There have been many people that quit smoking cigarettes by vaping. Because of this I withhold judgment on vaping. I’m from the age where I grew up with a mostly constant vaporizer working in one of our many bedrooms. I’d rather be in a bingo hall with vapers than smokers.
I've been vaping since 2012. I quit cigs in 2013. I make my own coils and buy my own Japanese cotton for the wicks.
The problem a lot of people new to vaping is the premade coils and lousy e-juice. And yes, one can order the amount of nicotine in that juice. I've been at 3mg for years. The next step is zero.
So, in the 13 years of vaping I have had NO issues at all. None. Zero. All of that despite some of my friends/relatives saying it's going to kill me.
Heck, my own doctor said she would rather me vape than smoke. Of course, she said, "If you're not going to quit nicotine addiction, I'd rather you vape than smoke cigarettes."
Carcinogens/nicotine in cigs vs just nicotine in e-juice. Nicotine is addictive like caffeine. It's a stimulant like caffeine. Coffee good. Vape bad.
Like everything else in life, people need to do some deep research before babbling about crap they know nothing about.
