Cannabidiol is a non-psychoactive substance sourced from industrial hemp. However, there is some misconception regarding CBD because, before the 2018 farm bill came, it was considered illegal to consume cannabis and its associated products. This has not been the case ever since the Trump administration legalized the commercial manufacturing and sale of industrial hemp, and its related products. In other words, now you can use legal CBD with THC.

Under the Agriculture Improvement Act, hemp is cannabis containing no more than 0.3% of Tetrahydrocannabinol. If cannabis has more amounts of THC than that, then it will not be regarded as marijuana.

Many people still do not know the aforesaid difference between cannabis and hemp, which essentially causes many misconceptions to exist about CBD.

Is it Considered Safe to be Behind the Wheel after Taking CBD?

Research implies that cannabidiol can help to counteract the anxiety-causing effects of Tetrahydrocannabinol (THC). However, as per the University of Sydney’s PhD candidate Thomas Arkwell, it is likely that the said research is mistranslated. Arkwell says, “There is a lot of misinformation on the internet about how CBD can modulate the effects of THC, and I worry that this information might be passed on to unsuspecting medical cannabis patients and consumers.”

Fortunately, Arkell’s study, involving some CBD- and THC-laced vapes, plus a simulated automobile driving test, gives some clarification on this matter.

In his research, 14 people vaped 0.125 grams of liquid, which was tetrahydrocannabinol-heavy or had equal parts THC and CBD. After that, every single person took part in a game of simulated driving where they should follow GPS directions on rural roads or highway. When they vaped both cannabidiol and tetrahydrocannabinol in the same concentrations, the participants often were prone to swerve much more and reported being impaired four hours afterwards.

Arkwell adds, “Our research suggests that CBD does not reduce the impairing effects of THC, at least with respect to driving, so it’s important that people are aware of this and can make their own decisions accordingly.”

Significantly, this research included no cannabidiol-only condition, which this study’s authors state was because it is “uncommon in the real world” to vape just CBD. However, the researchers found that when equal dosing of both cannabinoids was used for the participants, higher amounts of THC were in one’s blood than when the person got only THC. This suggests that the interaction between THC, CBD and driving is of possible concern in the future.
