What to know about vaping CBD
With its legalization in many countries around the world, many people have started to use cannabidiol (CBD) products for its potential medical benefits. CBD users ingest the compound in various ways, including vaping.
Some studies suggest that CBD may help treat some chronic conditions, such as anxiety and pain. However, most studies have evaluated the effects of taking CBD orally and not through inhalation.
The Centers for Disease Control and Prevention (CDC) recommend against vaping, as the long-term effects are still unknown.
Keep reading to learn more about vaping CBD and its potential therapeutic uses, as well as information about certain vape pens, formulations, and the risks involved.
Is CBD legal? Hemp-derived CBD products with less than 0.3% THC are legal federally but still illegal under some state laws. Cannabis-derived CBD products, on the other hand, are illegal federally but legal under some state laws. Check local legislation, especially when traveling. Also, keep in mind that the Food and Drug Administration (FDA) have not approved nonprescription CBD products, which may be inaccurately labeled.

Cannabidiol (CBD) is a compound derived from cannabis. Unlike tetrahydrocannabinol (THC), CBD does not produce a high. People use CBD in a wide variety of ways for its potential therapeutic effects, which may include:
- pain relief
- seizure and epilepsy treatment
CBD may also have antioxidant properties and may be toxic to some cells. Researchers are currently investigating the use of CBD in several disease states, including:
- neurodegenerative diseases
- anxiety disorder
- childhood diseases, such as tuberous sclerosis complex that has a prevalence lower than 5 in 10,000 individuals
Approved uses and studies
Recently, the Food and Drug Administration (FDA) approved the use of Epidiolex, a CBD oral solution, indicated for use in Lennox-Gastaut or Dravet syndrome, which are rare forms of epilepsy.
In Canada and Europe, doctors can prescribe Sativex, which is a mouth spray that contains both CBD and THC to treat spasticity in multiple sclerosis.
According to the United States National Library of Medicine, there are currently 228 studies on CBD that are completed, active, or pending results.
People may also find CBD in commercial products, such as health and food supplements.
One of the challenges that consumers and doctors face is the lack of standardized dosing and an understanding of what dose is therapeutic. Today, dosing recommendations for CBD are still unclear.
The challenge is extended further with the different routes of administration. People consume edibles, vape, and apply topical CBD to their skin.

Many people are now using e-cigarettes as a device for marijuana-based products, including CBD.
Studies on vaping CBD oil are lacking. Most clinical trials around CBD have focussed on oral capsules, sublingual sprays, or oral solutions.
People living with asthma and chronic obstructive pulmonary disease often use aerosolized therapies. This delivery system supplies the medication directly into the lungs, which results in a rapid clinical effect. Generally, people also need smaller doses compared with oral or subcutaneous injections.
The features of condensation aerosols can make vaping seem like a more effective method of taking CBD. However, since vaping is still a relatively new practice, researchers are unclear about its benefits and risks and need to conduct further investigations.
In the United States, CBD extracted from the plant Cannabis sativa is still a Schedule I drug as the FDA have not approved its use for medicinal uses.
Also, the FDA do not regulate the manufacturing and labeling of CBD oil products in the U.S.
The condensation aerosols in vape pens can be useful delivery systems for drugs. However, an article in the Frontiers of Pharmacology warns that people must be aware that not all products contain the amount of CBD that the label suggests.
In one study, researchers analyzed two e-liquids, Cloud 9 Hemp Yellow Brick Road and Easy Rider. According to the label, each product consisted of 3.3 milligrams per milliliter (mg/mL) of CBD. However, researchers noted that Cloud 9 Hemp Yellow Brick Road had 7.6 mg/mL of CBD, and Easy Rider had 6.5 mg/mL. These deviations illustrate the consequences of a lack of regulation.
Without quality control, people have exposure to unknown doses of CBD, as well as other components that may carry risks.
According to an article in the International Journal of Environmental Research and Public Health, the oil may contain lower levels of CBD than the label lists.
This might occur because some oils may have been in storage for long periods under conditions that promote its instability. This can account for lower concentrations in the final purchased product.
Recently, doctors have reported several cases of severe lung injury in people who vape. According to a report from the CDC, as of February 2020, 2,807 people in the United States have received hospital treatment for e-cigarette, or vaping, product use-associated lung injury (EVALI). Of those people, 68 died.
The CDC recommends that people who wish to vape should:
- not use THC-containing e-cigarettes or vaping products from unreliable sources
- not use e-cigarettes or vaping products that contain vitamin E acetate
- not add additional ingredients to a vaping product
Vaping products and e-cigarettes are also not safe for youth, young adults, or anyone who is pregnant.
When selecting pens and formulations for vaping CBD, people should buy from reliable sources. All manufacturers make their products differently, and they lack the rigorous quality control that FDA-approved products undergo.
There are many pens and formulations available for purchase. Choosing an appropriate one is a challenging task, as there is a lack of evidence to support the use of vaping CBD for medicinal purposes.
