marinol... doubt it, its synthetic thc. Not sure if it would be te same for allergies. why not try the weed, like at least 2 other people have suggested. and no being allergic to trees and grass has nothing to do with being allergic to cannabis. Saying your allergic to pot because your allergic to grass and trees (what the fuck kind of trees even?) is just funny sounding. In fact, a lot of what youve been saying is kinda funny... no offence, but your TEMPO hurts? Oh, and try smokin out of a new sac, instead of "looking" at yours to say that practically invisible traces of chemicals arent there. Or just stop smoking, and dont worry about it.
