Legal but Risky: The use of THC may lead to a positive drug test result and cause unemployment

Meet Jake, who thought he was being responsible by purchasing a Delta-8 THC product from his local convenience store. It’s legal in 22 states, and he was just using it to relax after work. A few months later, Jake was blindsided when he failed a routine drug test at his job and was subsequently fired. His “legal” product had led to a positive drug test result. Jake’s story isn’t unique—many employees are finding themselves in similar situations, using THC products that are technically legal but still facing the consequences of failing a drug test.

Are you one of those people who think Delta-8 and other THC products won’t affect your job? Think again. As these products become more widely available, employees are encountering a new challenge: the conflict between legal THC products and workplace drug policies. In this post, we’ll explore how these products impact drug testing, from the perspective of a professional drug testing company.

The Types of THC and How They Affect Drug Tests

First, what exactly is THC? Most people know it as the primary psychoactive compound in cannabis, but THC isn’t just one molecule. In fact, there are several types of THC, including Delta-8, Delta-9 (the most well-known form), THCA, and others.

Here’s the catch: all types of THC can lead to a positive result on an employment-required drug test. Standard workplace drug tests don’t differentiate between the various forms of THC. So, if you use a “legal” Delta-8 product, you could still test positive for THC, putting your job at risk. Even though Delta-8 might be legal where you live, that doesn’t make it safe for workplace use—especially if your employer has strict drug testing policies.

For instance, you might purchase a Delta-8 product that meets legal requirements, but if you use it regularly, your body could accumulate enough THC to trigger a positive drug test. Even low-THC products can result in a positive test depending on factors such as usage frequency and your body’s ability to metabolize THC.

While you may argue that you’ve only used a legal product like Delta-8 and haven’t consumed it recently, remember that THC can remain in your system for days—or even weeks—after use. For frequent users, THC can build up in the body, leading to a positive test result long after the effects have worn off. The amount of time THC stays detectable in your system depends on factors such as your metabolism, body fat, and usage frequency.

Note: There are no definitive studies that specify how much THC can be consumed over a given period without the risk of testing positive. This uncertainty means that even infrequent users of Delta-8 or other low-THC products could face unexpected test results.

In some cases, employers may request comprehensive drug tests capable of detecting substances in your system for up to 90 days.

Overall, we strongly recommend meeting with your employer to clarify their regulations regarding drug use. Keep in mind that many laws explicitly uphold an employer’s right to enforce zero-tolerance workplace drug policies (University of San Francisco School of Law).
