The strategy establishes five-year goals to reduce the rate of drug use among youths by 15%, decrease use among young adults by 10%, reduce the number of chronic users by 15%, lower the incidence of drug-induced deaths by 15%, and decrease the prevalence of "drugged driving" by 10%. In addition, the strategy identifies three challenges on which the Administration will focus this year: prescription drug abuse, which is the fastest-growing drug problem in the country; drugged driving, which recent weekend roadside surveys have found involves one in six drivers; and prevention of drug use. The strategy document notes that persons who reach the age of 21 without developing an addiction are unlikely to develop one later.
