Hallucinogens and Psychedelics

483
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...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

595
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

366
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

A positive marijuana toxicology screen in trauma patients is not linked to worse mortality or longer hospital stays. Further research is needed to understand marijuana

Area of Science:

  • Trauma Care
  • Toxicology
  • Public Health

Background:

  • Trauma patients often undergo toxicology screening.
  • The impact of marijuana use on trauma outcomes requires clarification.

Purpose of the Study:

  • To investigate the association between positive marijuana toxicology screens and outcomes in adult trauma patients.
  • To determine if marijuana use affects mortality, injury severity, or hospital length of stay.

Main Methods:

  • Retrospective analysis of adult trauma patients from a Level II trauma registry.
  • Inclusion criteria: available marijuana toxicology results; exclusion criteria: positive polysubstance screen.
  • Key endpoints: mortality, injury severity score, length of stay, Glasgow Coma Scale, blood requirements.

Main Results:

  • No significant difference in mortality or length of stay between marijuana-positive and marijuana-negative patients.
  • Age was a significant factor, with younger patients (<55 years) more likely to suffer major trauma.
  • Older patients (≥55 years) showed differences in blood pressure and heart rate upon presentation.

Conclusions:

  • A positive marijuana screen in trauma patients does not correlate with increased mortality or hospital length of stay.
  • These findings suggest marijuana use alone may not worsen immediate trauma outcomes.
  • Further investigation into the nuanced effects of marijuana on trauma patient recovery is warranted.
