Drinking and smoking as concurrent predictors of illicit drug use and positive drug attitudes in adolescents

The study investigates the relationship between smoking and drinking, and the use of illicit drugs in a cohort of London adolescents. A high prevalence of drug experimentation and positive attitudes to illicit drug use were characteristic of those who both drank alcohol and smoked cigarettes on a regular basis. There was then a clear hierarchy in which lower prevalence of use and more negative attitudes marked those who only smoked, then those who only drank, while non-smokers and non-drinkers (the largest group) had lowest lifetime and recent drug use prevalence and the most negative attitudes about drug use.
