DiCaprio leaves American Lung Association upset by smoking vape pen

Washington D.C : Leonardo DiCaprio might have bagged an SAG award, but he has upset the American Lung Association by smoking an e-cigarette at the ceremony.

The 41-year-old actor was seen sitting at a table during the awards presentation on January 30, smoking a vape pen, reports TMZ.com.

It is illegal to smoke vape pens in the city of L.A. in restaurants, bars and other public places, but interesting, the prohibition does not apply to theatrical production sites.

However, the American Lung Association is now calling out on 'The Revenant' star by tagging his conduct deeply troubling.

DiCaprio has not recated on the issue yet.
