How CBD and THC Have an effect on Your Driving, In response to Landmark Research
A study published Tuesday suggests that low doses of CBD have no impact on people’s ability to drive. It was also found that while THC can affect drivers, the effects wear off within four hours.
The study, published in the Journal of the American Medical Association, is the first to analyze the effects of CBD on driving and provides more information on how THC affects us behind the wheel.
“These results show for the first time that CBD, when administered without THC, does not affect a subject’s ability to drive. This is great news for those who are using or considering treatment with CBD-based products, ”said lead study author Dr. Thomas Arkell.

The researchers looked at 26 healthy adults who were randomly given four different types of inhaled vaporized cannabis. The cannabis administered consisted of various mixtures of THC, CBD and placebo cannabis with no active components. These volunteers were then asked to drive on a public highway for about an hour in controlled but realistic conditions and to drive a double-checked car next to a driving instructor. Participants had to run two separate drives, one after 40 minutes of usage and the other four hours after usage.

The results showed that subjects who consumed strains made from pure CBD were not impaired at any point during the journey. However, subjects who consumed strains of CBD and THC or pure THC showed a slight impairment 40 minutes after consumption on their first trip. When these test subjects made their second trip four hours after eating, there was no noticeable impairment.
“As cannabis laws change around the world, jurisdictions are grappling with the problem of cannabis-impaired driving. These results provide much-needed insight into the extent and duration of harm caused by different cannabis strains and can help guide road safety policy not just in Australia but around the world, ”said Dr. Arkell.

Driving under the influence of THC has been a much debated topic, especially now as more states legalize recreational use. Industrial manufacturers are working on devices that can measure THC poisoning, but the technology doesn’t yet exist. In the meantime, more information and study is needed to learn more about the subject, correctly measure the amount of THC that is personally present, and provide guidance on how to deal with them if caught driving.
