Amazing that such a law could be passed in the first place. From Alternet.

Challenges by Pennsylvania citizens and townships on provisions in the law that prohibit doctors from telling patients about health impacts related to fracking chemicals were sent back to Commonwealth Court for reevaluation. The “physician gag order” (or “ frack gag“) was recently challenged by a doctor who claimed it infringed on his First Amendment rights and his duties as a doctor, but his challenge was thrown out by a Pennsylvania court in October. The Supreme Court’s decision to send the Commonwealth Court’s decision back down for re-evaluation spells trouble for the gag order. Doctors have expressed concern over this rule in Pennsylvania and what it means for their patients — a report from Pennsylvania documented a range of health problems affecting residents living near natural gas operations, including skin rashes, headaches and chronic pain.
