So, employers are faced with the dilemma of whether to test for marijuana at all when faced with the possibility of costly litigation as a result. Notably, employers have concerns regarding marijuana use and impairment at work even for employees in non-safety-sensitive positions such as those that require a sober mind and focused attention to detail (accountants, attorneys, doctors) or that entail driving (ride share, delivery).
There might be an answer to these concerns on the horizon. There are companies, such as Cannabix Technologies and Hound Labs, developing marijuana breathalyzer technologies for law enforcement and the workplace. These drug-screening devices are projected to detect THC, the psychoactive component of marijuana that causes impairment, using breath samples. Most drug tests, such as hair or urine analysis, detect THC in the system for days or sometimes weeks after consumption and long after the individual is no longer impaired. The breathalyzers are reported to show if a person has used marijuana within 2-3 hours before the test is administered, which is believed to be the peak period of impairment after the ingestion of THC. These inventive companies developed this technology in order to aid law enforcement in preventing impaired driving. But these companies also recognize and advertise the potential benefits for employers including potential cost savings in avoiding employee turnover, workplace safety benefits, and treating all employees fairly. These companies highlight the efficiency of the marijuana breathalyzers: minimal training is required; they are non-invasive and hygienic; they offer a high level of measurement sensitivity; the provide quick results onsite; they feature secure and encrypted data; and they are portable and durable. These devices may be the answer to employer concerns as the employers can say that a positive result demonstrates impairment at work rather than general past use.
As employers are considering whether to drug test for marijuana at all in the wake of these anti-discrimination laws, marijuana breathalyzers could be the ultimate long-term solution to balance employer concerns regarding a safe workplace and employees' rights to engage in legitimate conduct outside of work. However, because such devices are in the early stages of development, testing, and use, it is unclear whether they fall within the scope of the new anti-discrimination laws and whether they can be used for non-safety-sensitive positions. Because many of the anti-discrimination laws relate only to use outside of work, it appears that reliance on testing demonstrating impairment while at work would not violate such laws, but this area of the law is continuing to develop. Further, until such devices are readily available, employers who choose to drug test for marijuana must evaluate the legal risks associated with doing so on a state-by-state basis and should consult with legal counsel before doing so.
