Black Jack is a hybrid bred from Black Domina and Jack Herer. Reviews most often mention feeling energetic, uplifted and focused.
Across 52 public lab tests of Black Jack flower between 2021 and 2022, the median result was 20.3% total THC, with half of all samples falling between 18.5% and 22.1%. CBD is typically negligible (under 0.5%). That is in line with most flower on Canadian shelves. Potency varies by grower and batch, so always check the label.
In lab tests its dominant terpene is terpinolene, followed by caryophyllene and humulene. Terpinolene is known for fresh, herbal brightness with hints of pine and flowers, while caryophyllene adds black pepper and warm spice. Total terpene content measured a median of 1.8%. On the palate, people pick out pine, pepper and tobacco.
Beyond feeling energetic, reviewers also mention feeling creative and talkative. Some consumers say they reach for it when dealing with stress, anxiety and depression. The side effects mentioned most are dry mouth, dizziness and dry eyes. These are personal reports, not medical advice.
Parents: Black Domina and Jack Herer. Black Jack is also a parent of Jackalope.
