PUEBLO WEST, Colo. — It’s 9 a.m. on a weekday, and I’m at the Marisol Therapeutics pot shop. This is serious business. Security is tight. ID checks are frequent. Merchandise is strictly regulated, labeled, wrapped and controlled. The store is clean, bright and safe. The staffers are courteous and professional. Customers of all ages are here.

There’s a middle-aged woman at the counter nearby who could be your school librarian. On the opposite end of the dispensary, a slender young soldier in a wheelchair with close-cropped hair, dressed in his fatigues, consults with a clerk. There’s a gregarious cowboy and an inquisitive pair of baby boomers looking at edibles. A dude in a hoodie walks in with his backpack.
