Agreed, there's a lot of FUD, but a lot of it is coming from sources that give me a lot of hesitation to doubt (lots of public health leaders, tobacco control groups, WHO people)
I understand alcohol or weed is more harmful than vaping, I'm personally just interested in cigarettes as that seems to be the replacement part, I'm not sure someone would quit drinking or smoking weed and replace with vaping
Edit: I know you pointed me to a solid report in an earlier comment, any additional ones? There are huge numbers of reports on tobacco in general and it's easy to find 1 or 2 reports reflecting one opinion or another
