Well do you go to /r/coffee and tell them that? There's nothing inherently wrong with addiction as long as it doesn't have a huge negative impact. If someone can't quit smoking cold turkey, this is the way to go. I'd go as far as to say that the vast majority of smokers have tried to quit multiple times and failed. Shit's hard. Why anyone would be against something that reduces the harm to themselves and others generated by smoking is beyond me.
