Jack Herer is a popular sativa-dominant strain that was named after the well-known cannabis activist and author. Its genetics come from Haze, Northern Lights #5, and Shiva Skunk crossbreeds which give it its distinct effects such as cerebral elevation and resin production. Jack Herer has several variations with unique features but all tend to leave users feeling blissful, clear-headed, creative or energetic according to Leafly reviewers. It originated in the Netherlands where it became recognized as medical-grade marijuana by Dutch pharmacies due to its potency and quality leading up until today where consumers still enjoy this spicy pine-scented strain's numerous awards for being one of their favorites on the market!
