This study, using data from the British Crime Survey (BCS), examines the ef
fect of drug use on occupational achievement. It starts by attempting to ov
ercome the identification problem that results from the limited set of drug
use questions presented in the BCS. Taking this into account, and allowing
for the endogeneity of drug use in equations for unemployment and labour m
arket outcomes, that a mild positive association with 'soft' drugs and occu
pational achievement is observed that diminishes with age. This relationshi
p holds for males but not for females. In contrast, it is also found that p
ast use of 'hard' drugs significantly increases the likelihood of current u
nemployment, although it appears to be unrelated to occupational success, c
onditional on achieving employment.
