Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

1.1K
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 Cannabinoids

1.4K
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...

Drug Dosing: Obese Patients01:21

Drug Dosing: Obese Patients

353
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Drug Control Governance: Regulatory Bodies and Their Impact01:03

Drug Control Governance: Regulatory Bodies and Their Impact

685
Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...

Hallucinogens and Psychedelics01:27

Hallucinogens and Psychedelics

1.0K
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...

Overview of Metabolism

25.5K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Area of Science:

  • Cannabis research
  • Human physiology
  • Metabolic regulation

Background:

  • Acute marijuana use is linked to increased appetite, often called "the munchies."
  • Some studies suggest marijuana may increase body mass index in patients with HIV and cancer, though weight gain may not be clinically significant.
  • Epidemiological data in the general population show marijuana users tend to have lower body mass indices than nonusers.

Purpose of the Study:

  • To explore the complex relationship between marijuana use and body weight.
  • To investigate potential explanations for paradoxical findings regarding marijuana's effect on body mass index.
  • To examine if marijuana acts as a metabolic regulator based on initial weight status.

Main Methods:

  • Review of existing literature on marijuana use and body weight.
  • Analysis of epidemiological studies in the general population.
  • Consideration of potential confounding factors in marijuana and body weight research.

Main Results:

  • Acute marijuana use generally stimulates appetite, particularly in low-weight individuals.
  • Large-scale studies indicate marijuana users often have lower body mass indices than nonusers.
  • Potential confounding factors include acute vs. chronic use, co-occurring substance use, and reward pathway competition.

Conclusions:

  • The relationship between marijuana and body weight is complex and requires further research.
  • Marijuana's effect on body weight may depend on factors like duration of use and individual weight status.
  • Further investigation is needed to clarify marijuana's role as a potential metabolic regulatory substance.
