Baby-boomers skew drug figures

The percentage of people between 50 and 59 using illegal drugs in the U.S. rose from 5.1% in 2002 to 9.4% in 2007. The near doubling of the rate is probably due to the "baby-boomer" generation moving into this age bracket and contrast with static or declining use in other age brackets. The rate of drug use among 18-25 year-olds fell over the same period from 20.2% in 2002 to 19.7% in 2007, while usage among 12-17-year-olds fell from 11.6% to 9.5%.
