Well i used cheddar cheese, the kind that comes in a block kinda, by Kraft, and you slice it off, i used 2 pieces that were about .5 CM thick (about as thick as 2 nickels stacked together), and just fit it to the cracker, and i put the weed [b]between[/b] the 2 slices of cheese ( i think this helped prevent the smell!!) and cooked it for a minute and a half ( to ensure THC bonding) and voila!!
I suggest trying it, and if you do, enjoy!
Just, one thing, i wouldnt recomend more than a gram or two in there, because i used like .5 or 3/4 of a gram and i had a panic attack. lol but that could just be me, i'm a real lightweight.
