Hartfield exhibited at THC Expo, a two-day trade show at the Los Angeles Convention Center that attracted an estimated 35,000 attendees in June. There was hydroponic gardening equipment and bong vendors and bikini-clad models wearing leis made of fake marijuana leaves.

Like just about everyone else connected to the cannabis trade, Hartfield has a letter from a doctor that entitles him to buy medical marijuana from a dispensary. But he sees no point in pretending he is treating anything more than his taste for smoking weed.

"It is a joke. It's a legal way for me to get what I used to get on the street," he said.

He recalls telling the doctor who provided the referral that he suffered from insomnia and anxiety, though neither was true. As he signed the paperwork, the doctor "congratulated me like I was getting my degree from Harvard."
