In compliance with state regulations, you can purchase up to one ounce of usable cannabis in a single sales transaction. This means you can either purchase one ounce (28.35 grams) of cannabis flower, four grams of cannabis concentrates or resin, four grams of vaporized formulations (oils), or 1000 mg of ingestible cannabis infused products (i.e., [quantity of ten] 100 mg packages). Any combination thereof is acceptable but not to exceed one ounce or the equivalent.
