Congress has passed legislation to require child-resistant packaging for the liquids that give e-cigarette both their kick and their flavor, according to a news report by USA Today.

The House of Representatives passed the bill Monday by a voice vote. The Senate approved the measure last month. The bill now goes to President Obama, who is expected to sign it.

“A few drops of this stuff can cause a child to become extremely ill,” said Senator Bill Nelson (D-Fla), who supported the bill.  “Requiring child-proof caps on these bottles is just common sense.”
