Does Kratom Affect Driving? A 2024 Study Has Surprising Answers

For years, kratom consumers have said the plant helps them stay focused, productive, and level‑headed throughout the day. But one question keeps coming up — does kratom affect driving?

A 2024 peer‑reviewed study published in Traffic Injury Prevention finally gives us real data, and the results are far more reassuring than many expected.

This research is one of the largest and most detailed investigations ever conducted on kratom and driving. It included:

• 357 regular kratom users in a national survey and 15‑day ecological momentary assessment (EMA)
• 10 kratom‑experienced adults completing a controlled, high‑fidelity driving simulator test before and after taking their typical kratom dose

Below, we break down what the scientists found — and what it means for kratom consumers today.

Key Takeaway: Regular Kratom Use Did Not Impair Driving Performance

Across both phases of the study, researchers found no significant signs of driving impairment after kratom use among regular consumers.

In fact, the study states:

• “Participants reported feeling confident in their driving ability and perceived little impairment within 15–180 minutes after using kratom.”
• “There were no significant changes in simulated driving performance after taking kratom.”

This is a big deal. It’s the first controlled research showing that self‑selected, typical kratom doses did not negatively affect driving ability in people who use kratom regularly.

What the National Survey Revealed

The survey portion of the study included 357 kratom users across the U.S. Here’s what researchers found:

1. Over 90% of users have driven after taking kratom

This doesn’t mean they should — but it does show how common kratom use is as part of daily routines.

2. Users reported very low risky driving behaviors

Most participants said they “rarely” or “never” engaged in dangerous driving habits like speeding, tailgating, or aggressive maneuvers.

3. Users felt highly confident driving after kratom

Across all groups, driving confidence scores averaged 96–98 out of 100.

4. Perceived impairment was extremely low

During the EMA portion, users consistently reported minimal impairment after kratom use.

This aligns with what many kratom consumers already experience: kratom tends to support focus and calmness rather than intoxication.

What the Driving Simulator Test Showed

The second part of the study is where things get really interesting.

Ten regular kratom users visited a Johns Hopkins–affiliated lab and completed:

• A baseline driving simulation
• Their typical kratom dose (1.1g–10.9g depending on their routine)
• A second driving simulation during peak kratom alkaloid levels

The simulator measured:

• Lane weaving
• Reaction time
• Speed control
• Crash avoidance
• Divided attention
• Rule following

The results?

No meaningful differences between pre‑kratom and post‑kratom driving performance.

No increase in:

• Lane drifting
• Slow reaction times
• Missed signals
• Speeding
• Collisions

Only one participant showed a slight decrease in performance on one task — but not across the board.

What This Means for Kratom Consumers

This study is a major step forward in understanding kratom’s real‑world effects. Here’s what we can reasonably conclude:

✔ Regular kratom users did not show impaired driving

✔ Typical self‑selected doses did not reduce reaction time or attention

✔ Users felt confident and capable behind the wheel

✔ Kratom’s effects appear more similar to caffeine than intoxicants like alcohol or cannabis

The researchers even note that kratom is often used “to enhance productivity, focus, and energy,” not for intoxication.

Important Notes and Limitations

The study is promising, but it’s not the final word. Researchers emphasized:

• Results apply to regular kratom users, not first‑time or inexperienced users
• Higher doses or extracts were not tested
• Only raw powder products were used
• The sample size for the simulator portion was small (N=10)
• No placebo control was included

So while the findings are encouraging, more research is needed, especially for infrequent users or those combining kratom with other substances.

The Bottom Line

This 2024 study provides the strongest evidence to date that typical kratom use does not impair driving performance in regular consumers.

For millions of Americans who use kratom daily for energy, mood, or relief, this research supports what they’ve been saying for years: kratom helps them function — not lose control.
