Apple Jack is a sativa-dominant hybrid created by crossing the famed Jack Herer sativa with White Widow, an equally notorious hybrid. Apple Jack has a sweet fruity flavor to go with its name, as well as a sweet but pungent earthy aroma. This strain isn’t widely available, so there’s no real data on its negative effects. For that matter, it’s hard to say where this unique strain can be found, though it’s probably sold on Western markets.
