Candy Jack is the super-potent end result of a crossbreed between the famed sativa Jack Herer and the sativa-dominant Conton Candy . This Cannabis Cup winner has THC levels that can hit 35% making it easily one of the strongest strains in the world. CBD content, on the other hand, is low, less than 1%. The sativa genes dominate in Candy Jack, as they do in its parent strains (the exact ratio of sativa to indica in Candy Jack is unknown). That means a strong, peppy, energetic cerebral high with creativity and a shot of euphoria. Expect sharp mental focus while using this medical strain. The aroma is earthy while the flavor is sweet with hints of citrus. The best applications for this medicine include anxiety, depression, asthma, spinal cord injury, migraines, and chronic pain, as well as headaches. Candy Jack is also effective at inducing hunger in patients with wasting disorders. The downside includes frequent dry mouth and occasional dry eyes, headaches, paranoia, and dizziness. Look for this sought-after strain on the West Coast and Nevada. Elsewhere it’s relatively scarce, though it can probably be found on the black market in some places.
