This paper identifies the determinants affecting the adolescent populations' decision regarding whether or not to consume illegal drugs. The authors estimate a simultaneous Type II Tobit model for each sample substance, including marijuana, LSD, amphetamines, cocaine, volatile substances, and heroine. The data are drawn from three Spanish Surveys on Drug Use in the School Population conducted in 1994, 1996, and 1998. The results indicate that illegal drug use among Spanish adolescents is clearly determined by economic variables. It is similarly determined by other sociodemographic variables, such as personal habits, family environment, and the receipt of information regarding the negative consequences of drug use.
