Most everyone we know in the medical cannabis world hates the name of this strain—could “crack” be any less medical?—but no one doubts its potency. Simply put, Green Crack is one of the most intense medical cannabis strains of which we know. It’s a special Super Skunk #1 phenotype crossed with, in this case, Sweet Leaf indica. Green Crack has a reputation for producing intense, cerebral head highs, and this example from Natures Resource Center in Tacoma is true to the norm. It tests at 19 percent THC and 1.1 percent CBD (the latter quite high for a sativa), according to the collective, and its effects are both highly activating and thought-inducing. True to its Skunk lineage, its big buds smell sweet and skunky. This strain is excellent for pain relief (you won’t even feel your body) and anxiety along with muscle spasms.
