i amoked brown mushy weed before and it did nothing to me.. think about it man, if it's in a sealed bag not much can go wrong with it.. it's not milk lol 2 months dont even sound like it would do anything to a bud.. if i was in your spot i would take all the good looking bud thats not brown and roll a blunt out of it thats if you dont have alot like 2 - 3 grams would make a nice brown mushy blunt lol dont get mad at me if you get sick just telling you what i would do or anyone i know for that matter
