Illinois lawmakers are pushing for legislation that childproofs electronic cigarettes. State Representative Robyn Gabel proposed the bill. Her measure would allow the Illinois Department of Public Health to set standards for the packaging of e-cigarette liquid, or e-liquid, refills, which contain concentrations of nicotine in liquid form. It can cause acute nicotine poisoning if ingested, inhaled or absorbed into the skin or eyes. The Senate is expected to consider the measure by the end of the month.
