New York’s attorney general is leading an effort to convince the federal government to require warning labels and child-resistant packaging for liquid nicotine after reports of accidental poisonings.

Eric Schneiderman joined his colleagues from Illinois and Indiana to write a letter urging the Food and Drug Administration to take “immediate” steps to protect children from the substance, which is used to refill electronic cigarettes. The letter, which was announced Tuesday, was signed by 30 other attorneys general from around the country.

Last year a toddler in upstate New York died after ingesting liquid nicotine and poison control centers received more than 3,700 reports of problems associated with the product.

New York already requires liquid nicotine to be sold in child-proof containers but Schneiderman says federal rules are needed.
