Hallucinogens and Psychedelics

248
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...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

310
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...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

358
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.

Stimulants01:29

Stimulants

273
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...

Summary
This summary is machine-generated.

Ingesting 10mg of delta-9-tetrahydrocannabinol (THC) via edibles before exercise did not impact physiological responses or performance in regular cannabis users. This study found THC to be neither performance-enhancing nor performance-reducing in this context.

Area of Science:

  • Exercise Physiology
  • Cannabinoid Science
  • Sports Nutrition

Background:

  • Growing public and scientific interest in cannabis and delta-9-tetrahydrocannabinol (THC) effects on exercise performance.
  • Lack of recent, up-to-date studies investigating these influences.

Purpose of the Study:

  • To test the hypothesis that edible marijuana negatively affects physiological responses and performance during exercise.
  • To provide current data on the impact of THC on exercise.

Main Methods:

  • 10 healthy, habitual exercisers and regular cannabis users ingested either 10mg THC edible marijuana or placebo before two separate exercise sessions.
  • Cardio-respiratory responses were measured during graded cycle ergometry.
  • Functional Threshold Power (FTP20) and sprint test performance were assessed.

Main Results:

  • Edible marijuana increased THC levels and induced psychoactive effects but did not alter cardio-respiratory responses during exercise.
  • No significant differences were observed in FTP20 or peak sprint power output between THC and placebo conditions.
  • THC ingestion did not ergogenically or ergolytically affect exercise performance.

Conclusions:

  • 10mg of THC from edible marijuana has minimal impact on physiological responses to standardized exercise in regular users.
  • THC did not enhance or impair exercise performance in this specific population and dosage.
  • Further research may explore different dosages or consumption methods.
