Black Jack has a high that strikes the user quickly, leading to a sense of heaviness in the head. As it progresses, the effects are generally uplifting, anxiety-reducing and depression-relieving. Users report a lasting sense of focus and motivation, although this energy can veer into jitters and paranoia depending on dosage and individual tolerance. Although there is a mild body high, this strain, like Jack Herer, strikes a very good balance between cerebral and physical effects. Sweet Seeds’ Black Jack is appropriate for daytime use for users looking to complement daily activities or possibly exercise routines.
