Supporters of a coming ban on the sale of flavored tobacco products in California asked the state attorney general on Tuesday to investigate complaints that people gathering signatures for a referendum to overturn the law have misrepresented the effort. [...] “In several instances, petition circulators for this referendum have approached voters and asked them to sign this petition under the pretense that signing the petition would support banning flavored tobacco,” attorney Lance Olson wrote. “This is categorically false, as this referendum seeks to overturn the law prohibiting the sale of flavored tobacco products.”
