I always felt like there is some propaganda going on in the other direction too. I see people online saying e cigarettes are just as bad and cause cancer just like cigarettes everywhere, despite the fact that except for vitamine e acetate in some illegal thc cartridges there arent really any risks found related to it anywhere near to the levels of smoking.
Im not sure about the exact ratio, but i agree that the risks are not well researched enough and so we should be cautious (and of course nicotine itself is harmful for the developing brain). The best alternative in my opinion would be tobacco free nicotine pouches that are only harmful for dental health.
