THC-Infused Drinks and Products: What Employers Need to Know for a Drug-Free Workplace

Cannabis products have changed dramatically over the past few years. Today, THC can be found in beverages, gummies, chocolates, mints, baked goods, tinctures, capsules, vape products, and even products derived from hemp, such as Delta-8 and Delta-9 THC beverages. Because many of these products look like everyday food or drinks, employees may not recognize—or may underestimate—their potential to cause impairment.

For employers committed to maintaining a safe, productive, and compliant workplace, understanding these newer cannabis products is becoming increasingly important. THC-infused beverages contain tetrahydrocannabinol (THC), the psychoactive ingredient in cannabis that produces the "high." Unlike alcoholic beverages, THC drinks often resemble sparkling water, soda, lemonade, iced tea, energy drinks, or flavored seltzers. Many products advertise low doses such as 2.5 mg or 5 mg per serving, while others contain 10 mg or more. Some beverages contain multiple servings in a single container, making it easy for consumers to unintentionally consume more THC than intended. Although many products are marketed as a healthier alternative to alcohol, they can still impair judgment, reaction time, coordination, attention, and decision-making.

Unlike smoking or vaping cannabis, THC consumed through food or beverages is absorbed through the digestive system. This creates two important concerns:

• The effects take longer to begin—often 30 minutes to 2 hours after consumption.

• The effects can last significantly longer, sometimes six hours or more, depending on the individual, dosage, metabolism, and whether food was consumed.

Because the effects are delayed, individuals sometimes believe the product "isn't working" and consume additional servings. This can lead to much stronger impairment than expected.

An employee may consume a THC beverage during lunch, after work the previous evening, or before arriving at work without realizing the timing or duration of impairment.

For employers, this presents several challenges:

• Slower reaction times

• Reduced concentration

• Poor judgment and decision-making

• Impaired coordination and balance

• Increased risk of workplace injuries and near misses

• Greater safety concerns for employees operating vehicles, machinery, or performing safety-sensitive tasks

The CDC notes that employers across all industries are facing increasing challenges related to cannabis use and workplace impairment, particularly in safety-sensitive positions.

Many consumers assume products labeled as "hemp-derived" are non-psychoactive. However, this is not always true. Some hemp-derived products legally contain intoxicating forms of THC, including Delta-8 THC and hemp-derived Delta-9 THC. These products can produce many of the same impairing effects as traditional cannabis products.

One of the biggest misconceptions is that employers can determine whether an employee is currently impaired through a traditional drug test. Most workplace drug tests detect THC metabolites, which indicate prior use but generally do not establish current impairment. This is why employers should have comprehensive policies that address workplace impairment, supervisor observations, reasonable suspicion procedures, and employee education—not drug testing alone.

As cannabis products continue to evolve, employee education becomes more valuable than ever.

Employees should understand:

• What THC-infused beverages and edible products are

• How delayed onset can increase the risk of overconsumption

• That legal products can still cause impairment

• Company expectations regarding reporting to work fit for duty

• The consequences of working while impaired

• Resources available if substance use becomes a concern

  
  

Research and workplace safety organizations continue to emphasize that education, combined with clear policies, helps employees understand not only what the rules are, but why they exist.

As cannabis products become more accessible, employers should review their Drug-Free Workplace Program to ensure it reflects today's workplace realities.

Consider the following:

• Review your drug-free workplace policy.

• Train supervisors on recognizing and documenting reasonable suspicion.

• Educate employees about modern cannabis products, including beverages and edibles.

• Reinforce expectations that employees report to work fit for duty.

• Provide access to Employee Assistance Program (EAP) or other community resources when appropriate.

• Review state and federal laws applicable to your workforce, particularly if you employ safety-sensitive or DOT-regulated workers.

  
  

THC-infused drinks and edible cannabis products are becoming increasingly common, but their growing popularity does not reduce the importance of workplace safety. Whether THC is consumed through a beverage, gummy, or other edible, impairment can still affect an employee's ability to perform work safely. Employers who combine strong policies, consistent education, supervisor training, and clear expectations are better positioned to protect their employees, reduce risk, and maintain a safe and productive workplace.

Together, we can help build a safer, healthier, and more productive workplace.
