This potent favorite, available on and off the legal market, is a phenotype of OG Kush, a sativa-dominant hybrid with THC levels that can top 24%. Pure Kush definitely carries some of it’s parents best genes. It’s an indica-dominant strain (15:85 sativa/indica ratio), and though its potency varies, it’s nearly as strong as its parent: Some tests show THC levels over 25%, making Pure Kush one of the world’s strongest strains. CBD levels, on the other hand, are much too low to recommend Pure Kush for treatment of epilepsy. Rather, its best medical use is as treatment for anxiety, depression, chronic physical pain, and insomnia. The body high is strong, fast, and profoundly relaxing, with a calming physical buzz and euphoric, creative cerebral effects. Adverse effects are limited, though dry mouth is relatively common; red eyes, paranoia, dizziness, and headaches are also possible but not typical. Pure Kush is popular on legal medical and recreational markets in both the United States and Canada. It sells best in Oregon, California, Montana, Montana, Arizona, Ontario, and British Columbia. It’s also a favorite on the black market in many places.
