Sour Diesel, sometimes abbreviated as Sour D, is an extremely popular strain, distinguished by the fuel-like chemical smell of its flowers. It has a mostly sativa head high with some subtle physical indica relaxation, making it popular among recreational and medical users alike. This is a potent strain, with a THC content that had been measured at between 20% and 25%.
Because the underground cannabis market of the 1980s and 90s operated without any kind of lasting documentation, the exact origins of Sour Diesel are not known. Although a definitive agreement on its original genetic makeup doesn’t exist, Sour Diesel’s popularity has made it the subject of much speculation. Some believe that true Sour Diesel was derived as a distinct phenotype of an original strain simply named Diesel. Others say that it was a phenotype of Chemdawg that leaned more sativa than indica. Still, others claim that it was a cross of Chemdawg and Northern Lights, or perhaps Chemdawg, Northern Lights and Skunk #1.
The high from Sour Diesel comes on users quickly in the form of a warm and pleasant head rush. An uplift in mood may be noticeable as well. Although Sour Diesel stimulates synaptic activity in the brain, the character of this head high is more spacey than intensely cerebral. Users may feel chatty if surrounded by others or somewhat introspective if enjoying the strain alone. For many, this soaring high is partially anchored by a slight feeling of physical relaxation. That said, a body stone that leads to full-on couchlock is rare. The sense of euphoria that comes with this variety may be helpful in treating some symptoms of mild stress, anxiety, or depression. Its tendency to lead to associative thinking may provoke a bit of creative inspiration.
