It's late Saturday night. A group of friends order a pizza and gather on a screened porch to light up. It isn't tobacco.
They use a bubbler, a pipe with a water chamber, which is supposed to make the effects of the marijuana last longer.
These friends are not isolated cases. A May 2012 study by the Partnership at Drugfree.org found that 27 percent of teenagers nationwide said they used marijuana within the previous month, a 42 percent
increase from 2008. Nine percent of teens said they used marijuana 20 or more times the previous month, up 80 percent.
