Whenever a state legalizes medical or recreational marijuana, there's usually some growing pains. But in Pennsylvania, those pains are being felt right away.

Medical marijuana dispensaries in Pennsylvania are already running out of supply less than two weeks after sales began in the state. Two dispensaries near Philadelphia said they don't expect to begin selling again until March 15th at the earliest, and have closed shop entirely.

There are a few reasons for this lack of supply. The chief reason is that only one of Pennsylvania's 12 licensed marijuana growers is actually shipping product to dispensaries. So essentially the state is attempting to serve all its customers with 1/12th of the possible supply. Two other growers are expected to begin shipping by the end of the month.

The other is unexpected demand. One Philadelphia dispensary expected 60 customers in its first month in operation. They had over 600 in the first eight days. 

Two more dispensaries are set to open in the next few weeks, and another is expected in mid-April. 

Obviously, these kinks will be ironed out once all the growers in the state are operational and at full capacity. Until then, Pennsylvania medical marijuana customers will have to be patient.
