If you’ve got a child between the ages of 12 to 17, there’s a 6 percent chance that they’ve used marijuana in the past month, according to Kids Count, a national program that tracks children’s wellbeing run by the Annie E. Casey Foundation.

Young adults (18 to 25) are much more likely to use marijuana as 17 percent — or 148,000 individuals — say they used marijuana in the past month.

Fewer children — 5 percent — have smoked a cigarette in the past month. Many more young adults have smoked cigarettes, 26 percent.
