The purchasing limit for Massachusetts MMJ patients is 10 ounces every 60 days. This is a "rolling-day" schedule. This means that if a patient was to buy all 10 ounces in one trip, they would need to wait another two months before purchasing any more marijuana.

So long as Massachusetts patients keep their total purchases under ten ounces in this period, they can frequent dispensaries or make purchases as often as they please. Keep in mind that his purchasing limit applies to all medical marijuana products, including edibles and concentrates. And it’s important to note that not every gram of marijuana product is treated equally. One gram of concentrates, for example, is viewed as the equivalent of 5.3 grams of cannabis flower.
