Green Crack: Green Crack’s effects are truly sativa-inspired, with a few hits of this strain being likened to downing a cup of coffee. Green Crack is said to be a cross between a 1989 Super Sativa Seed Club, a Skunk #1, and an Afghani landrace. The strain was reportedly named Cush by its original breeder, Cecil C, then renamed Green Crack by Snoop Dogg ro refer to what the rapper and cannabis activist perceived as potent, sativa-like effects.
