At the same time, alco hol use and other suspected determinants of psychostimulant use are investi gated and held constant, using multiple regression models. Data were taken from public use files of the 1995 National Household Survey on Drug Abuse.

This study provide s recent evidence on tobacco smoking as one of the potentially malleable ri sk factors for the nonmedical use of stimulant drugs.
