State health authorities Friday more than doubled the amount of medical marijuana that patients can buy, a move made after regulators determined laboratories can ensure the safety of the drug.
The state Department of Public Health had imposed a stricter limit since the first medical marijuana dispensary opened in June.
Patients will now be allowed to buy up to 10 ounces of marijuana every two months.
The changes come as two more dispensaries are poised to open.
Patriot Care in Lowell is scheduled to open Tuesday.
New England Treatment Access in Brookline sent a notice Friday to patients that the dispensary would start filling orders by appointment only.
