Why Vaping Causes Sore Throat

Sore throat is a pretty common problem. There are many types of CBD pens, and some are more likely to cause throat issues than others. Thus, for example, nicotine vapes are likelier to irritate the throat. However, CBD vapes are less likely to cause throat issues. Nevertheless, it is a possibility. Hence, those who vape regularly want to understand why vaping causes sore throat.

CBD, or cannabidiol, has become a popular remedy for a wide range of ailments, from chronic pain to anxiety. As its usage continues to grow, so does the discussion surrounding its potential side effects. One of the concerns that users have raised is the occurrence of sore throat after taking CBD.

It is good to know that a sore throat rarely indicates anything severe. It may cause sporadic cough and rarely some pain or throat irritation. Understanding the cause of sore throat may help you enjoy vaping safely.

Understanding CBD and Its Effects

It is a bit paradoxical that even CBD vapes might cause sore throat. This is because CBD is generally not known to cause throat issues. Moreover, CBD may lower inflammation and help with sore throat.[1] However, it appears that vaping CBD may cause sore throat in some.

CBD is a natural compound found in the cannabis plant. Unlike its cousin, THC (tetrahydrocannabinol), CBD is non-psychoactive, making it a popular choice for those seeking the potential therapeutic benefits of cannabis without the “high.” It interacts with the endocannabinoid system in the human body, which plays a crucial role in regulating various physiological processes, including pain sensation, mood, and immune response.[2]

While CBD is generally considered safe, being aware of potential side effects is essential. Although relatively rare, one of these side effects is a sore throat.

Some reasons for sore throat could be:

Quality and Purity of the CBD Product

The quality and purity of the CBD product you’re using can significantly impact whether or not it will cause a sore throat.

Low-quality or impure CBD products may contain contaminants like pesticides, heavy metals, or solvents. These contaminants can irritate the throat when you ingest or inhale the product, leading to a sore throat.

To avoid this issue, purchasing CBD products from reputable brands that provide lab-tested, high-quality options is essential.

Look for third-party lab test results, which can confirm the purity and safety of the product. Opting for high-quality products might cost more, but it can prevent unwanted side effects, including sore throats.

Inhalation Methods

One of the most common ways to consume CBD is by inhaling it through vaping. While this method provides rapid relief, it can be harsh on the throat. Inhaling hot vapour can irritate the mucous membranes in the throat and respiratory tract, potentially leading to a sore throat.

If you prefer inhalation as your CBD consumption method, consider some best practices to minimize the risk of a sore throat:

  • Use a vaporizer with temperature control to ensure a cooler vapour.
  • Choose high-quality, clean vaping products.
  • Stay hydrated to help alleviate potential irritation.
  • Avoid overusing or inhaling too deeply during each session.

Dry Mouth and Dehydration

BD can cause dry mouth as a side effect. This condition, known as xerostomia, occurs because cannabinoids like CBD can inhibit saliva production.

A dry mouth can make your throat feel scratchy and more susceptible to irritation.

To combat dry mouth and its potential connection to a sore throat, staying hydrated is crucial. Drinking water throughout the day can help prevent dryness and soothe your throat. Additionally, chewing sugar-free gum or sucking on lozenges can stimulate saliva production and relieve dry mouth.

Allergic Reactions

Although allergy to CBD is not likely to happen, remember that any vape juice has many other organic compounds. Allergies to large organic molecules are always possible. In many cases, changing the vape brand may help, as every brand adds different kinds of additives.

Vape Intolerance

Intolerance is a bit different from allergic reactions. Some people may not tolerate vaping well. Again, this issue can be overcome in many ways. One way could be reducing CBD dosage. Others may benefit from changing flavours or even vape brands.

The Bottom Line

While CBD is generally considered safe, it’s essential to be aware of the potential side effects, including a sore throat.

A sore throat can occur due to various factors, such as the quality of the CBD product, inhalation methods, dry mouth, allergic reactions, and dosage.

To minimize the risk of a sore throat when using CBD, opt for high-quality products, choose consumption methods that suit your preferences and health, and pay attention to your dosage and tolerance.

If you experience persistent or severe throat irritation, consult with a healthcare professional to rule out any underlying issues. CBD can offer many potential benefits, and by taking precautions and using it responsibly, you can make your CBD experience more comfortable and enjoyable.
