Jack Herer crossed with Space Queen to create this sativa-dominant hybrid (sativa/indica ratio of 70:30 or more). Those genes produce a heady, cerebral high with a strong mood boost and a powerful dose of energy. The sativa dominance makes Galactic Jack a great choice for alleviating low mood, anxiety, and stress, while the indica genes provide treatment for fatigue, chronic pain, and muscle stiffness. THC levels are high, exceeding 26% in some tests. That makes this an incredibly potent choice for medication and recreation alike. CBD levels, meanwhile, are very low, less than 1% – too low to recommend this strain as a treatment for seizures or other health conditions that respond to CBD. Galactic Jack has a sweet, lemony flavor with hints of grapefruit and other citrus, and it smells of sweet lemons. The nugs are large and frosted with white trichomes. Adverse effects are likely to include dry mouth and dry eyes, along with possible paranoia, but there are few specific reports
