fwiw, this is what perplexity.ai says on the subject:
there is research suggesting that vaporizing cannabis may be less harmful than smoking it, particularly in terms of respiratory effects. However, it's important to note that vaping cannabis still carries risks and is not without potential negative health consequences.
Respiratory Effects
Vaporizing cannabis has been found to reduce exposure to several harmful compounds compared to smoking:
- It produces fewer toxic pyrolytic compounds and by-products, such as carcinogenic polynuclear aromatic hydrocarbons, benzene, and toluene
- It reduces exposure to carbon monoxide, potentially lowering the risk of respiratory hazards
A small non-randomized trial reported significantly improved respiratory symptoms and forced vital capacity among cannabis smokers who switched to vaping for 30 days.
Additionally, a cross-sectional study found that vaporizer users were 40% less likely to report respiratory effects like cough, phlegm, and chest tightness compared to those who smoked cannabis.
Comparative Studies
Research comparing vaping and smoking cannabis has yielded mixed results:
- A study at Johns Hopkins University found that vaping marijuana had stronger effects on cognitive and motor skills than smoking it, raising safety concerns about activities like driving
- Vaping cannabis resulted in higher THC blood levels compared to smoking the same dose, potentially leading to more pronounced drug effects
Health Considerations
While vaping may reduce some risks associated with smoking cannabis, it's not without its own health concerns:
- Vaping doesn't address issues related to dependence, impaired driving, or potential brain damage among heavy adolescent users.
- Some research suggests that vaping marijuana may be associated with more symptoms of lung damage than e-cigarettes or smoking cigarettes or marijuana alone
It's important to note that more long-term studies are needed to fully understand the health implications of vaping cannabis compared to smoking it. While current evidence suggests some potential benefits in terms of respiratory health, vaping still carries risks and should not be considered completely safe.
