While 4/20 was a shadow of its former self, Colorado still saw a range of private smoke sessions and parties, parking lot celebrations, pot-friendly classes and celebrity streaming events all in the name of the world's favorite cannabis holiday.

And some of the action will continue this week. Here's how you can still celebrate:
