On April 17, 2016, Gov. Tom Wolf signed into law SB 3, Pennsylvania’s compassionate medical cannabis legislation. The Senate had first approved the bill on May 12, 2015, and it was subsequently revised and approved by the House on March 14-16, 2016. The Senate made technical changes to the bill and sent it back to the House on April 12, and it received final approval in the House on April 13, 2016. The law went into effect on May 17, 2016, and the Department of Health will then have six months to issue temporary regulations.
