Civic Center Park 4/20 gatherings

Civic Center Park and the nearby Denver City and County Building have historically hosted annual 4/20 rallies and cannabis-related gatherings that drew large crowds and national media attention. These events, particularly around Colorado's legalization of recreational cannabis in 2012–2014, generated extensive photographs, live streams, and posts across social platforms. Policy changes and permitting have altered how and where such gatherings occur, a point often noted in online coverage.
