Are cannabis vapes safe?
Vapes cut combustion products by >90 % vs smoking — easier on the lungs. But not risk-free: illegal cartridges (additives like vitamin E acetate, EVALI 2019) caused lung failure. Safe: certified dry-flower vaporizers or tested legal cartridges.
Key facts
- –90 % combustion products
- EVALI 2019: illegal cartridges
- Dry-flower vape safest
- Only certified cartridges
Detailed answer
Vaporizers heat cannabis to 180–210 °C (below combustion), releasing cannabinoids/terpenes but little tar, CO or PAHs. Studies (Abrams, Loflin) show far fewer respiratory symptoms. But the 2019 EVALI crisis (USA) with >2,800 lung-failure cases came from illegal cartridges with vitamin E acetate. Safety rules: (1) dry-flower vaporizer (Volcano, Mighty) safer than cartridges; (2) cartridges only with batch certificate from legal market; (3) never unidentified oils from the black market; (4) don't overheat batteries.
