Like its namesake, boxing champion Mike Tyson, Tyson is a strain with the sheer power to knock you out where you stand. Although Mike Tyson himself has taken up cannabis farming, having opened up a weed-themed resort in the Mojave Desert, this pure indica is actually the creation of Canna Clinic. And while the strain’s genetics have been kept proprietary, there’s nothing secret about Tyson’s potency. Its THC content has been measured at between 12% and 21%.
