I dropped in on a marijuana shop here that proudly boasted that it sells “31 flavors.” It also offered a loyalty program. For every 10 purchases of pot — supposedly for medical uses — you get one free packet.

“There are five of these shops within a three-block radius,” explained the proprietor, Edward J. Kim. He brimmed with pride at his inventory and sounded like any small businessman as he complained about onerous government regulation. Like, well, state and federal laws.
