Yes. Pennsylvania minors can become medical patients if they have a qualifying medical condition. However, they can only obtain their marijuana through a licensed caregiver.
Unfortunately, as an online service, we're legally not allowed to accept minors, even with parental consent.
We recommend doing a search using something like Yelp.com and the term "Medical Marijuana Evaluation" and you should have no problem finding a few MMJ doctors in your area to help.
