Make Cannabutter, its way less likely to be shite.
Just get a pot,put about an inch of water in it, put it on the lowest heat setting on your stove (dont use a gas stove, too hot). Dissolve a stick of butter in it and add your herb material. I use fresh frozen trim. Leave it for 2-3 hours simmering but NOT boiling, stirring occasionally. Then pour it into a Tupperware container and leave to harden in the fridge. Just scoop the butter off the top of the water and your ready to rock. Dont eat it by itself tho, its sick tasting.
I used about 14g's of trim last time, made 8 cookies, and 1 is enough to feel like you got a concussion or something! Simples.
