EHS Today Outlines Workplace Cannabis Strategies Amid Legalization

Guidance Responds to Policy Gaps Across 38 States

The publication's timing reflects a compliance crunch for multi-state employers operating in jurisdictions with divergent cannabis statutes. As of May 2026, 24 states permit adult-use cannabis and 38 allow medical programs, yet federal Schedule I classification leaves employers without uniform safe-harbor rules. EHS Today's framework addresses pre-employment screening, reasonable-suspicion protocols, and accommodation requests under the Americans with Disabilities Act.

State-by-state policy audits are essential, the guide emphasizes. Employers in California, New York, and Nevada face explicit off-duty-use protections that limit zero-tolerance policies. Texas and Georgia employers retain broad discretion to terminate for any positive test.

Impairment Testing Emerges as Key Compliance Tool

EHS Today recommends shifting from metabolite-based urine screens to impairment-detection technologies, citing the 3-30 day detection window for THC metabolites that captures off-duty use. The publication highlights oral-fluid tests and cognitive-performance apps as emerging alternatives that measure active impairment rather than historical consumption.

Several Fortune 500 firms have adopted performance-based assessments in safety-sensitive roles, according to the guide. Amazon (AMZN) and Target (TGT) removed pre-employment cannabis screens for non-DOT positions in 2021-2023. EHS Today expects the trend to accelerate as labor markets tighten.

ADA Accommodation Requests Rising for Medical Users

Accommodation requests from employees with medical cannabis cards jumped 40% year-over-year, creating liability exposure for employers who deny without documented safety justification. EHS Today cites federal case law establishing that while the ADA doesn't compel accommodation for federally illegal substances, state disability statutes in jurisdictions like Connecticut and New Jersey impose stricter employer obligations.

Individualized assessments are mandatory when medical users request modified duty or exemption from testing, the publication advises. Blanket denials risk state-law discrimination claims even where federal law provides no protection.

DOT-Regulated Industries Face Narrow Compliance Path

For employers subject to Department of Transportation drug-testing mandates, EHS Today confirms zero flexibility. Federal Motor Carrier Safety Administration and Federal Aviation Administration rules require termination or disqualification for any positive cannabis test. The guide estimates 12 million U.S. workers fall under DOT jurisdiction, spanning trucking, rail, aviation, and pipeline sectors.

DOT-covered employers should maintain separate written policies for safety-sensitive and non-regulated roles to avoid over-restricting the broader workforce, the publication recommends. That bifurcation allows companies to liberalize policies for office staff while preserving compliance in CDL-required positions.

The next flashpoint? OSHA rulemaking on cannabis-impairment standards. The agency has signaled interest in federal guidance but hasn't published a notice of proposed rulemaking as of mid-May 2026.
