if there is weed inside the blunts then how could you get addicted to nicotine? Ive smoked a number of blunts in my time, and i have never had the urge to smoke a cigg. Sure i guess you could say that something could rub off on the paper and then you smoke it, buts its not that big of an issue to worry about getting addicted. Ive ever smoked numerous ciggs in a night for the hell of it one night when i was fucked on a few things, and i didnt feel the urge the day after. I dont think you will have a problem. Light it up and have a good time
I would think that the all powerful THC will overpower any of that pussy Nicotine that may be in the wrapper...
But seriously, there's probably not very much Nicotine in the cigar wrapper...
Also - you will need to smoke more than one "blunt" in order to get addicted. Unless you are smoking them with cigarette like regularity, you're unlikely to get physically addicted to nicoteine.
