It is a matter of why pick up your first beer, cigarette, jello shot, beer ...., why did you get your first tattoo? Someone introduced someone you knew to it who showed you and introduced you to it. This like all others before it has become a cultural phenomenon there are those that use it to quit the cultural phenomenon called Newport, Marlboro, Camel, Kool, etc. Now huge plumes of aromatically wonderful vapor is the taking the world by storm and if people that never smoked are leaning towards it and they are vaping as a hobby versus an alternate to tobacco products and they are getting non nicotine juices what's the harm? I know 4 guys that went to vaping to get away from chewing tobacco and you know what it worked now they vape solely for flavor. I know a couple people that took up vaping just for the tech side of things they enjoy trying to build the ultimate cloud machine builds and others that are doing it as a form of meditation aid hey they aren't using nicotine it is for the experience or the fun factor and it isn't causing them any harm. So if they vape safe and don't exceed battery and device capacities the only risk they really have is maybe they have an allergic reaction to a certain flavoring extract or a PG/VG intolerance but it isn't like they just shot ...... or smoked a hit of .... or dropped an extasy pill. If it creates a culture of friends and healthy fun I say the world can use more of it. It isn'tlike someone who vapes is ever going to start smoking if they never smoked a day in their life because the taste of it alone would be so repulsive and the nicotine buzz would be so overpowering that it would make them sick plus where are you going to find a cig that tastes like captain crunch-berries or strawberry kiwi jolly rancher the reverse appeal of vaping to cigs IMHO is slim to none it is hardly the same experience I smoked for 30 plus years and the only thing that vaping has in common is the act of inhaling, outside that they are 2 entirely different experiences flavor, texture, and health benefit wise I can't ever imagine someone saying they needed to quit vaping so they were going to take up smoking.
