Summary
Cannabis vaporisation has risks, with some devices like metered dose inhalers posing lower dangers. Improved education on cannabis vaping products and risks is crucial for public health and harm reduction.
Area of Science:
- Public Health
- Cannabis Research
- Harm Reduction
Background:
- Vaporisation is a popular cannabis administration method with increasing public interest.
- Inconsistent terminology and safety concerns necessitate improved knowledge on cannabis vaping.
- Understanding risks associated with various cannabis vaping products is critical.
Purpose of the Study:
- To review common terminology, regulatory status, products, and device types for cannabis vaporisation.
- To address the confusion and knowledge gaps surrounding cannabis vaping.
- To inform public health strategies and healthcare professional education.
Main Methods:
- Conducted a comprehensive review of cannabis vaporisation literature.
- Analyzed common terminology, regulatory landscape, and available products.
- Categorized cannabis vaporisation devices into distinct types.
Main Results:
- Identified nine distinct types of cannabis vaporisation devices.
- Vaporisation can reduce respiratory risks compared to combustion, but safety varies by product and device.
- Metered dose inhalers and dried product vaporisers show lower safety risks due to reduced toxin exposure and lower THC potency.
Conclusions:
- Accurate health education is vital for promoting lower-risk cannabis use as vaping popularity grows.
- The lack of understanding regarding risk differences among cannabis vaporisation devices is a missed harm reduction opportunity.
- Enhanced education for the public and healthcare professionals on cannabis vaporisation devices and risks, alongside improved labeling, is recommended.

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...

01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
281
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.

02:34Vapor Pressure
35.0K
When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules move randomly about, they will occasionally collide with the surface of the condensed phase, and in some cases, these collisions will result in the molecules re-entering the condensed phase. The change from the gas phase to the liquid is called condensation. When the rate of condensation becomes equal to the rate of vaporization, neither the amount of the liquid nor the amount of the vapor...

01:18Vaporization
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...

01:20Inhalational Anesthetics: Overview
299
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

01:01Distillation: Vapor–Liquid Equilibria
2.8K
Distillation is a separation technique that takes advantage of the boiling point properties of disparate elements in a mixture. To perform distillation, we begin by heating a miscible mixture of two liquids with a significant difference in boiling points (at least 20°C). As the solution heats up and reaches the bubble point of the more volatile component, some molecules of the more volatile component transition into the gas phase and travel upward into the condenser, which is a glass tube...
