Few strains compare to Green Crack’s sharp energy and focus as it induces an invigorating mental buzz that keeps you going throughout the day. Dont let the name fool you-this is pure cannabis. Its lineage represents a cross between Skunk#1 and Sweet Leaf Indica.. The high is decidedly cerebral, with a big mood boost and a jolt of energy. This strain spurs creativity and it’s most effective in treating anxiety and depression, along with ADHD, PTSD, and migraines due to the abundance of terpenes like Myrcene, Linalool, Camphene, Valencene, and Phellandrene.
