Our Sour Diesel Shatter is 90% pure, making it one of the purest forms of tetrahydrocannabinol available. It contains almost exclusively THC. The Sour Diesel Shatter is produced by Phyto Extractions, as a result. There’s no intoxicating effect after ingestion. With the addition of natural terpenes, which are also extracted from the cannabis plant. Sour Diesel Shatter by Phyto Extractions, sometimes called Sour D, is an invigorating sativa-dominant strain named after its pungent, diesel-like aroma. This fast-acting strain delivers energizing, dreamy cerebral effects that have pushed Sour Diesel to its legendary status. 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.
