GreenRock Cannabis is open for recreational use only.

Medical patients and recreational users have access to similar products, but vary when it comes to serving sizes, taxes, and allotment.

Recreational use edibles are limited to a dose of 5mg THC per serving and 100mg for the total package. Recreational users may purchase up to a total of an ounce of flower per day or the equivalence of an ounce in other products (5 grams of concentrates or 500mg of edibles.)

Medical patients may purchase edible products with much higher dosing and package sizes. Medical patients may also purchase and possess a 60 day supply, or up to 10 ounces, at a time.
