Massachusetts legalized recreational cannabis in 2016. According to the state, the industry here has grossed nearly $6 billion from hundreds of dispensaries across the state. As part of WBUR's Field Guide to Boston, a series aimed at helping folks better connect with the region, and in honor of the unofficial cannabis holiday on 4/20, we want to offer a quick guide for those who are curious about cannabis in Massachusetts. So The Common team took a trip to Heritage Club in Charlestown, Boston's first recreational dispensary owned by a Black woman, Nike John. She walks us through her experience working in the cannabis industry as well as the dos and don'ts of buying weed responsibly. Greater Boston’s daily podcast where news and culture meet.
