Vaping can be an enjoyable experience for many, but it sometimes leads to an unpleasant side effect: a sore throat. This discomfort can range from a mild tickle to a painful irritation. Understanding why vaping causes a sore throat and how to address this issue can help vapers continue to enjoy their experience with fewer unpleasant side effects.

Why Vaping Causes a Sore Throat

Several factors associated with vaping can contribute to a sore throat:

  1. Dehydration: Propylene glycol (PG) and vegetable glycerin (VG), the main components of most e-liquids, are hygroscopic, meaning they absorb moisture. When you vape, these substances can draw moisture from your mouth and throat, leading to dryness and irritation.
  2. High Nicotine Levels: E-liquids with high nicotine content can be more irritating to the throat. Nicotine is a potent substance that can cause a harsh throat hit, especially in new users or when used in high concentrations.
  3. Flavorings: Some flavoring compounds used in e-liquids, particularly certain acidic flavors like citrus or cinnamon, can also irritate the throat. Each individual may react differently to various flavorings.
  4. Power Settings of the Vape Device: Using high power settings on your vaping device increases the temperature at which the e-liquid is vaporized, potentially leading to a harsher throat hit. This higher temperature can cause more irritation to the throat.
  5. Vaping Technique: Inhaling the vapor directly into the throat, rather than holding it in the mouth first, can increase throat irritation. Additionally, long and continuous vaping sessions without breaks can exacerbate throat dryness.

How to Treat and Prevent Sore Throat from Vaping

To alleviate and prevent sore throat from vaping, consider the following tips:

  1. Stay Hydrated: Drink plenty of fluids to counteract the dehydrating effects of the ingredients in e-liquids. Keeping well-hydrated helps maintain the natural moisture levels in your throat.
  2. Adjust Nicotine Strength: If you’re experiencing throat discomfort, try lowering the nicotine concentration in your e-liquid. You might find that a lower nicotine level reduces throat irritation.
  3. Choose Your Flavors Wisely: Be mindful of the flavors you choose. Some vapers find that switching to milder flavors, or those known to be less irritating like vanilla or berry, can significantly reduce throat discomfort.
  4. Modify Device Settings: Experiment with lowering the power settings on your vaping device. Lower temperatures will produce a smoother vapor that is less likely to irritate your throat.
  5. Change Your Vaping Technique: Try to inhale the vapor into your mouth first and let it cool slightly before inhaling it into your lungs. Additionally, take breaks during your vaping sessions to allow your throat to recover.
  6. Use a Humidifier: Adding moisture to the air with a humidifier, especially in dry environments or during winter months, can help relieve throat dryness.
  7. Gargle with Salt Water: Gargling with warm salt water can soothe a sore throat and reduce inflammation. This is a tried and true remedy for various causes of throat irritation.
  8. Try Over-the-Counter Remedies: Lozenges, sprays, and other throat pain relief products can provide temporary relief for sore throat symptoms.


While vaping is less harmful than smoking cigarettes, it can still cause throat irritation and soreness for some users. By understanding the contributing factors and implementing simple changes in habits and settings, most vapers can successfully reduce or eliminate throat discomfort. Always consider your body’s reactions and adjust your vaping practices accordingly to ensure a comfortable and enjoyable vaping experience.
