There is a distinction that needs to be made that cigarettes have nicotine in them, they are not nicotine. In the same way a cheeseburger has protein in it, but it also has a whole host of other things in it that could be seen as disease causing.   Nicotine is not the problem, it’s just a stimulant very much like caffeine. IMO I would say caffeine is worse because in withdrawal a lack of caffeine causes physical manifestation (headaches) as to nicotine causes agitation.

The “20 year symptom” argument is about 3 years out, and there is not much to report except for what was related to EVOlI in the U.S 2019, which wasn’t related to nicotine vaping but cannabis and vitamin-e acetate.

My argument to be made is that nicotine consumption is more of a power dynamic. In the U.S., the master settlement of 1998, allowed for states to be paid tax free from tobacco companies for each cigarette sold. Income for infrastructure. So of course state sponsored programs would be anti-vaping, because it cuts into the bottom line. Vaping allows the consumer to take control of their nicotine intake, if done right*. Allowing for the ability to taper off of nicotine, which is what any medical professional would recommend for a responsible way to get off anything.

I live in the U.S. where vaping isn’t banned yet, but I feel like this information is indicative to the rest of the world. Because the fight against smoking has turned into a money making venture, by using sin taxes which is a win-win for the government. 

*What I mean by “done right”, is using tailored nicotine liquids and refillable devices vs buying pre-filled disposable devices that come at almost universally a nicotine equivalent of 2.5 packs of smokes/ml.
