Currently, there are 25 states and DC that allow medical marijuana in the United States. In the state of Pennsylvania, those who want medical marijuana must have an approved medical condition, such as epilepsy, Crohn’s disease, or PTSD.

Medical marijuana may not be dispensed to a patient in dry leaf or plant form but may only be dispensed in pill, oil, or topical forms. New guidelines for the Safe Harbor provision in the state allow parents and caregivers to administer medical marijuana obtained from outside the state of Pennsylvania. Patients receive a Safe Harbor letter, which is to be carried whenever medical marijuana is being transported outside the home.

Here’s a list of the other states that allow medical marijuana and their guidelines. This way, you can see how Pennsylvania stacks up compared to the others.
