Remember, nicotine!=tobacco
Nicotine is a fascinating topic. I do wonder if, in the context of massive obesity prevalent in America, society would be better off with nicotine addiction.
Could it be analogous to how caffeine addiction in our history kick started the knowledge work revolution?
Patches are a slow release and the effect comes on very gradually.
There's no cue/craving/response/reward feedback with patches(Tiny Habits helped me quit too if anyones trying).
If I get irritated and have a cigarette, there is immediate relief and satisfaction. I can't immediately put on a patch and get that. Probably takes thirty minutes to really come on.
Not saying there is no addictive potential, but they are off by an order of magnitude or two.
So are a lot of medications, I'm not sure what point you're trying to make. Can you elaborate on why you thought it was important to comment?
