No. You would burn the active chemicals, and you wouldn't get high if you did that.
THC dissolves in fat, so you make a double-boiler (you boil water and put a second pan in it), and melt the butter, and dump the drugs in it. The THC dissolves in to the butter, and then you use the butter to bake whatever you're making. Go easy on the heat, and if you start to smell it, you've ruined the batch.
