users in determining the list order of words.
    • Higher frequency of current cocaine use was negatively associated with performance on list and case source memory tasks.

    Conclusions:

    • Recreational drug use, particularly cocaine, can impair source memory, impacting the ability to recall contextual information.
    • Individuals with frequent cocaine use may face challenges in everyday tasks requiring memory for crucial information sources or contextual learning aids.
