This popular, potent medical choice is an indica-dominant cross of Purple Kush and Cali OG Kush, both widely loved strains. The exact balance of sativa to indica in this strain isn't widely known, but it leans heavily in favor of the indica genes. Though Purple OG Kush is said to be extremely strong, available THC numbers don't entirely back that claim, as they top out at around 18%. That's powerful, to be sure, but not quite top shelf. CBD numbers, meanwhile, are well below 1%, marking this strain as a poor choice for treating seizures or other maladies that respond to that substance. But Purple OG Kush can be used effectively as treatment for chronic pain, lack of appetite, insomnia, depression, and stress. The high, mostly physical, is deeply relaxing, spacey, and sleepy, with a pleasing body buzz. A sweet aroma of berries and musk pairs well with the fruity, Kush-like flavor of this strain. Expect dry mouth and dry eyes; other adverse effects include headaches, dizziness, and paranoia. Purple OG Kush is popular throughout the American West, from New Mexico to British Columbia, and can be found at many medical marijuana dispensaries. It also appears on the black market.
