There is just too much rubbish about ecigs to comment on... However, perhaps someone would like to point out that this statement on smokeless tobacco is equally ludicrous: "The concern was that people would perceive smokeless tobacco to be safer than cigarettes."
Well, yes; because it is many times safer:
- You can't get any kind of lung diseases from it
- Smoking causes four times as many oral cancers as the most harmful of all forms of chewing tobacco
So if you can find the numbers for sufferers of lung diseases caused by smoking as a percentage of the smoking population, and do the maths, you might be able to work out exactly how much safer chewing tobacco is than smoking. It's a lot, anyway. Purely as an estimate, use of chewing tobacco seems about ten times safer than smoking - maybe more.
If you then want to go to 'smokeless tobacco', you would need to include Swedish Snus. The health risks of Snus use are virtually zero: the health outcomes of smokers who totally quit, and those who switch to Snus, are statistically the same; Snus does not elevate risk for any disease. Sweden has the lowest smoking-related death rate in the developed world by a wide margin, as a result.
Chew on that.
