An Act amending the act of April 17, 2016 (P.L.84, No.16), known as the Medical Marijuana Act, in preliminary provisions, further providing for definitions.

HB 533 amends Pennsylvania's Medical Marijuana Act by updating the definition of "serious medical condition" to add autism as a qualifying condition (new item 17) and creating a new category (item 17.1) allowing practitioners to deem other conditions serious. This change directly affects patients seeking medical marijuana authorization, expanding eligibility to include autism and allowing healthcare providers to recommend additional conditions. The bill does not alter program operations, taxes, or other provisions - only clarifies which conditions qualify under the law. The amendment takes effect 60 days after enactment.
