An Act amending the act of April 17, 2016 (P.L.84, No.16), known as the Medical Marijuana Act, providing for compassionate access to medical marijuana; and imposing a penalty.

Expanded the list of facilities allowed to permit medical marijuana use to include psychiatric hospitals, behavioral health crisis centers, medical detox facilities, and rehabilitation centers.

Added liability protection stating that facilities and employees acting in good faith are not subject to criminal, civil, or administrative liability for injuries resulting from patient use unless gross negligence or willful misconduct occurs.

Changed the effective date for the new Section 1402 to 270 days after enactment, while the rest of the act takes effect in 90 days.

Added a new requirement that medical marijuana must not be vaporized, smoked, or ingested in any form that could impact care to other patients.

Clarified that facilities may suspend compliance with the chapter only if a federal agency notifies them they can resume permitting use, rather than automatically suspending compliance.
