should vaporizor be emptied after use?

Yes then add the stuff from the vape to brownie mix once u have a good amount. If you vape your pot you can take the "burnt" stuff out put it in a pipe and smoke it again. Same thing with the brownies theres still plenty of CBD and thc that the vape doesn't burn! Hope that helps
