Keystone state is 24th to legalise cannabis use for health reasons, prompting state Republican senator to say: What were doing today is the healer
Pennsylvania on Sunday became the 24th US state to legalize a comprehensive medical marijuana program.
The Democratic governor, Tom Wolf, signed the bill into law in the afternoon, surrounded by a jubilant crowd of supporters at the Capitol building in Harrisburg.
Marijuana is medicine and its coming to Pennsylvania, said Democratic state senator Daylin Leach, the bills cosponsor.
The bills drafters say it could take two years to write regulations and get retailers opened, but a provision allows parents to legally administer medical marijuana to their children before the bill takes effect in a month.
The bill sets standards for tracking plants, certifying physicians and licensing growers, dispensaries and physicians. Patients can take marijuana in pill, oil, vapor, ointment or liquid form, but will not be able to legally obtain marijuana to smoke or grow.
Senator Mike Vereb, a Republican, called on lawmakers to take on what he called the No 1 killer in Pennsylvania opioid abuse.
