Silver Stem doesn't seem to be offering quite the variety of strains it did during its medical-only days as Cannamart, but that just means that instead of forty-plus options on the shelves, you're looking at approximately two dozen — still not too shabby. There's still a solid mix of heady top-shelf nugs, plus some lower-grade selections that aren't quite as crystal-laden; you'll also find edibles, vaporizers and refills, tinctures and more. Located at the corner of Quincy Avenue and Lowell Boulevard, it's in a strip mall that doesn't see a whole lot of action apart from pot-seekers pulling into and out of the parking lot all day long. A sparse waiting room includes a television for anyone who simply must catch the last few minutes of the game before heading into the dispensary proper, and the staff is friendly and happy to help novices and veterans alike with cannabis selections. The specials on shatter and other extracts are particularly noteworthy.
