Sour Diesel, also called Sour D, is an invigorating Sativa-dominant strain that was named after its pungent, diesel-like aroma. This fast-acting strain gives energizing, dreamy cerebral effects that have pushed Sour Diesel to its legendary status. Sour Diesel is a top choice among medical patients that make stress, pain, and depression fade away in long-lasting relief. This strain took root in the early ’90s, and it is believed to have descended from Chemdog 91 and Super Skunk.
