CBD vaping has become a popular way to try CBD due to its convenience and fast onset. Many people use CBD vape products as part of their wellness routine, but like any inhaled product, vaping CBD can sometimes come with side effects, including coughing. You can also experience vaping-related issues, such as clogging and a burnt taste, all of which can be frustrating, especially for new users.
This guide focuses on these three common issues, explaining why they occur and what you can do to improve your CBD experience. We’ll also look at other possible CBD vape effects and how product quality and device choice can make a real difference.

The most common CBD vape side effects
When people talk about CBD vape side effects, they’re usually referring to how the body responds to inhaling vapour, rather than the effects of CBD alone. CBD is generally well-tolerated, but CBD vaping introduces additional factors such as heat, aerosols, and inhalation technique, all of which can affect the throat and airways.
Commonly reported CBD vape effects and why they can occur:
| Side effect | Why can it happen with CBD vaping? |
| Throat irritation/coughing | Warm vapour, aerosols, or the inhale technique can irritate the throat and airways |
| Dry mouth | CBD can be linked with reduced saliva, and vaping can feel drying |
| Scratchy throat | Stronger CBD vape liquids plus heat can increase throat dryness/irritation |
| Light-headedness/drowsiness (if too much) | Taking too much CBD in a short time can cause drowsiness or light-headedness for some people |
Less commonly, some people report mild stomach upset (like nausea) or appetite changes when using CBD. If you’re concerned about vaping CBD, stop using the product, take a break, and consider switching to a lower strength or a different format, such as CBD oils or CBD edibles.
CBD vaping isn’t suitable for everyone, particularly if you’re:
- Pregnant or breastfeeding
- Have a respiratory condition, such as asthma
- Taking medication that could interact with CBD
If you have any medical conditions or you’re unsure what’s right for you, it’s always best to speak with a healthcare professional before vaping CBD.
Understanding vaping CBD and coughing
Now that we’ve reviewed common side effects, it’s worth taking a closer look at coughing, as it’s one of the main issues people can have with vaping CBD or using CBD vape pens or pods.
Common reasons CBD vaping can cause coughing:
- Inhalation technique: CBD vape pens are designed for slow, gentle draws. Fast or deep inhales can irritate the throat.
- Propylene glycol sensitivity: Some CBD vape juice contains propylene glycol, which may irritate sensitive airways.
- Dry airways: Vaping CBD can contribute to dry mouth or throat, increasing the urge to cough.
- High CBD concentrations: Strong CBD vape oil may feel harsh, especially for beginners.
Staying hydrated, slowing your inhale, and starting with lower-strength CBD vape oil can significantly reduce coughing.
Why CBD vape pens clog and how to prevent it
Clogging is when the airflow or oil path inside a CBD vape pen or CBD cartridge gets partially blocked, making it harder to inhale and sometimes causing poor vapour or crackling. It isn’t a health or physical side effect, but it is one of the most common frustrations with CBD vape pens.
Most likely reasons for clogging:
- Thick CBD oil: CBD vape liquid can be quite thick, so it may move more slowly through the cartridge, restricting airflow and potentially leading to clogging.
- Temperature changes: Cold environments can cause CBD e-liquid to thicken, potentially restricting airflow and leading to clogging.
- Residue buildup: Repeated heating and cooling can leave residue inside vape cartridges, gradually blocking airflow.
- Low-quality hardware: Poorly made cartridges are more prone to clogging and leaking, especially over time.
Storing devices upright at room temperature helps, and device quality matters too. Better-made CBD vape pens and cartridges tend to have more consistent airflow, tighter seals, and better internal designs, which make them less likely to clog. If clogging keeps happening, switching to a higher-quality CBD vape device can make a noticeable difference.

Potential taste issues when vaping CBD
Taste issues are often linked to the CBD extract, the quality of the CBD vape liquid, or how the device is used. Importantly, taste problems can overlap with the other main issues: a harsh or burnt flavour can trigger coughing, and thicker liquids that affect flavour can also contribute to clogging.
Common CBD vape taste problems:
- Earthy or bitter flavour: CBD vape liquid made with natural hemp extracts, especially full-spectrum CBD, can taste earthy or slightly bitter. This is often just the natural flavour profile of hemp rather than a fault.
- Burnt taste: A burnt or harsh flavour is usually caused by overheating the coil, taking repeated puffs without a pause, or vaping when the cartridge is running low. This type of taste is more likely to irritate the throat and cause coughing.
- Chemical or unpleasant aftertaste: This is commonly linked to low-quality CBD vape juice, flavourings that don’t hold up well when heated, or cartridges that aren’t well-matched to thicker CBD vape liquids. Poor cartridge performance can also increase the likelihood of clogging and inconsistent vapour.
You can reduce the likelihood of taste issues by choosing well-formulated CBD vape products, avoiding excessive heat, allowing a short pause between puffs, and replacing cartridges or coils when the flavour starts to drop off to help maintain a smoother taste.
What does vaping CBD do to your lungs?
When you’re vaping CBD, you inhale a fine mist (an aerosol) made by heating CBD vape liquid, so the effects of vaping can feel more noticeable than taking CBD oil or edibles. As aerosol particles go straight into the airways, some people notice throat or airway irritation, especially with higher-strength CBD e-liquids or deep inhales.
To understand what that aerosol might do, scientists sometimes compare CBD or nicotine aerosols in lab studies, including CBD and nicotine aerosols and vaporised CBD versus nicotine. Some experimental research has found that CBD aerosols can trigger stronger irritation and inflammation markers than nicotine aerosols, but these are short-term lab setups and don’t directly tell us what happens with everyday use over the years. Long-term human research on CBD vaping is still limited, so there isn’t a clear, definitive answer yet – repeated inhalation of any aerosol may not be risk-free.
It’s also important to separate regulated products from unregulated ones: public health investigations into vaping-related lung injury and severe lung damage have been most strongly linked to unregulated or contaminated vape products, where additives such as vitamin E acetate were found – not compliant CBD vape products.
The importance of CBD e-liquid quality
The quality of your CBD vape liquid plays a major role in how smooth vaping feels, how it tastes, and how well your device performs. Poor-quality liquids are more likely to cause harsh vapour, burnt flavours, and even clogging, which can increase irritation and coughing.
High-quality CBD vape products typically offer:
- Clear ingredient lists, so you know exactly what you’re inhaling
- Simple formulations without unnecessary thinning agents or flavour additives
- Third-party lab testing (COAs) to confirm purity, CBD content, and safety
CBD vape liquids can be made using CBD isolate, broad-spectrum CBD, or full-spectrum CBD, and each can influence flavour, smoothness, and overall vaping comfort. Choosing a well-formulated liquid suited to vaping can help reduce common CBD vape side effects and improve consistency.
Essentially, always check the quality of the vape liquid you’re buying, read the ingredient list, and choose trusted retailers with lab test results for peace of mind.
Choosing the right device for CBD vaping
CBD vape liquids are typically thicker than standard e-liquids, so CBD vape devices need to handle lower heat levels and smoother airflow.
Refillable and pod-based devices designed specifically for CBD tend to offer:
- Lower, controlled power output, reducing harsh vapour
- Cartridges or pods suited to thicker CBD vape liquid
- Smoother airflow, which can help reduce coughing
If you’re vaping CBD, you should use a device designed for CBD vaping. Devices built mainly for vaping nicotine often prioritise stronger vapour and faster heating, which can overwhelm CBD vape liquid and make taste issues, burnt flavour, and clogging more likely. A CBD vape device (or CBD pod system) designed for thicker CBD vape oil and lower heat helps keep the vapour smoother and more consistent.
When selecting a device, look for trusted brands and retailers offering clear product information and compatibility with CBD vape liquid. Please note that disposable CBD vape pens are banned in the UK, so you’ll need a reusable device.
How to try to reduce CBD vape side effects
Most CBD vape side effects and issues linked to CBD vaping can be minimised with a few simple adjustments:
- Choose lab-tested, well-formulated CBD vape oil
- Start with lower CBD strengths
- Take slow, gentle inhales
- Stay hydrated
- Store and clean vape cartridges properly
Listening to your body is an important part of responsible CBD use, and if vaping doesn’t suit you, alternative CBD products may be worth exploring, including CBD oils, CBD edibles, and CBD hemp flowers.
Summary
CBD vape side effects, such as coughing, clogging, and taste issues, are relatively common and are usually linked to inhalation technique, device design, or CBD vape liquid quality rather than CBD itself. Vaping introduces heat and aerosols, which can irritate the throat and airways for some people, especially with higher-strength CBD e-liquids or unsuitable devices.
Choosing well-formulated, lab-tested CBD vape products and using devices designed specifically for CBD can help reduce these issues. Paying attention to technique, strength, and product quality allows many people to improve their CBD vaping experience or decide whether a non-inhaled CBD format is a better fit.
