Allen Wrench is highly sought-after for its medicinal qualities. This combination of Trainwreck and Sour Diesel is mostly sativa, meaning that patients feel active and euphoric after medicating. Despite the fact that this strain does not have intense "body effects" or any "couch-lock" sensations, Allen Wrench's CBD content coupled with its high THC percentage makes it an effective medication for eliminating pain throughout the body. It should also be noted that even though this strain is sativa dominant, it's high CBG levels do tend to make one's eyes feel "heavy" after medicating. It's above average THCV percentage is also useful for helping patients cope with headache pain. For those who have not built up a tolerance to THC, a lower THC alternative is recommended.
