There is also pretty decent evidence that it's not that dangerous: https://gwern.net/nicotine https://gwern.net/nicotine -edit- that write up is almost exclusively for adults. The affects on teens and children, with developing brains etc., is much less clear and if nothing else the precautionary principle would probably say that it's a bad idea. But for adults, I'm personally convinced that the balance of evidence is that nicotine itself is not particularly harmful when consumed in reasonable amounts. -edit- also realized that I linked to the same article that the top level comment linked. Considering that that post includes dozens of journal articles, linking one single research article without addressing any of the contrary ones isn't particularly useful.
