Galactic Jack is Jack Herer crossed with Space Queen to create this 70 % sativa-dominant hybrid. 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 approximately 18-26% in some tests. That makes this an incredibly potent choice for medication and recreation alike. CBD levels, meanwhile, are very low, less than 1%. Adverse effects are likely to include dry mouth and dry eyes, along with possible paranoia.
