Walgreens and Kroger are no longer selling e-cigarettes in stores.
CBS News reported that both retailers made separate statements to announce the news Monday.
The announcements come as the Centers for Disease Control and Prevention said earlier this month that more than 1,000 cases of lung injury have been reported in relation to e-cigarette use. Eighteen deaths associated with vaping have been confirmed, according to the CDC.
On Friday, the Federal Drug Administration strongly urged the public not to use any vaping products bought off the street.
