It looks like we brainwashed ourselves into thinking nicotine was the reason for quitting cigarette smoking in the first place.
In reality it was smoking of plant materials itself... the burning, the tar, the xylene, the acetone, the cyanide..
The word Nicotine became synonymous with smoking, and we have fought to separate it from the terror.
We separated and have liberated it into just another compound that has its good uses and bad uses.
So, if your inclined to think, as most people like to do, just do things in moderation. Same as all we consume in today's world.
Consuming too much of a good thing is good or not, that is the question....
