Couch Locked by Cookies attendees enjoy the outdoor set. (via Couch Locked Network) Stoner Christmas came and went yesterday, with the presents gone as fast as they were opened. Millions of cannabis fans in the US, and millions more worldwide, packed bowls, laughed at comedy shows, live-streamed a concert or two, or just watched a movie for the unofficial stoner holiday of 420. Weed sessions started before dawn in the East Coast time zones and went on after dark in the West. While most celebrated at home, a few scattered public events helped make the second pandemic 420 memorable. The stoner code for “time to get high” 420 began 50 years ago this year, slowly morphing over the decades from an underground signal to a cultural rallying cry for cannabis liberation.
