CBD and driving: what retailers should know about roadside drug tests

By Manon, CBD specialist at Deli Hemp Pro

Customers regularly ask whether they can drive after using CBD. The honest answer has two parts. CBD itself does not produce the effects of THC and is not what drug-driving laws target. But standard roadside tests do not tell a legal CBD product apart from cannabis, and many CBD products contain traces of THC. That is the point a retailer needs to explain.

CBD and THC: why the difference matters behind the wheel

CBD, or cannabidiol, occurs naturally in the cannabis plant. It is usually extracted from industrial hemp, varieties bred to contain very little THC, and turned into oils, capsules, extracts and other formats, as well as sold as CBD flowers. It does not alter consciousness or cause euphoria.

THC is a different story. It is the compound behind the euphoric effects of cannabis: it acts on the endocannabinoid receptors in the brain and changes perception, mood, memory and coordination. That is why driving under the influence of THC is considered dangerous, and why it is an offence in most countries.

What does the law say about CBD and driving?

The legal status of CBD varies from one country to another, and sometimes from one region to another. In many countries, CBD from industrial hemp with very low THC is treated differently from cannabis with higher THC levels, which faces restrictions.

Drug-driving laws, for their part, target psychoactive substances, THC included. In most cases it is an offence to drive with a THC concentration in the blood above a set limit. CBD without THC is generally not regarded as a psychoactive substance and is not what these laws are aimed at.

In France, where we are based, our products comply with French law (delta-9-THC ≤ 0.3%). That says nothing about other markets: the status of hemp products varies between countries and can be much stricter, and in the UK the status of hemp flower is still contested. Check the rules for resale where you trade before you order.

Can CBD show up at a roadside check?

This is where customers get caught out. Standard roadside screening tests do not distinguish between CBD and THC: they detect the presence of cannabinoids in the body rather than identifying a particular product. A CBD product that contains traces of THC can therefore carry a risk for a driver, even when it is perfectly legal to sell.

Rules on CBD and on roadside testing keep changing. The right advice at the counter is not a promise. Tell customers who drive to check the law where they live and to ask a doctor or a lawyer if they need a specific answer.

Which THC-free CBD products to offer drivers

For customers who drive, the most cautious choice is a product formulated to contain no THC, backed by a lab report that shows it. Our THC-free CBD resins fall into this category, for example the Ketama 25% CBD THC-free resin. Among the other formats, CBD oils are the ones customers ask about most.

Whatever the format, buy from a traceable source and make sure each batch has been lab-tested, so you can show the THC content to anyone who asks. As a CBD wholesaler, Deli Hemp supplies the batch analysis with its products; if a report is not on the product page, ask your sales contact for it. Browse our CBD products to compare formats.

Frequently asked questions

Is it legal to drive after using CBD?

Drug-driving laws target THC, not CBD as such. The risk comes from THC traces in some CBD products, which roadside tests can pick up. Rules differ by country, so drivers should check the law where they live.

Can a THC-free product guarantee a negative roadside test?

No seller can guarantee a test result. A product formulated without THC, with a batch report confirming it, is the most cautious option. Keep the report to hand so you can show it to customers.
