[character happily points at a green cube] Green cubes are not dangerous for your health, they're just green cubes
[the character is suddenly drowned under a mass of green cubes falling from above]
[a researcher looks smugly at the previous panel] Seems a million green cubes falling on top of you is not healthy… This we have conclusively proven that green cubes are bad for your health
The thing with vapes ia that the user of them can't have one vape, by the nature of addiction, they necessarily are consuming ten million of those. Just like one cigarette is not dangerous at all, but smoking 500 of those means you're addicted and will die of lung cancer
Side note, it's near impossible yo find any info whatsoever on what 1-5 cigarettes a week do to your health. I used to casually smoke roughly that amount and wanted to know what the risk was but I genuinely couldn't find even a single study.
You seems to be lucky with addiction, but it's so incredibly rare, research into that might be impossible without killing a bunch of people, making them addicted to nicotine. Anecdotally, all my friends who were casually smoking "only at parties" or no more than a sig a day, either stopped, or started smoking for real.
I have super debilitating ADHD, and my lack of tendency to form addictions is just about the only advantage, but I'll take it gladly.
The point was like, vapes contain only 4 food-safe ingridients, should be obvious that by it's nature it must be at least somewhat safer than burning tobacco which releases over a 100 obviously toxic elements. Nobody was ever claiming that vape is completely safe. But big tobacco doesn't like competition, so they've funded a lot of sham research where scientists would e.g. jam a vape into a smoke analyzer and run it full blast until the cotton catches fire, the coils melt or batteries blow up, disregarding that it's physically impossible to inhale the resulting mess. Then they poisoned people with IQOS-like products and ran advertising campaigns for JUUL(partly owned by PM) explicitly aimed for children. Then paid a bunch of news outlets to run stories about it but shift the blame at vapes. That aside from pretty blatant lobbying as cigarette tax makes a pretty hefty government income in a lot of countries.
