DENVER (AP) -- The annual 4/20 marijuana celebrations typically draw thousands to Denver's Civic Center Park. Organizers hope Denver's celebration of the drug is even bigger this year because it comes on the eve of a major national pot conference in Denver.
Tens of thousands are expected to gather in the downtown park at the annual concert, smoke-off and legalization rally.
This year's event comes the day before the annual convention of the National Organization for the Reform of Marijuana Laws, a prominent legalization group marking 40 years. This weekend's conference is drawing most Denver mayoral candidates and Colorado's Rep. Jared Polis, a Democrat who favors legalization.
Marijuana gatherings are also planned in Boulder, Colorado Springs and other cities.
