On Saturday, tens (if not hundreds) of thousands of marijuana aficionados and supporters will take to the streets of more than 200 towns and cities around the globe in the annual Million Marijuana March pro-legalization demonstrations. Long coordinated by veteran New York City marijuana (and ibogaine) activist Dana Beal and his organization Cures Not Wars, and lately joined by Canadian "Prince of Pot" Marc Emery and Cannabis Culture magazine, the marches are now in their fourth decade.

Marches or other events will take place in most major North American and European cities, as well as numerous smaller towns and cities, especially college towns like Asheville, Boulder, and Chapel Hill. Latin America will also be represented, with rallies set for Buenos Aires and other Argentine cities, Lima, Mexico City, Rio de Janeiro, Santiago, and Sao Paulo. Kingston, Jamaica, will also be on the marijuana map this year. Capetowners will march in South Africa, and marches are scheduled for cities in Australia, New Zealand, Japan, and Israel as well.

Check out the complete list of cities to find the one nearest to you and then go out and exercise your rights. The Chronicle will be covering the event in San Francisco, and we will have scene reports from around the world next week.
