Veteran Bay Area investigative reporter John Geluardi released his first book, Cannabiz: The Explosive Rise of the Medical Marijuana Industry this October. A former staff writer for the SF Weekly, Geluardi saw so much momentum building behind medical pot, he researched and reported a 200-page non-fiction paperback. Geluardi talks about investing in pot, economies of scale, and new fissures in the field in this two-part Q&A edited for length and clarity.
