The economic and social costs of drug abuse among the rural population.

There is no doubt that drug abuse among the rural population has increased and that differences in rural/urban prevalence rates have diminished (Ennett et al. 1993; Johnston et al. 1993; Wargo et al. 1990). Some rural/urban differences remain, but many would argue that the problem is as serious—if not more serious—in rural than urban areas (Donnermeyer 1992; Edwards 1992; Kingery et al. 1991; Leukefeld et al. 1992).
