Unfortunately the evidence that vaping is as bad as smoking is mostly from faulty studies, p-hacked studies, or misinformation. Which will ultimately blow up in the face of those trying to push it. The same way "Weed will make you jump out a window" just made kids blanket distrust all "weed is bad" messaging.

I'm not arguing for or against vaping, just stating that the negative health effects from vaping appear to be rather minor. In it's pure form its just nicotine and propylene glycol. Nicotine is well studied and similar to caffeine in harm (outside the addiction) and PG is used in medical inhalers (along with almost everything else, seriously its used in food and cosmetics everywhere).
