The prevalence of past month marijuana use among adolescents (i.e., youths aged 12 to 17) generally decreased from 2002 (8.2 percent) to 2005 (6.8 percent), and then remained constant between 2005 and 2007. The percentage of adolescents who perceived great risk from smoking marijuana once a month increased between 2002 (32.4 percent) and 2003 (34.9 percent), and then remained relatively stable between 2003 and 2007. Adolescents who perceived great risk from smoking marijuana once a month were much less likely to have used marijuana in the past month than those who perceived moderate to no risk (1.4 vs. 9.5 percent).
