I started vaping 8 years ago! Since then, I became pretty much expert on the topic.
Ofc, it's mainly and primarily - stop smoking tool. Im strongly against youngsters vaping. Also against those who never smoked to start vaping. Thats why I dislike "vape models" (girls that promote products simply based on their physical look) as well as vape trickers (those that make tricks with clouds) - all that brings younsters into vaping (those who never smoked) - much more than flavor called 'Chocolate' .... (im refering to FDA flavor bans)
As fo health - Its a fact that regular cigarette has 4000 chemicals, many cancerous. Ecig has 4. And in letters - f o u r - propylene glycol , glycerin, flavorings and eventually - nicotine. Even nicotine can be removed completely! So its - 3.
3 vs 4000!
I dont trust people / never trust anyone (including me) - trust doctors. There were long term studies done! You can easily Google it.
Tobacco industry is ofc against vaping, protecting their profits, lobbying... All the "bad press" comes from them, one way or another.
In a decade or two, Im sure there will be more vapers than smokers in the World. Its already big industry. When i started, things were small, you learned via (small) online forums. Devices were primitive.
In 2014/15 things exploded and vaping gained momentum.
