"It's not out of line to say there's a potential health risk in marijuana smoke, and there's not nearly enough research," said Robert Nishida, a U of A post-doctoral fellow and co-lead on the study. Among the billions of particles found in a single puff of cannabis smoke, Nishida's team observed 2,575 chemical compounds and was able to identify 536. Of those, 110 are known to be toxic, whether they be carcinogenic, mutagenic, or teratogenic, which are chemicals that can interfere with the development of the embryo or fetus. Read more...
