Weed vapes probably sending a toxic gas to your lungs, study finds

ver since vaping overtook traditional smoking as the culturally preferred method of inhaling nicotine and marijuana, vaping proponents have vigorously challenged the claims of various health risks associated with e-cigarettes. In particular, critics have noted — and advocates have struggled to defend — the rising victim tally for EVALI, a disease with an acronym that speaks for itself: “e-cigarette or vaping product use-associated lung injury.” The challenge, for health experts, has been acquiring precise biochemical information about the effect of vaping on the body.vaping-cannabinoid-acetates-leads-to-ketene-formation
