THC values in this especially powerful strain can top 22%, while CBD numbers are much lower. That cannabinoid makes up about 0.49% of this strain, which means it probably shouldn’t be used to treat seizures without other, more effective medication. But it’s a highly versatile medical tool and can be used to treat both mental and physical disorders: anxiety, depression, PMS, GI distress, migraines and other headaches, muscle spasms, nausea, and pain. Rainbow is an indica-heavy hybrid with a sativa/indica balance of 20:80, the result of a cross between Blueberry and Dance Hall. The high, often quite strong, creates a happy case of the giggles, a tingly sensation, and a potent dose of euphoria. The aroma is sweet, as is the taste, with hints of flowers and honey. Rainbow gets its name from its multi-colored nugs, which are covered in a glossy layer of trichomes. It sells best on the legal medical markets in Arizona, California, Colorado, and Montana. It may also appear on the black market, but it isn’t very common in most places. This strain may cause dry mouth and dry eyes, while paranoia and dizziness are also reported.
