suhweet! I'm glad to know they are finally figuring out whats going on, and that you have a little more peace of mind.
As for snuffs and nicotine, I;d also suggest
Toques Quit! snuff and
McChrystal's S'Nuff (Aka Smokers Blend) for those with high nicotine. I haven't tried either of them, but I'm sure they are worth a shot. Stay healthy, Brother!
