Green Crack is a sativa-dominant hybrid that was bred by inbreeding Skunk #1. Green Crack is usually sativa-dominant, but there’s also a less popular indica-heavy version of the strain. This highly addictive strain is massively potent, with top THC levels reaching 24%. It has a sativa/indica ratio of 65:35. The high is decidedly cerebral, with a big mood boost and a jolt of energy. This strain spurs creativity and helps patients get things done. It’s most effective in treating anxiety and depression, along with ADHD, PTSD, and migraines.
