Figure 2.1 is a pie chart that shows the percentages of types of drugs used in the past month by illicit drug users aged 12 or older in 2002. The pie chart is comprised of three components. The largest of the three components is 55 percent for marijuana use only. The next largest is 25 percent for only drug use other than marijuana, and the third is 20 percent for marijuana and some other drug use.
