A man walks past a medicinal marijuana dispensary in Los Angeles,CA on November 2, 2010. Californians will vote today on whether to make their famously laid-back US state the world's first to legalize all marijuana consumption, cultivation and trade. Growing and selling marijuana for medicinal purposes has been legal here since 1996, but a hard-fought referendum held the same day as congressional and gubernatorial races would take it a step further. Proposition 19 -- one of a series of referendums held on November 2 -- would allow people aged 21 and over to possess up to one ounce (28 grams) of marijuana and grow up to 25 square feet (2.32 square meter) of pot plants.
