Can vaping CBD oil e-liquid get you high?

CBD, or cannabidiol, is one of the naturally occurring cannabinoids found in cannabis plants. It is available in a wide range of products, including oils, capsules and liquids intended for use in refillable vaping devices.

One of the most common questions about CBD is whether vaping it can make you feel high. The straightforward answer is that CBD itself is not intoxicating in the way that THC is. However, the full answer is a little more complicated because the composition and quality of CBD products can vary.

Is Vaping CBD Oil Safe?

It is not accurate to describe vaping CBD as completely safe or non-toxic. Although CBD itself does not produce the intoxicating effects associated with THC, inhaling any substance into the lungs carries potential risks and the quality of CBD vape products can vary.

Consumers should also distinguish between products specifically formulated for vaping and ordinary CBD oils designed to be swallowed. Oils intended for oral use should not automatically be assumed to be suitable for inhalation.

CBD can also cause side effects and may interact with medicines. Anyone taking medication, pregnant or breastfeeding, or concerned about an existing health condition should seek appropriate medical advice before using CBD products.

Will Vaping CBD Get You High?

Pure CBD does not produce the characteristic high associated with cannabis. That effect is principally associated with THC, or tetrahydrocannabinol.

CBD and THC can both occur naturally in the cannabis plant, but they have very different effects. CBD itself is not controlled under the Misuse of Drugs Act 1971 when it is present as an isolated pure substance.

However, this does not mean that every product labelled as CBD is automatically THC-free. The UK Home Office notes that consumer CBD products may contain varying amounts of controlled cannabinoids, including THC. The exact composition therefore matters.

If a CBD vape liquid contains appreciable quantities of THC because of contamination, poor manufacturing or inaccurate labelling, its effects and legal status could be different from those of a properly produced CBD product.

What Is the Difference Between CBD and THC?

CBD and THC are both cannabinoids, but they interact with the body differently.

• CBD (cannabidiol) is not intoxicating and does not normally produce a cannabis-style high.
• THC (tetrahydrocannabinol) is the main cannabinoid responsible for the intoxicating effects associated with recreational cannabis.
• THC and a number of other cannabinoids are controlled drugs in the UK.
• Pure CBD itself is not a controlled drug, although CBD products containing controlled cannabinoids may be subject to UK drugs legislation.

This distinction is particularly important when considering both the legality of CBD products and the possibility of a positive cannabis drug test.

What Is CBD?

CBD stands for cannabidiol. It is one of a number of naturally occurring cannabinoids found in Cannabis sativa.

CBD can be extracted from cannabis plants and incorporated into consumer products. Depending on the manufacturing process, a CBD product may also contain other naturally occurring cannabinoids and plant compounds such as terpenes.

The composition of CBD products varies considerably. This is one reason why consumers should not assume that every product labelled “CBD” has exactly the same cannabinoid profile.

The Endocannabinoid System

The human body has an endocannabinoid system made up of naturally occurring signalling molecules, enzymes and cannabinoid receptors. It has roles in a range of physiological processes.

Researchers continue to study how cannabinoids such as CBD interact with this system and with other biological pathways. CBD’s effects are complex and it should not be assumed that taking CBD simply “restores balance” to the body.

Research into cannabinoids remains active, but evidence varies considerably depending on the particular condition, dose, formulation and method of administration being studied.

What Is CBD Used For?

Consumer CBD products are widely marketed for relaxation, sleep and general wellbeing. You may also see claims relating to anxiety, pain, inflammation and other health conditions.

It is important to distinguish consumer CBD products from licensed or prescribed cannabis-based medicines. Evidence supporting many of the health claims made for ordinary consumer CBD products remains limited or uncertain, and a CBD vape should not be regarded as a treatment for a medical condition.

There are some cannabis-based medicines available for particular conditions in the UK, but these are regulated medicines and are different from ordinary CBD products sold online or on the high street.

CBD and Medical Claims

A product can fall within medicines regulation if it is presented as treating or preventing disease or has a medicinal function. Consumers should therefore be cautious about claims that an ordinary CBD oil or vape can treat conditions such as anxiety, chronic pain, arthritis, epilepsy or depression.

If you are considering CBD because of a medical problem, speak to a doctor or pharmacist rather than relying on health claims made for an unlicensed consumer product.

Is CBD Legal in the UK?

The legal position is more complicated than the often-repeated statement that CBD is legal provided it contains less than 0.2% THC.

The 0.2% figure should not be used as a general legal limit for THC in finished CBD products. It is associated with rules surrounding the cultivation of approved industrial hemp varieties and is not a blanket permission for consumer CBD products to contain up to 0.2% THC.

Pure CBD, as an isolated substance, is not controlled under the Misuse of Drugs Act 1971. However, THC, cannabinol and various other cannabinoids are controlled substances.

The Home Office states that a CBD product containing controlled cannabinoids is itself subject to drugs legislation unless an applicable exemption or other lawful route applies.

One important exemption under the Misuse of Drugs Regulations 2001 concerns certain “exempt products”. Among other requirements, no individual component part of such a product may contain more than 1 mg of a controlled drug. The Home Office considers the relevant unit for this threshold to be the container, such as a bottle of oil, rather than an individual dose.

You can read the current Home Office guidance on cannabis, CBD and other cannabinoids for further information.

Can CBD Affect a Cannabis Drug Test?

Standard cannabis drug tests are generally designed to identify THC or its metabolites rather than CBD itself. Using pure CBD would therefore not normally be expected to produce a positive result for cannabis simply because CBD is present.

There is, however, an important qualification. Some CBD products may contain traces of THC or other cannabinoids because of their formulation, manufacturing process or inaccurate labelling.

Repeated use of a product containing THC could potentially expose someone to enough THC to become relevant to drug testing. The risk depends on factors including the actual composition of the product, frequency of use, amount used and the type and sensitivity of the drug test.

This means someone who is subject to workplace, sporting or other drug testing should not assume that every CBD product is completely free from the possibility of a cannabis-positive result.

Current UK Vaping Rules

UK vaping rules have changed since this article was first published.

Since 1 June 2025, businesses in the UK have been prohibited from selling or supplying single-use vapes. The ban applies to all single-use vapes, whether or not they contain nicotine.

Reusable vaping devices can still be sold, provided they meet the applicable requirements. To qualify as reusable under the single-use vape rules, a device must be both rechargeable and refillable, with a removable and replaceable coil where the device uses a coil.

You can read the current UK Government guidance on the single-use vape ban for more information.

Things to Consider When Buying CBD Products

If you choose to use a CBD product, its composition is particularly important. Consider whether the supplier provides clear information about what the product contains and whether cannabinoid testing has been carried out by an appropriate laboratory.

Be cautious about products that:

• promise to cure or treat a wide range of medical conditions;
• do not clearly identify their cannabinoid content;
• make vague claims about being completely THC-free without supporting information;
• are intended for swallowing rather than specifically formulated for vaping;
• come from a source that provides little information about manufacturing or testing.

For someone who may undergo drug testing, knowing what is actually present in a CBD product can be particularly important.

Can Vaping CBD Oil Get You High? The Bottom Line

CBD itself should not produce the intoxicating high associated with THC. Pure CBD is not a controlled drug in the UK, whereas THC is a controlled cannabinoid.

However, it is too simplistic to say that every CBD vape product is THC-free or incapable of causing problems. Commercial CBD products can contain other cannabinoids, and the actual composition of a product matters for its effects, legal status and potential implications for drug testing.

The old rule of thumb that a finished CBD product is automatically legal as long as it contains less than 0.2% THC is also incorrect. Current UK law is more complicated and consumers and suppliers should refer to current Home Office guidance where the controlled cannabinoid content of a product is relevant.

Finally, vaping CBD should not be presented as a proven treatment for pain, anxiety, depression or other medical conditions. Research into CBD continues, but consumer CBD products are not the same as licensed or prescribed cannabis-based medicines.
