Melania Trump is calling on companies to stop marketing e-cigarettes to children, saying they're addictive and dangerous.

The first lady - who has a 13-year-old son, Barron - says teenagers and young adults must be encouraged to admit addiction, including to electronic cigarettes and vaping - and get help.

She adds: "Marketing this addictive product to children must stop."

Mrs. Trump spoke Monday at a U.S. Drug Enforcement Administration rally in the Washington area to help reinforce an anti-drug message before an annual drug-free week begins Oct. 23.
