• The science isn’t fully decided on vapes - AFAIK the PG/VG and nicotine are relatively harmless (though nicotine does carry some heart/stroke risks) but the flavours are generally only tested for safety when taken orally, not when atomised and inhaled. Flavourless vape juice is therefore probably safe, though hardly anybody sells it, it’s kinda unpleasant, and it does still carry some health risks.

    • Let me just rephrase what you said. Instead of “the science isn’t fully decided”, which paints an incorrect picture, let’s rather say “of everything they’ve tested in a typical legal vape, everything is essentially harmless. Some of the components haven’t been tested.”

      Saying “the science isn’t fully decided” implies “eh, maybe it’s dangerous, maybe it’s not, 50/50”. That’s not at all the case. It’s almost certainly all harmless. Just very addictive.

      • That’s not true. “The science isn’t fully decided” means that long-terms effects are extremely hard to measure, it literally takes decades. The amount of liquids of different flavors is so big that you can’t realistically test them all. Different flavors require different chemicals, you can get the same taste with different chemicals too. Yes, basic liquid is probably less harmful than cigarettes, but even for that there’s not enough data to say that this is a scientific fact.
