>Also, it is in Big Tobacco's best interest to make vaping as difficult as possible. Think about it, all these cities with vape bans haven't banned cigarettes yet, right? Make it extremely difficult to vape and people will resort to smoking.

Maybe, but vaping has (had?) the reputation of being "safer" than cigarettes. I doubt there would be a 1:1 of potential vappers to smokers.

Anecdotally, I know people who started vaping without ever having touched cigarettes before.

The English (maybe rest of UK too I dunno) approach is a voluntary code of practice for shops that sell vapes and juices to check that people have been smokers before selling to them.

I think this is the right approach for the UK. I'm not sure it'll work in the US.

How does that work in practice? Honor system? Asking to see a receipt from a cigarette purchase?

[DanBC]

It's just an honour system.

[landcoctos]

That's my point. Banning flavoring probably won't lead to as many using cigarettes.

[kortilla]

But it will lead to more using cigarettes. If it’s any more than the 20:1 safety difference then it’s still a net loss.

I'm confident there are significant numbers of people (read: kids) who would have never taken up cigarettes but took up vaping as the cool new way to get cancer.

[DanBC]

What cancer causing ingredients are there in vape liquids?

[partialrecall]

Possibly nicotine.

>Tobacco use is considered the single most important man-made cause of cancer that can be avoided. The evidence that nicotine is involved in cancer development is reviewed and discussed in this paper. Both tobacco smoke and tobacco products for oral use contain a number of carcinogenic substances, such as polycyclic hydrocarbons and tobacco-specific N-nitrosamines (TSNA), which undoubtedly contribute to tobacco related cancer. Recent studies have shown that nicotine can affect several important steps in the development of cancer, and suggest that it may cause aggravation and recurrence of the disease. TSNA may be formed from nicotine in the body. The role of nicotine as the major addictive component of tobacco products may have distracted our attention from toxicological effects on cell growth, angiogenesis, and tumor malignancy. Effects on cancer disease are important aspects in the evaluation of possible long-term effects from sources of nicotine, such as e-cigarettes and products for nicotine replacement therapy, which both have a potential for life-long use.
