As regular readers know from previous posts here, marijuana has a whole slew of positive medicinal potential . . . a recent study shows directions in pain relief as an aspirin type substitute with research going towards the creation of non-psychedelic strains or medical forumulae. See http://www.nature.com/nchembio/journal/vaop/ncurrent/abs/nchembio.552.html for the paper published in Nature.

All the best,
