Much like fighting icons The Diaz brothers and Anthony "Rumble" Johnson, "Iron" Mike Tyson has entered the world of legal marijuana, and he's doing it in a big way. The boxing legend has purchased a 40 acre ranch and started construction on a massive marijuana growing operation. Socialunderground.com has it: Former world champion boxer Mike Tyson and his business partners Robert Hickman and Jay Strommen started construction on the 40-acre ranch on Dec. 20 in California City. The news comes just as recreational marijuana use became legal in the state on Jan. 2. But it won’t just be a growing operation. The ranch will reportedly feature a plant supply store, an edibles factory, an extraction facility, an amphitheater and campgrounds. Additionally, research will be done on how best to use and apply the healing properties of marijuana. Tyson’s cannabis farm will focus on “high quality strains of THC.” Thoughts?
