Also known simply as Diablo OG, is named after the Spanish word for “the devil.” It isn’t exactly that, but it’s definitely an effective medical strain. THC concentration can reach 20%, while CBD levels are less than 1%, making this a less-than-ideal choice for treating seizures or other conditions that respond to this cannabinoid. El Diablo OG has a sativa-to-indica ratio of 60:40, so the high is largely cerebral, with clear-headed effects, a strong dose of euphoria, and a moderate body buzz. Medically speaking, this strain is helpful with chronic pain, anxiety, insomnia, and migraine headaches. Dry mouth, as usual, is the most common side effect. Dry eyes, dizziness, and paranoia are also possible, though less likely. El Diablo descends from OG Kush, one of the world’s best-known strains, Blueberry, Grapefruit, and an unknown African plant.
