Cities follow Philly in sugary drink tax

Four out of four cities voted to follow in Philadelphia's footsteps by passing a proposal to tax sugary drinks on Thursday.

It was on the ballot in San Francisco, Oakland and Albany, California.

Berkeley already has a soda tax.

It also passed in Boulder, Colorado.

And just as it was in Philadelphia, it was a hotly debated issue.

Supporters including former New York Mayor Michael Bloomberg and opponents spent millions of dollars on the fight.

In the end, the beverage companies lost.

Some supporters focused their message on the health benefits of a soda tax saying it'll promote healthier habits.

Studies done in Berkeley and in Mexico show increasing the price does lower consumption.

But it will take longer to see if that helps reign in problems with obesity and diabetes.
