An indica-dominant hybrid (90 percent Indica, 10 percent Sativa) Zombie OG is a cross of Blackberry and OG Kush. THC tests show a range of 18 to 26 percent THC and 0.3 percent CBD. This strain won a prize in the 2015 High Times NorCal Medical Cannabis Cup. While the CBD is low, the mostly Indica effects work well for medical patients and recreational consumers who want to zone out and become zombies - the relaxed kind of course, not the “gonna eat your brain” kind.
