The FDA analyzed 19 cartridges made by Smoking Everywhere and NJOY. The agency found detectable levels of tobacco-specific nitrosamines--which are known human carcinogens--in half the samples. Most samples also contained impurities known to be toxic to humans, such as anabasine, myosmine, and beta-nicotyrine. One cartridge contained 1% diethylene glycol, a toxic component of antifreeze. …
