You are correct in that its not deadly in it's own right, I should have written that tobacco should be banned and nicotine with it. However, I think it certainly is fair to consider attendant consequences of its modes of abuse in regulating it--while the drug itself is not lethal in normal patterns of abuse, it's patterns of abuse do lead to deaths. It's acute lethal dose can be as little as 500mg and it is considered a deadly posion; it's actually a good thing in that regard that nicotine is rarely used "directly," as it would be hard to develop poisoning from regular use. But with the liquid in vapes themselves, that is a concern, particularly if small children have access. In terms of chronic effects, the biggest concern is adolescents and effects on brain development--not deadly, but definitely a direct harm from the drug itself. It is not a carcinogen, but it may be a tumor promoter. And it can lead to death or severe harm to the fetus if used by a pregnant mother as it crosses the placenta readily (a case of chronic levels harmless to mother reaching acute toxicity levels against the tiny weight of the baby). Lastly, the harvesting of tobacco does lead to consequences for the workers such as GTS which can cause serious symptoms. And regarding the addictive affect itself, I do see your point with regard to caffeine, however, I think it is important to consider the relative magnitude of its effects. Caffeine can lead to dependence and withdrawal, but the frequency of these effects doesn't lead to a public health concern on the level of nicotine, which is one of the core factors for a CSA scheduling action.
