One of my big concerns is if someone start vaping will this person become nicotine addict or something like that.![]()
Possibly. There's no actual way to know until it's too late. That is, if you mean vaping with nicotine. There are also nicotine free versions of most all liquids and, no, those are not addictive.
vaping nicotine is best left to people already addicted by way of tobacco use. Like myself. I smoked for years. I am addicted to nicotine and have failed quitting each and every time. I always went back. Vaping lets me get the nicotine without the cancer causing chemicals in tobacco smoke (there are 50 or more!). But, see, I already was addicted to nicotine.
But there's no way to tell ahead of time. Some people can "smoke socially" even and don't seem addicted. Others quit fairly easily (in relative terms). Addiction is not a simple subject. Nicotine, itself, may not even be all that addictive. Other elements and additives in tobacco products likely boost addiction (we know the tobacco companies got caught researching and using ways to make their products more addictive).
If you do not use tobacco now, vaping nicotine is a gamble. You might not become addicted. Or you will. And you'd only know for sure by realizing you're addicted. That is, too late to not do it.
Zero nicotine liquids, though, have nothing addictive in them. The nicotine is the addictive part. Anybody who is not a tobacco user who wants to try vaping should ONLY try zero nicotine vapes. Why risk an addiction?
