Of the ones who only vape, most of them will still smoke the occasional dart. They'll smoke them if they can't use their e-cigarette (e.g. out of fluid, left it at home), because they're still addicted to nicotine they'll take what they can get.
There's also the social aspect of smoking cigarettes. I don't know why, but standing in a circle puffing on e-cigarettes just isn't as social as smoking a real cigarette, so if everyone else is smoking cigarettes the vapers will usually have a smoke too.
Why shouldn't those quitting smoking be allowed fruit flavours? I can only think you want them to fail and end up keeping on smoking tobacco.
Now one might say 'who in their right mind would want to start a nicotine habit?' Well centuries of tobacco use to more recent times with people eating detergent pods, huffing glue etc should readily provide the answer. Also, the tobacco industry knows what they're doing and I suspect it's not about getting people off nicotine but rather changing the delivery mechanism. (You do know big tobacco is big into vaping, right?)
I would be comfortable with discouraging kids as far as possible, requiring ID and so on. For some of the adult ex smokers I know, including myself, I doubt they'd have quit without vaping with some of the sillier sounding flavours. Some of the quitters will be kids who regret starting smoking 5 years previously. I don't have good answers to balance the conflicting needs or to prevent it becoming a growth sector far beyond smokers wanting out.
When I first tried vaping one of the few flavours I got was tobacco - which was awful, and never tried again. It took some months to step down the strengths to zero, and kept on vaping a while at 0 nicotine. That was 7 or 8 years ago, and no vaping or tobacco since.
Regulation in the US and UK is very different for vaping, but here big tobacco seems to be badly failing at vaping. Every shop that sells cigarettes now has a selection of the tobacco company's cartridge style "pretend cigarettes" vaping at five or ten times the cost of the simple juice bottles. I've only ever seen one person using one. Most towns have gained a juice stall selling cheap flavours.
I mean, it we remove all the bad part of being addicted to nicotine, why is it still bad to be addicted to nicotine?
It's like the experiment of a room with monkeys, ladder, banana and water hose.
By the way, there's nothing preventing one to use nicotine-free fruity vaping liquid.
I personally chose the fruit flavors when I was quitting cigarettes so I could distance myself from the flavor of tobacco, and it worked well for me. I cannot even finish a real cigarette now without feeling nauseated (even though I always seem to try after a few beers). I'm thankful for those fruity flavors every day.
If the quitting tool is less appealing, then it makes people more reluctant to quit. That's just simple logic.
I don't get why this isn't obvious.
> and start being addicted to nicotine as well?
Then they'll be addicted to nicotine. And?
You're dropping that like it's some sort of trump card, but the reality this is about harm reduction, and trying to find a policy that will lead to optimal outcomes. If you can get X smokers to switch to vaping while Y non-smokers also start vaping, is that good? Depends on the harm of smoking, the harm of vaping, and the size of X relative to Y. Just yelling that Y is non-zero number without all the other information we need is just pointless noise.
If "...and then they'll be addicted!" was a compelling argument, we'd be banning Starbucks.
If group X is larger and/or the harm avoided from their switching to less harmful behaviours is more serious, then a simple utilitarian calculation says yes, it is more valuable.
What data I've seen is still tentative, but suggestive that this is the case.
Do you have data to show the opposite?
However, in most cases e-cigarettes deliver only nicotine, while tobacco also also contains harmala alkaloid monoamine oxidase inhibitors. In animal studies[0][1] these have a synergistic effect in producing addiction when combined with nicotine, and anecdotally many humans report whole tobacco alkaloids having a subjectively different effect than pure nicotine.
