Pittsburgh City Council on Tuesday introduced a bill that would decriminalize the possession of small amounts of marijuana, defined as 30 grams, or about an ounce.

A local activist group will gather at Point State Park Saturday in an effort to “smoke out prohibition” of marijuana.

At 4:20 p.m. Saturday, the Pittsburgh regional chapter of the National Organization for the Reform of Marijuana Laws will hold a moment of silence to protest what it calls the war on cannabis. NORML promotes repealing the prohibition of marijuana.
