Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

649
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.

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

728
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...

Stimulants01:29

Stimulants

802
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 Psychedelics01:27

Hallucinogens and Psychedelics

561
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...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

360
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Cognitive Development During Adolescence01:18

Cognitive Development During Adolescence

447
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

Area of Science:

  • Adolescent development
  • Cannabis use and mental health
  • Psychosocial indicators

Background:

  • Adolescence is a critical developmental stage.
  • Limited data exists on dose-dependent cannabis use effects on adolescent psychosocial development, especially for infrequent users.
  • Understanding these associations is crucial for targeted interventions.

Purpose of the Study:

  • To examine the dose-dependent relationship between cannabis use frequency and psychosocial development indicators in adolescents.
  • To identify specific adverse outcomes associated with varying levels of cannabis consumption.
  • To inform public health strategies regarding adolescent cannabis use.

Main Methods:

  • Cross-sectional study utilizing a nationally representative sample of US 8th, 10th, and 12th graders (2018-2022).
  • Participants categorized into nonuse, noncurrent, monthly, weekly, and near-daily cannabis use groups.
  • Demographically adjusted odds ratios and effect sizes calculated for psychosocial indicators.

Main Results:

  • Over 26% of 162,532 students reported cannabis use.
  • Noncurrent and monthly cannabis users showed increased odds of poor academic performance, impulsivity, self-regulation issues, and adverse emotional states compared to nonusers.
  • A dose-response trend was observed for most adverse psychosocial outcomes, with younger users (<16 years) exhibiting greater susceptibility.

Conclusions:

  • Dose-dependent associations between cannabis use frequency and adverse academic/emotional functioning are evident in adolescents, even with monthly use.
  • These findings underscore the importance of routine cannabis use screening in adolescent healthcare.
  • Early intervention and prevention efforts are critical to mitigate negative psychosocial impacts.
