Marijuana in the workplace is a growing challenge for employers. More and more states allow its use, for medical and recreational purposes, while federal law still does not permit it.

Research cited by the National Institutes of Health (NIH) links marijuana use with workplace problems such as injuries and accidents. In one study of postal workers, employees who tested positive on a pre-employment urine test had 55 percent more industrial accidents, 85 percent more injuries and 75 percent more absenteeism than those who tested negative.

This 60-minute webinar summarizes the challenges of managing employee marijuana use, explains the relevant law, describes testing devices for impairment, and reviews recent court cases. Defining what it means to be under the influence is hard, and accurate measurement methods are only starting to emerge.

WHY SHOULD YOU ATTEND?

Employers most often ask two questions: how to handle an employee who presents a medical marijuana card during drug screening, and what recreational legalization means for a drug-free workplace policy. The answer depends on the state, whether use is medical or recreational, how recently the person used it, the safety demands of the job, and company policy.

This session helps leaders, managers and HR professionals work through those factors and finishes with practical advice.
