First Things First. Is CBD Oil Actually Legal?

Yes, CBD oil is legal in the UK to those above the age of 18 as long as it:

  • Contains less than 0.2% THC, a controlled substance under the Misuse of Drugs Act 1971
  • Comes from a strain of industrial hemp that is EU approved

Looking for a safe, trusted and reliable brand? All CBII products contain less than 0.2% THC guaranteed and are independently tested to verify THC and CBD content.

Our credentials: Our CBD is also sourced from legally and ethically grown plants in the EU adhering to strict Good Agricultural and Collection Practices (GACP) and accredited European GMP manufacturing standards.

Is CBD Oil Safe To Use?

CBD products are classified as food supplements that are safe for human usage for those over the age of 18 years, except if you are pregnant or breastfeeding as per advice from the Food Standards Agency. Think of CBD as any other herbal supplement you take to support your everyday wellness routine.

As long as you choose a trusted brand that is conscious and transparent about testing and can prove the contents of its CBD oil with verified lab results, you’re in good hands.

Will CBD Make Me High?

No, unlike Tetrahydrocannabinol (THC), cannabidiol (CBD) by itself produces no psychoactive or “high” effects associated with marijuana consumption.

Both compounds are active cannabinoids in the cannabis or hemp plant, however, the way they interact with the body is different so you can take CBD with ease.

Can I Give My Pet CBD?

There are many CBD brands that make products that are safe for use on animals — either topically or orally. However, we recommend that you consult your vet before giving your fury friend CBD.

What Are the Side Effects of CBD Oil?

CBD is usually well tolerated by most people when taken directly under the tongue, however CBD oil can affect everyone differently. Some reported side effects include a dry mouth, dizziness, drowsiness, and diarrhoea but these are not common.

Can I Take CBD With Other Medication?

If you are taking any medication, we recommend discussing the suitability of CBD with your healthcare professional prior to starting your CBD journey.

Will CBD Show Up on a Drug Test?

CBD is not a drug so most drug tests will not screen for CBD. However, some CBD products may contain trace amounts of THC that, while legal in the UK if under 0.2%, may show up on a drug test.

If you are concerned and you are required to take regular drug screen tests for work (for example, you’re in the military, police service, or an athlete), then hemp seed oil, which is 100% CBD and THC free is a safe alternative.

Can I Travel With CBD?

The laws around CBD differs from country to country and the only constant is that they are constantly changing. If you’re traveling outside of the UK, it’s best that you check the specific laws of your destination before packing CBD in your suitcase to be safe.

Can I Travel Within the UK With CBD?

Yes, you can travel within the UK with CBD, provided it meets the current CBD regulations and it contains less than 0.2% THC.

Is It Safe To Travel on an Airplane With CBD in The UK?

We would recommend checking the destination of the country you are traveling to. Within the UK, CBD is safe and legal if it contains less than 0.2%. You should also ensure that, if in liquid form, the bottle is under 100 ml.

If you’re looking for something quick and easy to travel with, the CBII Discovery Duo trial kit offers two travel-size 2ml bottles while our full-size CBII CBD oils have less than 0.2% THC in 10 ml bottles — well within the legal limit.

Can I Drive After Taking CBD?

As CBD itself contains no psychoactive properties, it is safe to drive after taking CBD oil, provided it contains less than 0.2% THC.

Can I Become Addicted To CBD?

According to a report by the World Health Organisation, there is no evidence to suggest that you can become dependent on or addicted to CBD.

Doctor Julie Moltke, a medical doctor specialising in sleep and stress management says “there is no scientific evidence to suggest that you build up a tolerance to CBD. You can do that more to THC but with CBD its quite common to use the same dose regularly. It doesn’t make you dependent. There’s really no risk of addiction to CBD.”


So, now you know that CBD that meets regulations is a safe and legal product to use in the UK and nothing to be concerned about. If you’re looking for a trusted brand you can enjoy with ease, shop CBII CBD products.
