(AP) — The city of Berkeley is considering what would be among the nation's strictest buffer zones for tobacco products, as it tries to keep them away from schoolchildren. The city is set to vote next month on an ordinance that would prohibit the sale of tobacco products within 1,000 feet of a school or public park, the San Francisco Chronicle reported on Saturday (http://bit.ly/1DUxogw ). Councilwoman Linda Maio said she hopes the tobacco buffer zones will end youth smoking and discourage casual adult smokers.
