no. not as far as i know.

i have made brownies when i totally burned the weed. the thing is... olive oil is very stable. you cant get it too hot man! its not going to evaporate.

high heat means dramatic thc transfer. and oh shucks.... we just happen to have a fatty oil in close proximity when the thc is being released by the heat.

if you burn the weed black in the pan..... the brownies will be far too strong, even in small amounts.

try it. i promise you wont be dissapointed. use high heat. then come back and tell us what happened.
