At any one time, every patient in Oregon may have 24 ounces of dried, usable medical marijuana in his name. That means all of your dried, usable medicine, where ever it is being stored, must not exceed 24 ounces at one time. That does not mean that you can have 24 ounces at your house, another 24 ounces at your caregiver’s home, and another 24 ounces at your grower’s location.
You may also have, at your designated grow site, up to 6 mature medical marijuana plants and up to 18 starts or seedlings. State law defines a mature medical marijuana plant as ANY plant which is taller than 12 inches, more than 12 inches around at the widest part of the canopy, or in bud (flower).
