Jack the Ripper is a sativa. You may also see it sold as JTR. Reviews most often mention feeling energetic, creative and uplifted.
Public lab results give a good picture of its strength: 5 flower samples tested in 2021 came in at a median of 15% total THC (the middle half ranged from 14.2% to 15.1%). That is on the milder side for modern flower. Potency varies by grower and batch, so always check the label.
Its reported terpene profile is led by terpinolene, with myrcene and pinene. Terpinolene is known for fresh, herbal brightness with hints of pine and flowers, while myrcene adds earthy, musky notes with a ripe-fruit edge. Consumers most often describe the flavour as lemon, citrus and spicy/herbal.
Beyond feeling energetic, reviewers also mention feeling talkative and focused. Some consumers say they reach for it when dealing with stress, anxiety and depression. The side effects mentioned most are paranoia, dry mouth and anxiety. These are personal reports, not medical advice.
Jack the Ripper is also a parent of Chernobyl, Pennywise, Pandora's Box, Mickey Kush, Jack Skellington and Nurse Jackie.
