„In contrast to the well-known addictive potential linked to the chronic inhalation of nicotine, none of the trials could show a nicotine dependency after the withdrawal of transcutaneous nicotine application at the end of the investigations“
As a former smoker, who used patches and gum and such to quit, this doesn't seem surprising. The nicotine patch is far less satisfying than cigarettes. Cigarettes come on strong, immediately, and that feeling is amazing.
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.
