RE:Medical Marijuana Patients in California
"Notes: 1. California has registered 84,111 card holders since the program began, but cards are only valid for one year; 6,490 cards were issued FY2014-2015. California's registry is voluntary, so the number of cardholders likely underestimates the number of users." There are definitely WAY more than 800,000 patients/customers/consumers in California, so I think your estimated annual $3.3k spend per user is way too high. It would be brought down a lot once you take this into consideration.
