Like a few posters above me, I have no problems with minors vaping. I have no problems with minors vaping IF they were smokers and if they are indeed using it as a smoking alternative, not to stave off the shakes until their next deathstick. I would much rather see a 13 year old with an e-cig instead of his old analogs. I myself am pretty young and know I'm lucky to have realized relatively early that smoking was already killing me. My heart goes out to those that dealt with all the terrible things smoking brings and does for decades of their lives.
I honestly commend any teenage smoker who can have the clarity of mind to know that smoking is not cool, it's completely destructive, etc. While smoking and vaping is something that, in a perfect world, should be enjoyed only by adults, the world isn't perfect and kids get their hands on cigarettes and think they're badas*es. They're lucky (we're all lucky) they have an alternative like e-cigs and that the industry and culture is only getting bigger. Kids also get their hands on alcohol, and some will drink all their lives. Some will become alcoholics, and as far as I know there's no such thing as e-alcohol. Or e-c*caine Or e-h*roin... you get my drift. There are no real long term options for these addictions that don't eventually end in complete abstinence from the substance. Young smokers and everyone on this forum, all forums, and all ex-smokers current-vapors are lucky we essentially have a (fun, nifty) harm reduction strategy that allows us to enjoy nicotine in a safer way. I know everyone on here is grateful for that, and a teenager who wants to quit will be grateful for it too.
The problem is, of course, with teenagers advertising on YouTube. But you shouldn't be angry at them for vaping. If there's any reason we should be frustrated it's because they're only jeopardizing the efforts of all of us to ensure e-cigs stay legal and available for years to come... years when they're old enough to legally use PVs. (Think about it... someone who quit smoking and decided to start vaping at 14 is going to be super knowledgeable by the time they reach the legal age and can make YouTube videos for the community!)
No one shoot me for this, but I must admit there are very few circumstances under which I think anyone, legal or not, should begin vaping if they have never smoked. We all believe vaping to be healthier than smoking, it probably is. We all believe vaping to be almost inconsequential to any aspect of our health (at least 0 nic juice), it probably is. Since the volume of work is still so small (but ever increasing), though, it's really hard for me personally to accept the concept of anyone without a previous smoking habit picking it up... because there's no arguing that the fact of the matter, in this case, is that there isn't anything as safe as nothing at all.
If vaping is, however, the lesser of two evils then it should be used to the fullest advantage. For many of us, it is the lesser evil to smoking. In my teenage years, smoking was the lesser evil to a whole slew of other substances. (Trading addiction for addiction? Maybe, probably. Was it better regardless? Yes.) Someone mentioned thinking a young YouTuber might have had some emotional problems. As someone who can sympathize with that as well, if vaping helps you calm down in a time of true emotional crisis... more power to you. Better than needing Xanax to control your anxiety (and I am someone who needs Xanax to control my anxiety). I just don't think, at this point, vaping should be advertised as something anyone should pick up without a really good reason... if only because we are still waiting for more information. Legal adults at least have the ability to educate themselves on how to safely consume alcohol without damaging their bodies; alcohol has existed and been studied for literally thousands of years. (Not that it will take thousands of years to more conclusively prove the health ramifications of e-cigs... hopefully you get what I mean) Opposed to smoking, there's almost no question vaping is leaps and bounds healthier. I just personally believe there needs to be more extensive work done before it's something to even recommend to a lay person as a thing to just start. Just my humble opinion.
Flagging and voting down teens' vaping videos is incendiary and aggressive. If some feel that it is necessary for you to do that, for whatever reason, I pass no judgement when I say please do. For all others, I believe you should message the kid about his/her vaping. Ask how they started, heard of it, etc. Without being condescending, maybe explain why having a video on YouTube is harmful to the community (whatever your feelings on that are). See if they will remove it. If not, by all means, we should then flag away. We're protecting our cause and our rights. But young vapers' stories, motives, and feelings are just as checkered, varied, and unique as vapers of a legal age.
