But nicotine is not harmful...is it??
If you were a smoker and now vape nicotine was the least of your worries. The other contents of the analog, all 4000 known and unknown chemicals that are known to have certain effects and others not well studied yet, as well as 60 'known' carcinogens and tar that your rid of make nicotine look like fruit juice.
But nicotine does have its down side. It is known to cause high blood pressure especially if one has a propensity to elevated BP issues. It also increase your stroke risk. Relative to everything in an analog nicotine is tame, and since vapors were already inhaling nicotine its not like they were not exposed already.
No nicotine is not harmless and is not the same as water as some preach here even if its delivered in a water vapor but it does have health risks all by itself.
Nicotine is a poison. Its used as an insecticide (granted the bugs get a less pure form but its mean to kill them not protect them from particulate matter in the mic). It does not take much to kill a small child or a pet and we are warmed to not swallow it if on lips, in mouth on hands etc for good reason, it is toxic and can be harmful. Its also very addictive.
Its not a carcinogen and it does not do many of the other 'bad' heath things that the rest of an analog did so for the analog smoker to get rid of all that - even while keeping the nicotine - well for the smoker that a big change that seems to almost make nicotine sound 'harmless'
Nicotine has very real risks to the non smoker if they start using it - which is a good reason in my opinion not to be introducing a non smoker to vaping expecting them to take it up. And while, for the smoker, what tiny other things might be in e-juice and the effect of all the things that make up certain ingredients (like what type of flavors and what's in them). Again, a world apart form the dangers of analog consumption for the analog smoker but there could be some unknown risks with vaping we don't know yet. To me, even if they find out some solvents used in leaching natural flavors nag out and stay with the e-juice, its still only one more thing added to a very few instead of the huge number of things in analogs.
