Maryland adult-use access and personal-use amount

Maryland Cannabis Administration (MCA) guidance says adults 21 and older may possess up to 1.5 ounces of flower, 12 grams of concentrated cannabis, or cannabis products with no more than 750 milligrams THC. These are product-specific descriptions of the personal-use amount; do not combine them beyond what the current law allows. See the MCA Adult-Use FAQ.

Home cultivation is a household limit

MCA says an adult 21+ may grow up to two plants out of public view, with a maximum of two per household regardless of the number of adults there. Registered medical patients may grow additional plants, within a four-plant cap per residence. A landlord may prohibit home cultivation.

State lines and federal boundaries

MCA says cannabis may not be carried across state lines and warns that Maryland adult-use permission does not extend to federal property. Its medical rescheduling notice separately recognizes the narrow federal Schedule III change for products under qualifying state medical licenses, while saying Maryland law remains unchanged. That medical-product change is not permission for ordinary adult-use possession on federal land or interstate transport. See U.S. law overview.
