A seminar taking place on the University of British Columbia campus this weekend will train wannabe medical marijuana entrepreneurs. Greenline Academy, the organizer, told The Province that its $330 seminar is sold out. The course will cover everything from the legalities of medical marijuana to growing techniques. The classes have already been taken by more than 1,300 people in cities from Winnipeg to Victoria since Greenline opened in 2011. A permanent school is planned for Kelowna, B.C. Health Canada has issued more than 12,000 licenses to grow medical marijuana.
