Well my point was that they were originally intended to reduce nicotine addiction, but they are actually increasing nicotine addiction due to being perceived as safe alternative to cigarettes by teens. I suspect that legalizing drugs such that they are "cleaner and dosing more predictable" (aka "more safe") would inevitably cause an increase in usage and therefore addiction.
Sorry, I had no idea what a Juul was, and Google indicated it was a brand of e-cig. Only included the comment because I assumed other non-smokers would have no idea.
No. When you read the patents you'll realize that Jull vapes were designed mimic the psychopharmacology of cigarettes, which everyone knows are pretty damn addictive. Regular vapes have a different chemistry. You hope that Juul gets sued out of existence and that the FDA rouses itself to action.
