What is Sour Diesel Cannabis Oil? Sour Diesel cannabis oil has got a distinct, pungent gassy stench that is coupled with an exciting burst of energy. Having Sativa lineage, it is correct to assume that Sour diesel will predominately affect the mind. Patients typically use Sour Diesel Cannabis Oil as their first source of medication to start the day; it’ll have you feeling awake and ready to go. Sour D affects your head almost exclusively; there’s absolutely no couch-lock or heavy body feeling. The way I think of Sour Diesel Cannabis Oil is similar to how a dog reacts when it sees a squirrel. Head perks up, instantly aware of your surroundings, and sort of tuned into your environment like you’ve never been before. It seems to work with the brain to create tons of ideas and energy.
