While study after study seems to confirm that the risks associated with tobacco are lessened or even absent with MJ it'll still tear up your lungs and if you already have a lung related issue or are an athlete etc.
Enter the vaporizer. I have made several batches using Rosemary (dry hopped about 20g.) but that's for flavor and aroma. Personally I like to keep the two (alcohol and cannabis) separate, and by the time you start to feel the effects of the THC in your beer, you've already ingested far too much to be enjoyable.
FWIW, PBW does an excellent job cleaning glassware. Just sayin'.
