A dispensary has yet to open in the Island City, but commerce in cannabis products was in full swing Saturday, Aug. 24, when Alameda Natural Grocery hosted an event promoting supplements containing CBD (cannabidiol). This non-psychoactive component of cannabis has some proven health benefits. Representatives of 16 manufacturers answered questions and offered samples of salves, tinctures, edibles and drinks — all are available at the Alameda Marketplace at Park Street and Buena Vista Avenue.
