Missouri House members have given first-round approval to legislation that seeks to prevent children and younger teens from buying electronic cigarettes and other devices.
E-cigarettes are battery-powered devices used to heat a liquid nicotine solution and create vapor that is inhaled.
Missouri's legislation would prohibit sales to anyone younger than 18 years old. The bill was approved by voice vote on Tuesday and needs another affirmative vote before moving to the state Senate.
The federal Food and Drug Administration has said it plans to set marketing and product regulations for electronic cigarettes in the near future but hasn't done so yet.
