I'm also libertarian. I think that is why I have a hard time wrapping my head around it. I don't care what other people do or how they decide to live their lives as long as it doesn't interfere with others' rights. Plain and simple.
I'm glad to see that quite a few people here aren't the kind that want to dictate who can vape or not, but I read another thread earlier where people were actively trying to discourage a non-smoker from starting to vape. *sigh*
I feel much the same; I don't hurt anybody, and I don't want anybody hurting me -- including, perhaps *especially*, my own government! They're supposed to be on my side, not be my worst enemy! But in recent years, they've striven mightily to be the worst enemy of every American on the planet, and are well on their way to succeeding.
For a non-smoker who's NEVER smoked to want to vape, I kinda feel like, why? What's the point? Because it's "cool"? That was my juvenile reasoning for starting to smoke at the age of 13, and at the age of nearly-53, I see how stupid that was, and I guess I feel like it's just as stupid to start vaping for that reason. But last I checked, they hadn't yet made a LAW against stupidity; they'd have to lock up 3/4 the population if they did.

If someone over the age of 18 wants to vape, regardless of smoking history or lack thereof, regardless of the possible stupidity of their reasons, I don't think there's really a need to stop them; if they try to vape nicotine with no history of its use, they'll soon find out the stupidity of their action, and either stop the whole endeavor, or start vaping 0mg -- so I don't see a problem with it at all.
For a ex-smoker who's powerfully tempted to start smoking again, I would urge them strongly to try vaping instead. For a non-smoker who's never smoked but who has compelling medical reasons to self-medicate with nicotine, sure, why not? Apparently it's a stimulant on the same order as Ritalin, capable of coordinating chemical processes in the brain, and may even be a valuable drug in preventing various kinds of dementia.
Apparently BP discovered years ago that nicotine is not harmful, in low doses, or all those patches and gums would still be prescription-only; it's the very essence of venal hypocrisy for them to now to have qualms over the "safety" of nicotine use -- the only legitimate qualms they have is over their bottom line, and the fact that when they were offered e-cigarettes back in the early 60's, they took a pass -- the ship has sailed, and they're standing on the pier, watching it sail off with all the money that could have been theirs, if they'd decided to have a go with e-cigarettes themselves. I think we should enjoy a rousing chorus of "neener, neener!"
