A strain specific pre roll by Tyson 2.0. Sour Diesel or, Sour D, is an energetic, Sativa-Dominant strain noted for its trademark pungent, sour, citrus and diesel smell and its quick-acting, dream-like effects which are long-lasting and prone to expose the consumer's mind to new ways of thinking. Often encouraging a walk in the woods or on the beach, this head-centered, mood-elevating strain is not known as a knockout.
