No one seems to know exactly what cross led to this potent indica. But THC levels are very high, making this an appealing strain for many patients. At its strongest, Mercury OG can be as much as 23% THC. CBD contents, meanwhile, are quite low, about 1.6%, though that’s higher than average. This strain has a pungent buttery aroma and a sweet flavor. It causes a profoundly euphoric body high with a boost of goofy, giggly energy. Patients who use Mercury OH frequently find themselves talking and laughing more than usual. It also creates a tingly sensation and stimulates appetite. That makes it a great choice for patients who need to gain weight, as well as anxiety, chronic pain, and insomnia. This strain is best saved for late at night, as it can induce powerful couch-lock. There are few reported side effects, though bloodshot eyes are likely and paranoia is possible. Mercury OG is sold on the legal medical markets in California and British Columbia, but it’s not very common elsewhere. It may appear on the black market from time to time, but it’s definitely not a regular.
