Former 49ers quarterback Joe Montana is part of a 75-million dollar investment in the legal marijuana industry. The Hall of Famer said yesterday his venture capital firm was investing in an industry he believes “can provide relief to many people” and impact “opioid use or addiction.” Montana is investing in San Jose-based Caliva, which currently owns a farm, retail store, distribution center and delivery service. The company didn’t disclose Montana’s portion of the investment.
