Congress spent last year trying to remove intoxicating hemp products from the legal marketplace. Now lawmakers are considering a federally regulated THC beverage that would carry an unusual warning: drinking it could make you fail a marijuana drug test.

For employers, that warning captures a much bigger workplace issue.

In November 2025, Congress dramatically narrowed the federal definition of hemp. The new law generally excludes finished hemp-derived cannabinoid products containing more than 0.4 milligrams of total THC per container, threatening much of the market for intoxicating products such as delta-8 gummies and THC beverages when the change takes effect November 12, 2026.

The change also appeared likely to resolve one source of uncertainty surrounding workplace marijuana testing . Employees who tested positive for THC could point to federally lawful hemp products as a possible source. Once many of those products lost their status as legal hemp, that explanation would become less persuasive.

But before the new restrictions have even taken effect, Congress is reconsidering its approach.

Congress Reconsiders The 2025 Approach

Lawmakers have introduced competing proposals to delay, repeal or replace the new restrictions. The Senate has also approved a short extension that would postpone most of them until December 11, although that extension has not become law.

Another approach would preserve a legal market for some intoxicating hemp products through federal regulation.

On August 10, Reps. Beth Van Duyne, R-Texas, and Greg Landsman, D-Ohio, introduced the bipartisan Beverage Regulatory Parity Act . The bill would create a federal regulatory framework for hemp-derived beverages containing up to 5 milligrams of intoxicating THC per serving.

The proposal borrows from alcohol regulation. Sales would be limited to people 21 and older, manufacturers would face testing and labeling requirements, synthetic cannabinoids would be prohibited, and states could impose stricter rules or ban the beverages entirely.

One proposed labeling requirement is particularly relevant to employers: consumers would have to be warned that drinking a hemp-derived beverage may cause them to fail a drug test for marijuana.

A Legal THC Product And A Positive Drug Test

Consider the potential scenario.

An employee buys a federally lawful THC beverage, consumes it while off duty and later tests positive for marijuana under an employer's drug-testing program.

The product was legal. The test was positive. Was the employee impaired at work?

Those questions do not necessarily produce the same answer.

Depending on the testing method, a positive THC result can establish prior exposure without necessarily establishing impairment when the specimen was collected. Some states have already incorporated versions of that distinction into their employment laws.

New York generally protects lawful off-duty cannabis use, subject to exceptions, and allows employers to act when employees exhibit specific articulable symptoms of impairment at work. State guidance expressly cautions that a cannabis test alone cannot establish impairment.

Washington takes a different approach, generally restricting employers from making initial hiring decisions based on lawful off-duty cannabis use or certain preemployment cannabis test results, with exceptions including specified safety-sensitive positions and federal requirements.

Minnesota also provides employment protections involving certain lawful cannabis and hemp products while preserving employer authority in specified circumstances.

A federally lawful intoxicating hemp product could add another variable to this already fragmented landscape.

Congress appears to recognize the underlying challenge. The Beverage Regulatory Parity Act would direct federal agencies to study how to measure and distinguish impairment associated with hemp-derived beverages, including impairment affecting motor vehicle operation.

That provision is telling. Congress is considering a federally regulated intoxicating THC product while acknowledging that determining impairment from its use remains a difficult question.

DOT-Regulated Employees Remain Different

The analysis is more straightforward for workers subject to Department of Transportation drug-testing requirements.

DOT continues to require marijuana testing for safety-sensitive employees. The agency has also made clear that a Medical Review Officer cannot verify a laboratory-confirmed marijuana-positive result as negative simply because an employee attributes the result to marijuana obtained through a state-authorized program.

A federally lawful hemp beverage would present a different factual situation. But the Beverage Regulatory Parity Act would not amend DOT's drug-testing regulations or create an exception for a positive result attributed to a hemp-derived THC beverage.

Commercial drivers and other DOT-regulated workers therefore should not assume that legal availability of a THC product means they can consume it without potential workplace consequences.

That distinction could become increasingly important if federally regulated THC beverages eventually appear alongside beer and other adult beverages on store shelves.

What Employers Should Do Now

Employers do not need to rewrite their drug-testing policies based on proposed legislation. The 2025 hemp restrictions remain law, and Congress has not settled on an alternative.

The debate does provide a useful reason to examine what existing policies actually regulate.

Employers should understand whether their policies distinguish among substance use, a positive drug test and workplace impairment. Multistate employers should identify jurisdictions that restrict marijuana testing or protect lawful off-duty use. Employers with DOT-regulated or other federally regulated workers should continue treating those populations separately where federal rules require it.

Employers should also consider how they would handle an employee who attributes a positive marijuana result to a legally purchased hemp product. That question may implicate the employer's policy, the testing method, applicable state law and the employee's job duties.

Most importantly, employers should avoid assuming that the legal status of a product determines the employment consequences of using it.

Congress may ultimately preserve last year's restrictions, delay them or create a regulated pathway for some intoxicating hemp products. Whatever lawmakers decide, the workplace question will remain.

A substance can be legally available. An employee can test positive for THC. Neither fact, standing alone, necessarily establishes workplace impairment .
