“…Many studies have examined the effects of drug use on employment, and the evidence indicates that drug use, especially chronic or “hard” drug use (Alexandre & French, 2004; French, Roebuck, & Alexandre, 2001; Newcomb & Bentler, 1986), has a negative impact on work performance, labor force participation, job retention, and earnings (Baldwin, Marcus, & De Simone, 2010; Braun et al, 2000; Bryant, Jayawardhana, Samaranayake, & Wilhite, 1996; Gill & Michaels, 1992; Hoffmann, Dufur, & Huang, 2007; Kandel & Davies, 1990; Marie, Fergusson, & Boden, 2008; Mink et al, 2008; Naccarato et al, 2010; Ringel, Ellickson, & Collins, 2006; Wiesner, Capaldi, & Kim, 2010; Wu, Schlenger, & Galvin, 2003).
