Marijuana in the Workplace: What You Need to Know

Oct. 24, 2022

"It may seem hard to fathom, but marijuana is legalized for medical use in 34 states and the District of Columbia and 10 states - plus the District of Columbia - have legalized recreational marijuana use," according to SESCO Management Consultants. 

"Further legalization efforts will continue as marijuana use in the United States increases."

With this trend in mind, SESCO officials offer advice on how to craft drug-free workplace policies - noting that "unlike other drugs, marijuana’s precarious position between legal (states) and illegal (federal) makes it different than other impairing substances. 

Despite the wide-spread wave of marijuana legalization in the United States, marijuana remains an illegal drug on a federal basis," say SESCO officials.

"The federal government has held firm in classifying marijuana or cannabis as a schedule I drug. 

"While marijuana is illegal at the federal level in the United States, the federal government has generally chosen not to prosecute those who possess and distribute marijuana in compliance with state laws. Thus, marijuana inhabits an in-between zone of legality - legal and illegal at the same time.

"While the federal government generally does not prosecute federal marijuana possession laws, it also does not budge on treating marijuana as an illegal drug for purposes of oversight, distribution, federal disability law protection, etc.

"Further, federal requirements for drug-free workplaces still require that employees test negative for marijuana, along with other illegal drugs. This places employers in a 'no-win' situation in trying to balance federal and state laws, as well as limiting liability associated with workplace liabilities, worker’s compensation and productivity/quality expectations. 

The facts

The National Safety Council has published the following statistics, according to SESCO officials:

  • Car crashes involving marijuana went up 300% between 2010 and 2013 "and they continue to rise as more states legalize the drug;"
  • Marijuana is 10 to 20 times stronger today than it was in the 1960s and 70s; 
  • Marijuana is an addictive drug;
  • Employees who tested positive for marijuana had 55% more industrial accidents, 85% more injuries and 75% greater absenteeism compared to those who tested negative;
  • Employers spend about $7,000 per year on an employee who abuses drugs;
  • About one out of five employees "has a substance abuse problem."

In addition, a statistic from SESCO’s employee satisfaction survey "reveals that an overwhelming amount of employees (over 90%) want and expect a safe place to work. 

"These facts surrounding marijuana use cannot be simply ignored by employers as the risks and liabilities associated are significant. Regardless of the trends of marijuana use, an employer’s priority must be on providing a safe and healthy workplace for its employees, visitors and customers. 

SESCO recommendations 

"Because marijuana inhabits the in-between zone of legality - (both) legal and illegal at the same time - it is of utmost importance that all employers draft and communicate a compliant substance abuse policy to include marijuana.

"The Occupational Safety and Health Administration (OSHA) and National Safety Council both strongly recommend employers’ policies should restrict marijuana use to the extent permitted by law.

"Employers need to consider compliance to and enforcing workers’ compensation, OSHA, DOT, drug-free workplace and other legislation when drafting and communicating employment and substance abuse policies."

Policy considerations need to include: 

  • Testing for marijuana and THC, especially in safety-sensitive positions or when federal or state law requires;
  • Use a testing method such as Oral Fluid Testing, which indicates recent use as opposed to historical use;
  • In states where medical marijuana users receive protection from workplace discipline, "policies should require employees to verify their medical marijuana authorization. Additionally, employers in these states should only take adverse action against employees where the testing takes place after reasonable suspicion of impairment;"
  • Managers and supervisors should be trained carefully on how to identify impairment and what to do when an employee is suspected of impairment on the job; 
  • Policies should contain a zero tolerance (rule) for marijuana use by employees in safety-sensitive positions; 
  • Employers should carefully consider whether or not to include random testing as part of their policy; 
  • Policy should contain "immediate termination (provisions), where states allow and not provide for 'multiple chances' as the recidivism rate is in excess of 90%." 

SESCO officials also recommend that employers "always consider relevant state laws and cases" when crafting policies.
