Soda tax measures pass in 4 US cities

"Proponents hope that success in the San Francisco Bay Area will prompt other parts of the country to tax the drinks they say contribute to obesity, diabetes and other health problems. They also say it's a small price to ensure the health of children targeted by the soda industry.

Opponents, however, argued that the tax is regressive and will hurt lower-income families the most. They also claim grocers will now be forced to raise prices on other items to cover the cost. Opponents also said that it’s unfair to single out soda in the battle to fight obesity and diabetes."
