Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

305
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

244
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...

Vaporization01:18

Vaporization

34.7K
The physical form of a substance changes by changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. For vaporization to occur, kinetic energy must be greater than the intermolecular forces that keep molecules bonded. The amount of energy needed to vaporize a quantity of liquid at a given pressure and a constant temperature is called the heat of vaporization. When...

An Overview of Psychoactive Drugs

258
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...

Drug Regulation01:25

Drug Regulation

1.4K
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

230
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...

Area of Science:

  • Public Health
  • Substance Use Research
  • Retail Environment Studies

Background:

  • Kratom, a Southeast Asian plant with stimulant and opioid-like effects, is legal in most US states despite DEA concern.
  • Limited data exists on kratom product availability in retail settings.
  • Vape shops are increasingly recognized as potential points of sale for kratom.

Purpose of the Study:

  • To determine kratom availability in California vape shops.
  • To assess vape shop compliance with a kratom sales ban in San Diego.
  • To explore factors influencing kratom availability in retail environments.

Main Methods:

  • A random sample of 614 vape shops across California was surveyed in summer 2019.
  • Availability was assessed in relation to proximity to colleges and store type (vape-only vs. vape-and-smoke).
  • Logistic regression analyzed factors associated with kratom availability.

Main Results:

  • Kratom was available in 62.4% of observed vape shops.
  • Availability was significantly higher in vape-and-smoke shops (81.1%) compared to vape-only shops (11.5%).
  • Kratom availability did not vary based on proximity to colleges, but 46.2% of San Diego stores sold it despite a ban.

Conclusions:

  • Kratom is broadly available in California vape shops, particularly those selling other tobacco products.
  • Findings suggest a need for research on dual-use with tobacco and kratom marketing.
  • The study underscores the potential role of tobacco retail licensing in regulating kratom sales.
