Sour Diesel packs a powerful punch. It has a strong, diesel-like aroma and a dreamy high. Also known as Sour D, the first inhalation will leave you enjoying a strong sense of euphoria, a big boost of energy and a rich sensation of relaxation. It stimulates the synapses of the brain, but the head high is more spacey than cerebral. If you’re in a group, you might feel chatty and social. If you’re alone, you might feel reflective and deeply introspective.
