Jack White, also known as "Jack Widow" or "White Jack" to some members of the cannabis community, is an insanely potent cross of the world-famous Jack Herer X White Widow strains. This celebrity child is a sativa dominant hybrid (80% sativa/20% indica) strain that boasts a THC level ranging from 18-28% on average. Jack White has a predominantly sativa cerebral head high that leaves you with a high energy head buzz and a sense of focused motivation. When taken in small doses, Jack White is an ideal strain for day use, but when taken in large doses, the indica effects become apparent and leave you sedated and couch-locked. Due to these potent effects, Jack White is an ideal strain for treating conditions such as chronic stress, anxiety disorders, and insomnia.
