Windsor's annual celebration of marijuana has expanded to two days and is currently underway at Charles Clark Square.
Dubbed 4-20 and 4-21, the event has attracted dozens of displays and vendors.
Organizer Leo Lucier says mild clear weather Friday and Saturday means thousands will likely attend.
He says each day has its own theme.
"The first day, 4-20 is the international day of recreational use global celebrations around the world. And 4-21 is all about medical," he says. "4-21 may be bigger than 4-20 because of the guest speakers I have coming down here. People from Los Angeles, Texas, Washington DC."

He says legalizing pot this summer won't impact his festival comparing it to gay rights and legalizing gay marriages.
"It didn't stop the gay pride parade," says Lucier.
The event will also help out a number of charities including Welcome Centre for Women and the Leamington Lodge and the food banks.
