Citizens of San Francisco and Berkeley will be voting on the implementation of a soda tax in the November 2014 elections. Similar taxes have failed to garner sufficient support in the past five years, with about 30 propositions introduced and none passed, including two that went to ballot and were defeated in California in 2012.

Other countries have found more success with similar measures—among others, France and Mexico have each imposed taxes on sugary drinks. The San Francisco proposal, which needs a two-thirds vote to pass, would add a 2-cent-per-ounce tax on sugary drinks, excluding milk or natural fruit juice without added sugar, while the similar Berkeley proposal is 1-cent-per-ounce and needs only a majority of the vote.
