Many people who start vaping report experiencing throat irritation and coughing, especially in the first few days of use
This phenomenon can be annoying and discouraging, causing some to wonder if the e-cigarette is really a better choice compared to traditional cigarettes.
In this article, we will explore the causes of coughing related to vaping, the factors that contribute to this phenomenon, and how to minimize discomfort.
Main Causes of Coughing from E-Cigarettes
The cough resulting from e-cigarette use can be attributed to several factors, which vary from person to person. Some individuals experience this reaction only at the beginning, while others continue to have difficulties even after prolonged use. Understanding the main causes can help identify the best solutions to avoid throat irritation.
One of the main reasons for coughing when starting to vape is the body’s adjustment to new stimuli. Those who have smoked traditional cigarettes for years are accustomed to the combustion of tobacco and inhaling smoke, which impacts the throat differently from the vapor produced by e-cigarettes. Switching to a new method of inhalation can therefore provoke an irritative response, which manifests as coughing.
Another determining factor is the composition of e-liquid. Most e-liquids contain propylene glycol (PG), vegetable glycerin (VG), nicotine, and flavorings. Propylene glycol is known for its ability to carry flavors well and create a “throat hit” effect similar to traditional cigarettes. However, for some individuals, PG can be irritating, causing dryness in the mucous membranes and coughing. Those particularly sensitive to this substance may experience more intense and persistent discomfort.

The nicotine content in the liquid also plays a crucial role. A high concentration of nicotine can intensify the feeling of irritation in the throat, making coughing more likely. This is especially true for new users who choose a nicotine level that is too high for their needs. Nicotine stimulates the receptors in the throat and can trigger a defense response in the body in the form of coughing.
Another element to consider is the inhalation technique used. Traditional cigarettes are usually inhaled more quickly and with shorter puffs than electronic cigarettes. Vaping requires a slower and more controlled inhalation, which allows the vapor to be absorbed more effectively without irritating the throat. Those accustomed to smoking cigarettes may unintentionally maintain the same inhalation style, making the experience less comfortable and increasing the risk of coughing.
The Role of Body Adaptation
When starting to vape, the body goes through an adaptation period. The lungs and airways need to get used to the vapor, which has a different density and temperature compared to cigarette smoke. This process can take several days or weeks, during which it is normal to experience bouts of coughing. In many cases, the coughing gradually decreases as the body adapts to the change.
Furthermore, people who switch from smoking to vaping may already have pre-existing respiratory irritation due to prolonged tobacco use. Cigarette smoke contains numerous toxic substances and tar, which damage lung tissue and the throat. When someone quits smoking, the body begins a cleaning and regeneration process, which may temporarily increase mucus production and throat sensitivity, leading to coughing.
Some ex-smokers may also experience excessive dryness in the mouth and throat, as the propylene glycol in e-liquids tends to absorb moisture. This phenomenon can be alleviated by drinking more water throughout the day and choosing liquids with a higher percentage of vegetable glycerin, which has a gentler effect on the mucous membranes.
How to Reduce Coughing When Vaping
If coughing persists and makes it difficult to enjoy the vaping experience, there are several strategies to reduce discomfort. One of the first things to do is to check the composition of the e-liquid being used. Choosing liquids with a higher percentage of vegetable glycerin can help reduce irritation, as this substance produces a smoother vapor that is less aggressive on the throat. Alternatively, trying liquids with a lower nicotine content can help lessen the throat hit.
Another useful adjustment is to modify the inhalation technique. Instead of inhaling quickly like with a traditional cigarette, it’s advisable to take slower and deeper puffs, allowing the vapor to cool slightly before reaching the throat. This method reduces the chance of irritation and makes it easier to get used to the new inhaling style.

If coughing persists, trying different types of atomizers and coils can be helpful. Some devices produce warmer or denser vapor, which may be more irritating for those with high sensitivity. Using an e-cig with lower wattage and a higher resistance can help make the experience less intense and more comfortable.
Finally, it’s important to stay hydrated. Drinking water frequently helps keep the mucous membranes hydrated and reduces the risk of dryness and irritation. Consuming herbal teas or sugar-free drinks can also provide additional support to soothe any throat discomfort.
Conclusion
Coughing associated with e-cigarette use is a common phenomenon, but in most cases, it is temporary and can be managed with a few adjustments. The main causes include the body’s adaptation to vapor, the composition of the e-liquids for e-cigarettes, nicotine levels, and the inhalation technique. Identifying the specific reason for the cough is crucial in finding the most suitable solution. Reducing the percentage of propylene glycol, lowering the nicotine level, changing the inhalation technique, and maintaining proper hydration are effective strategies to improve the vaping experience. Over time, the body will adapt to the new method of nicotine intake, and the cough will tend to disappear, making vaping a more comfortable alternative to traditional smoking.
