I can't believe how rude people are to someone seeking advice!! There are no stupid questions everyone learns by doing research and from experience. I just recently researched this theory and its absolutely true. Its called "decarboxylate" and this Guy explains the science behind it and instructions on how to do it. I now do this before I cook or smoke my bud, its amazing. Like he says you can use microwave or oven, good luck learning more about the microwave "side effects" lol
I hope this link works, if not, its actually a thread on this site under recipes for making cannaoil.
