No man, it doesn't take that long at all. 15 minutes at 350F works for me, I just put about 3 of them wrapped in alluminum foil, and put them in my toaster oven. The peanut butter and the aluminum foil mask the smell as well, so you don't smell the pot unless you open up the crackers. They took about 1 1/2 hours to kick in for me, but I ate mine at night. If you eat them before school, you'll probably get pretty fucking stoned out of your mind around 2nd or 3rd period. I don't cook my weed that often, because I like how smoking gets you high alot quicker, but whenever I have an ounce, I'll usually cook about an 8th of it.
