Hallucinogens and Psychedelics

527
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.

CNS Stimulants: Psychedelic Agents

586
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

487
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...

Altered States of Awareness

923
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Psychosurgery

1.1K
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Psychodynamic Therapy01:29

Psychodynamic Therapy

409
Psychodynamic therapies emphasize the exploration of unconscious processes and early childhood experiences as fundamental contributors to psychological difficulties. These therapies, deeply rooted in Freud's psychoanalytic theory, aim to uncover and resolve unconscious conflicts, granting individuals insights that promote emotional and behavioral healing. Contemporary psychodynamic approaches have evolved, integrating a broader range of influences and methodologies while still valuing the...

  • Limited data exists on psychedelics' impact on criminal behavior.

Purpose of the Study:

  • To inform forensic practitioners about psychedelic substances.
  • To review research on psychedelics and criminal behavior.
  • To provide assessment strategies for psychedelic use in forensic contexts.

Main Methods:

Main Results:

  • Early research (Leary, 1960s) did not clearly link psychedelic-assisted therapy to reduced recidivism.
  • Recent studies suggest a potential decrease in interpersonal violence associated with psychedelic use.
  • Forensic psychiatrists need awareness of these evolving findings.

Conclusions:

  • Psychedelic research is experiencing a renaissance, impacting psychiatric and forensic fields.
  • The relationship between psychedelic use and criminal behavior requires further investigation.
  • Forensic evaluators should be prepared to assess psychedelic use and its implications.
