The CBD sector is growing and gaining traction as word of its potential advantages spreads globally and governments begin to adopt it. The laws on CBD are conflicting, and one of the major concerns is if one can drive under the influence of CBD Tincture.

THC, also known as tetrahydrocannabinol, is a phytocannabinoid linked to CBD. These two chemicals make up at least 40% of hemp-based cannabinoids. CBC, CBDV, CBG, and CBN are only a few of the hundreds of cannabinoids. The UK imports CBD largely from nations that grow hemp. This country has regulations governing how it is farmed, collected, and processed into CBD oil. CBD products must include less than 0.2 % THC and CBN and no more than one milligram CBD per bottle, according to UK legislation. According to Boggs et al. (2018), THC is psychoactive, meaning it interacts with CB1 and CB2 receptors in the body to produce a 'high.' Is CBD safe to drive with? This article will explore whether or not driving while using CBD Tincture is legal or safe.

Is It Legal Drive After Taking CBD

The legality of CBD oil and driving can be confusing due to cannabis, hemp, and marijuana conflation. Driving while under the influence of various substances is prohibited in the United Kingdom, and drug driving limits are set for each. Since 2015, the UK has implemented tests to detect the presence of these substances in drivers. If you are caught driving with concentrations of any substance above the legal limit, you will face harsh penalties, including:

  • A minimum of one year driving ban.
  • Unlimited fines.
  • Up to six months in prison.

In addition, being convicted for driving under illegal substances will lead to one having a criminal record. The current threshold for the various drug levels are;

  • Benzoylecgonine – 50 micrograms per liter.
  • Cocaine – 10 micrograms per liter.
  • THC – 2 micrograms per liter.
  • Ketamine – 20 micrograms per liter.
  • MDMA – 10 micrograms per liter.

CBD is not on this list. In addition, you can only have a THC blood content of up to 2g/L (two micrograms per liter) while driving in the UK. According to Hartman & Huestis (2013), exceeding this limit leads to impaired driving. However, just because driving under the influence of THC is prohibited, it does not follow that using CBD oil and driving is also prohibited. You should be able to drive legally if you use CBD oil or another CBD product sold legally in the UK. To be sold legally in the UK, a product must contain at most 0.2 percent THC concentration of 1 gram of THC per bottle. To avoid getting into trouble, it is best to consult with a legal practitioner to find out if there have been recent changes to the laws.

Is It Safe To Drive While In CBD

Researchers conducted a "real-life" study. They tested randomly selected participants (26 healthy men and women, 22 who completed the study) driving on a highway rather than using a driving simulator. The participants with an average age of 23 had used cannabis less than twice a week in the previous year but more than ten times in their lives and were not taking any medications that could impair their driving ability. Participants were assigned one of four preparations at the start of each session. After vaping, participants completed two-hour-long driving tests on a highway near Maastricht: the first between 40 and 100 minutes after vaping and the second between 240 and 300 minutes. THC preparation and THC/CBD preparation resulted in short-term impaired driving, as measured 40 to 100 minutes into the session. The impairment was comparable to drivers with a 0.05 percent blood alcohol content. (To put this in context, driving with a blood-alcohol level of 0.08 percent is illegal.) However, the CBD preparation did not affect thinking or driving abilities compared to the placebo.

These findings provide solid evidence that CBD does not impair driving or cognition. This is critical information for patients who use CBD products and regulators dealing with medical cannabis use and driving issues. It's important to recognize the study's limitations, including only one CBD dose administered via vaporization. While higher doses of oral CBD should produce similar results, this is something that needs to be investigated further. With rapidly changing attitudes toward medical and non-medical cannabis use, driving while high is an important and somewhat contentious public health issue.

Issues To Watch Out for When Driving While On CBD

While Likar et al. (2019) indicated that CBD is non-intoxicating, checking the product before driving is important. Many CBD-based products offer CBD oil. Some products contain more than the stated amount of THC, which may impair one's driving ability. Below are the key issues that one should watch out for when using CBD based products:

Certificate Of Analysis

The certificate of analysis is a document containing information about the CBD product. It shows the type of hemp used, the production process, and the CBD product's contents. It is important to watch out for the levels of THC indicated because levels above 0.2 % are prohibited and can impair one's cognitive abilities.

Third-Party Lab Reports

Gibbs et al. (2019) noted that most CBD manufacturers take their products to third-party-based laboratories to ascertain compliance. Always look out for lab reports from credible sources. This will elucidate the contents of the product you are using.


CBD has several health benefits, some of which are still being researched. In tiny doses, CBD does not appear to affect cognitive function. However, THC might affect one's driving skills; thus, the results may be slightly different. Go for items with low or no THC content to avoid putting one's life at risk and legal issues.
