wait what?
:hmm:
first of all...what does that have to with comparing it to sugar and caffeine? If you are saying that nicotine addiction is not a top cancer-threat, then I simply have to say you are either trolling or hilariously ignorant.
second: sugar and caffeine are horrible for their own reasons:
nicotine is well on its way out, it seems, or at least at manageable population levels. The next big, and honestly real bug-a-boo is sugar. Diabetes is fucking crippling this country, and while that isn't so much an issue of cancer, it does not mean it isn't dangerous.
But well, you know, .....good luck wrestling that Krispy Kreme donought from Fatty McGee's hands. (no, seriously: those things are delicious)
