STUDY: Marijuana use spikes among Americans over 50

People over 50 are smoking pot more than ever before.

They're outpacing all other age groups.

A study by 'New York University's School of Medicine' and 'Columbia University' found that between 2006 and 2013 marijuana use rose about 60 percent among those 50-to-64.

It increased 250 percent for those over 65.

Overall the rates increased 71 percent.

A 'News Survey' found that while marijuana use among teens is down over the past ten years, they've nearly tripled among adults over the age of 50.
