Comparing medical and recreational cannabis use among employees

Abstract

Nearly one in five US employees reports having used cannabis in the past year. As policies and laws regarding cannabis use rapidly change, concerns have arisen over employees' use of cannabis, for both medical and recreational purposes. While extant workplace research has not distinguished between types of cannabis users, other studies have found that medical users are clinically and socio-demographically different from non-medical users. This study utilized a sample of employed National Survey on Drug Use and Health (NSDUH) respondents to examine differences in workplace characteristics and health outcomes among employed medical, recreational, and mixed-use cannabis users. While some differences were initially seen when examining health and work-related outcomes between the groups, several changed after controlling for other important health-related factors. One key difference between the user groups is the higher percentages of medical and mixed-use cannabis users in the construction and mining industries. This study discusses future research needs, as well as practical implications for workers and employers.
