Can adaptogens affect your driving?

Learn how herbal supplements like ashwagandha or rhodiola may (or may not) impact DUI laws in Oregon.

Quick Takeaways:

• Adaptogens like ashwagandha and rhodiola are not illegal substances.
• Most adaptogens are not considered impairing—but effects vary by person.
• Oregon DUI laws are based on impairment, not whether a substance is legal.
• If an officer believes you are impaired, even by a supplement, you can be arrested.
• When in doubt, don’t drive until you know how a supplement affects you.

What Are Adaptogens?

Adaptogens are natural herbs and mushrooms thought to help the body manage stress, restore balance, and boost overall well-being. Common adaptogens include:

• Ashwagandha
• Rhodiola
• Ginseng
• Holy basil (Tulsi)
• Cordyceps
• Eleuthero (Siberian ginseng)

Many people take adaptogens to improve mood, energy, or focus. But like any substance that affects your brain or body, they may have unintended side effects—especially when combined with other medications or alcohol.

Are Adaptogens Considered Drugs?

In short, no. Adaptogens are sold as dietary supplements in the U.S., not as controlled substances or prescriptions. That means they aren’t tested or approved by the FDA the way medications are. However, just because something is legal or sold over the counter doesn’t mean it’s harmless—or that it can’t lead to a DUII charge in Oregon.

Some adaptogens have mild sedative effects (like ashwagandha), while others may increase alertness or energy (like rhodiola). Depending on your personal body chemistry, stress levels, or what else you’ve consumed, you might experience drowsiness, dizziness, or other changes in perception or coordination.

Oregon DUII Law: It’s About Impairment, Not Illegality

Oregon law doesn’t just cover driving under the influence of alcohol or illegal drugs. The legal term is DUII—driving under the influence of intoxicants—and that can include any substance that impairs your ability to drive safely.

This means you can technically be arrested for DUII if:

• You are impaired by a prescription drug
• You are under the influence of marijuana, even with a medical card
• You’ve consumed a legal supplement that affects your mental or physical functioning

In other words, if an officer believes you are not safe to drive, you could be arrested—even if the substance is “natural.”

What About a Blood Test?

In most DUII cases, blood or urine tests are used to detect alcohol or controlled substances. Adaptogens are unlikely to show up on standard toxicology screens.

However, officer observations and field sobriety tests can still form the basis for a DUI arrest. This is especially relevant in cases where a driver seems drowsy, slow to respond, or physically unsteady—but no alcohol or illegal drugs are found.

In addition, most officers now wear body cameras, which will capture footage of how you appear during the stop. If your case goes to trial, it could ultimately be up to a jury to decide whether you seemed safe to drive or noticeably impaired—regardless of what substances were or weren’t in your system.

How to Stay Safe (and Legal)

• Try new supplements when you’re not planning to drive. Give your body time to adjust and see how you respond.
• Avoid mixing adaptogens with alcohol or other sedatives. Even a mild adaptogen can increase drowsiness when combined with other substances.
• Be honest with your doctor and pharmacist. Some herbs interact with medications in unexpected ways.
• If you feel “off,” don’t get behind the wheel. Whether it’s fatigue, fogginess, or anything else unusual—wait it out.

Adaptogens may support wellness—but even natural remedies can create real legal risks if they impact your ability to drive. Oregon DUII law is less about what you took and more about how it affects you.
