This three way cross is a descendant of the legendary Master Kush, the even more legendary Hindu Kush, and Montel’s Pride. It’s indica-dominant, but the exact ratio of sativa to indica isn’t clear. THC levels hover between 17% and 22%, making Rainbow Kush a very potent medical selection for the treatment of anxiety, chronic pain, stress, depression, fatigue, nausea, and muscle spasms. The indica genes propel the high in this strain, which comes with a deeply calming body buzz balanced by happy, focused cerebral effects. CBD concentrations are roughly one half of 1 percent, which is too low to suggest this as good treatment for conditions that respond to CBD, such as childhood epilepsy. The negatives associated with this strain include dry mouth, dry eyes, dizziness, paranoia, and limited headaches. Also known simply as Rainbow, Rainbow Kush can be found at multiple medical marijuana shops in the Pacific Northwest, Montana, Arizona, and Colorado.
