Jack Herer

Jack Herer is a sativa-dominant hybrid medical cannabis strain developed by Sensi Seeds in the Netherlands during the mid-1990s. It is a genetic cross between a Haze hybrid, Northern Lights #5, and Shiva Skunk. The strain is pharmacologically active as an agonist at the cannabinoid receptor 1 (CB1) and cannabinoid receptor 2 (CB2), primarily mediated by its delta-9-tetrahydrocannabinol (THC) content, which typically ranges from 15% to 24%. It also contains low levels of cannabidiol (CBD) and a specific terpene profile consisting of terpinolene, caryophyllene, and pinene. Jack Herer is recognized for producing balanced cerebral and physical effects, often described as blissful and creative, and has been distributed as a medical-grade product through Dutch pharmacies. Clinical research has explored its use in various settings, including its potential to improve oxygenation in patients following heart surgery.
