In September, Tammy Cohen, PHR, SHRM-CP, discussed marijuana legalization, one of the most common news topics today. Considered a Schedule I drug since 1970, at the time of her column more than 30 states and the District of Columbia had legalized its use in some form. Attitudes continue to shift since the Controlled Substances Act (CSA), with one poll revealing that 83 percent of people are in support of the legalization of medical marijuana, while 64 percent are in favor of its legalization in medical and recreational form. Employers find themselves challenged with whether or not to accept the changes within the workplace. In states where it is recreationally legal, workplaces should maintain a drug-free workplace and forbid its use during work hours. The laws and legal statutes, however, are murky regarding what employers are able to enforce while users are “off the clock.” Laws regarding medical marijuana vary, from anti-discrimination laws to employers enforcing a drug-free environment.
