Venom OG was created by the cannabis breeder, Rare Dankness, and is a cross between Rare Dankness #1 and Poison OG, both of which have Chemdawg heritage. Emitting an earthy, skunk-like aroma and a flavor reminiscent of diesel, Venom OG is a potent strain, with THC levels ranging from 11% to 27%, according to the cannabis seed bank Amsterdam Seed Center.
