The behemoths of Denver’s marijuana industry: Vail’s largest commercial developer. An owner of a car-detail shop. A former nonprofit event planner. A businessman who made a fortune in child car seats. A one-time Subway franchisee bankrupted by real estate losses. These marijuana business entrepreneurs — Peter Knobel, Joshua Ginsberg, Rhett Jordan, John Lord and John Fritzel — have emerged atop Denver’s pot industry just two years after the first recreational joint was sold. In all, they hold 134 marijuana business licenses in Denver — about 13 percent of the total. An analysis of marijuana license data in Denver, which accounts for about 44 percent of licenses statewide, reveals for the first time who is behind the pot industry and how the market ownership has evolved since January 2014. –Report by The Denver Post’s David Migoya and The Cannabist’s Ricardo Baca

Driving high: Legal limits have no scientific basis: Six states that allow marijuana use have legal tests to determine driving while impaired by the drug that have no scientific basis, according to a study by the nation’s largest automobile club that calls for scrapping those laws. The study commissioned by AAA’s safety foundation said it’s not possible to set a blood-test threshold for THC, the chemical in marijuana that makes people high, that can reliably determine impairment. Yet the laws in five of the six states automatically presume a driver guilty if that person tests higher than the limit, and not guilty if it’s lower. As a result, drivers who are unsafe may be going free while others may be wrongly convicted, the foundation said. –Report by The Associated Press’s Joan Lowy
