Wow, strap on your massive judgey pants of judgedom..
I love vaping, I quit a 20 a day cig habit I'd had for over 20 years using a vape - not because I wanted to quit smoking, I loved smoking, but because I was likely to die of it quite quickly (smoking when you have heart failure is a bad plan indeed).
My GP is super happy I vape, my cardiologist thinks its fucking fabulous and told me he has many patients who have swapped cigs for a vape and are infinitely healthier because of it.
I plowed my way through the PHE report on vaping (thats the gummint for you, not just vapers) that basically says if its harming anyone, its just the vaper themselves, and it poses NO risk to those inhaling secondary vapour at all, it does not leave residue on the walls and surfaces inside buildings either.
I try not to vape in places that are not appropriate -I would not vape in a waiting room or in a hospital, or in a small public space like a bus or train, and I keep my sub-ohm MASSIVE CLOUDS vaping for at home only, really because it produces such huge clouds I can't see where I am going..
But the normal vape that produces a small amount of 'cloud', yeah, I'll vape that wherever and whenever I can - if you don't like it, tough titties really. I don't like smelling the stinking BO or the harsh perfumes or after shaves people douse themselves with - the other morning i was actually woken up by someone standing outside my house wearing perfume that smelt like a cross between cat piss and sherry... now that I am a non-smoker I can smell all this horrible shit, but I accept that smelling stuff I don't like is part of life!
Vapers DO tend to vape more constantly than they would smoke - because vaping produces a smaller amount of nicotine, with no clear cut 'end point', whereas smoking a ciggy gives you a big hit.. and then the cig is finished so thats your 'end point'.. having another will likely make you feel a bit sick and most people won't because they are on a time limit, they have gone out into the freezing cold to have that cig, because cigs are really expensive... whereas most of this doesn't apply to vaping.
But feel free to think I am a twat - I couldn't give a shit.
