Frankly, I don't think addiction to nicotine patches is a problem especially if you only use them a couple of times a week. Think about it. The typical addicted smoker goes through a pack or more a day. With a nicotine patch, the dose is much lower and you only one per day (at night). The other thing about smoking addiction is the oral gratification of putting something in your mouth (like sucking your thumb) and the gratification caused by smoking being a social activity. This means that a large part of smoking addiction is addiction to a behavioral habit.

At any rate, I think a nicotine patch is okay two or three times a week.
