To me, vaping products were not a smoking cessation tool. They were to be an occasional substitute to actual smoking. I never had the intention to quit smoking when I started vaping. I just quit instantly and naturally because I enjoyed vaping a lot more than I ever enjoyed smoking.
For me at least smoking cessation was not the purpose, it happened as a consequence of having something I prefered to smoking.
Vaping is not meant to get rid of the nicotine addiction. However, people can use it for that purpose by gradually reducing the amount of nicotine in their liquids. It is not meant as a smoking cessation aid, although people may get into vaping to help them quitting smoking.
For me vaping products are a consumer product that allows people to experience something similar to smoking with far lower risk to their health. For some people it will not be that satisfying and they will give it up. Others will use vaping only occasionally instead of smoking and thus will only reduce their tobacco consumption (there is still harm reduction there). Others will vape only and totally quit smoking (much more harm reduction). The idea is not to quit smoking but to reduce the harm caused by smoking.
What defines a medicine is not just the substance or the method of administration, nor just its effects on the human body, but the intention with which it is used, that is to cure something or to alleviate a symptom. Using something because it may provide health benefits is not a medicinal use. For instance, eating fiber may be good good for your digestive functions, it does not make a bran muffin a medicine. Every time I vape instead of smoke I get the health benefits of not inhaling smoke to get my nicotine but it does not make vaping a medicine.
The thing that bothers me about tobacco companies entering the vaping industry in a big way, (and I feel the same about pharmaceutical companies for that matter), is that they have deep pockets and can easily manipulate governments in regulating vaping in a way that favors their business approach to the detriment of the customers. Those large corporations favor costly certification processes that are lenghty and expensive and will kill the small businesses of the vaping industry, killing innovation.
BT wants e-cigs to be treated as tobacco products and taxed as such, killing the economic benefits of vaping and slowing the development of the vaping industry, allowing BT to catch up by acquiring larger pieces of that industry. Offering a variety of products is costly, so BT wants also to limit vaping products to cig-alike with pre-filled cartridges, making sure that nobody else can sell liquids or make their own. basically, BT wants a uniform mass produced e-cig, so that small companies cannot compete because they will not have the economy of scale coming from mass production.
That would also suit Big Pharma, as those heavily taxed cig-alike would be much less attractive to consumers and would not compete as effectively againt the gums and the patches. On top of that, the slower growth of vaping would keep more smokers on cigarettes, allowing Big pharma to continue to sell more drugs for the treatment of health problems caused by smoking.
For Big pharma however, the greatest gain is to be had if vaping products are regulated as smoking cessation aids. That would essentially leave them as the only players
