In 2023, the U.S. witnessed a significant trend: 8.3 million Americans became registered medical cannabis cardholders, while approximately 17% of the population engaged in cannabis use. This upward trajectory in cannabis consumption has prompted a legislative response from several states aimed at safeguarding the employment rights of individuals who use cannabis, whether for medical or recreational purposes. The underlying challenge is the enduring detectability of THC—the psychoactive element in cannabis—which can linger in the body for up to 30 days post-consumption, potentially leading to adverse employment consequences for individuals who are not impaired at work.
