More baby boomers smoking marijuana

A growing number of baby boomers are acting like teenagers again, using marijuana.

The difference now, is that older Americans appear to be smoking joints to ease their aching joints, or other ailments.

A study from New York University shows 9% of people in their 50's and early 60's use cannabis.

That's up from less than 5% more than a decade ago.

Those who smoked as teenagers were more likely to take it up again as older adults.
