Dispensaries are hit or miss. I know I grow better herb than any dispensary I've ever tried, but I've had some really good flower from a few dispensaries before, for sure. As far as rosin goes, you gotta make sure it's live rosin and not live resin, as some dispensaries will often mislabel on their menus and use these interchangeably. Rosin is the only true, natural extraction product as far as I know (besides the traditional hash, cream, and charras). Uses heat and pressure, only, as opposed to freezing and solvents, like the resin and all the other budders, sugars, badders, what have you. It is a clean high, and very potent and tasty, however, I still don't think it captures the full profile as much as flower. All the different cultivars of rosin I've tried, while all being various strengths and flavors, seem to have all pretty similar highs to me. I've rarely seen any of them test with much CBD, even from Indica strains that I know should have more CBD in the flower, which I find peculiar. They also destroy my tolerance, so I prefer to rock the ganj and make a small amount of edibles and bubble hash for those days I just want to feel it. The "live" just indicates that it's taken from the fresh plant without any processing. I have a portable, electronic dab device that works pretty well with the concentrates and is the only way I really like to consume them.
