High in THC, AK-47 has won multiple Cannabis Cups. Originating in 1992 from Serious Seeds, the resin-heavy, bright-white colored skunky hybrid is sativa-dominate and effective in relieving anxiety and stress. Patients suffering from bipolar disorder and depression find AK-47 a useful strain to relax and regulate moods, as well as stimulate the appetite and alleviate nausea and vomiting.
