I agree with this. I used nicotine lozenges to wean myself off cigarettes and this was successful.

However, I did notice as a side effect that they helped me concentrate on complex tasks.

So, although I don't use them daily, I leave a pack lying around just to suck on in the same way I might use a cup of coffee to sharpen up in the morning.

I genuinely believe this does me no harm. I think the debates started to get heated when inhalation is involved.
