This paper uses a dataset collected among inhabitants of Amsterdam, to study the employment effects of the use of cannabis and cocaine. For females no negative effects of drug use on the employment rate are found. For males there is a negative correlation between past cannabis and cocaine use and employment. However, after correcting for the effect of unobserved personal characteristics there is no negative effect of cannabis use or cocaine use on the employment status of males.
