Coughing after vaping is a common experience, especially among new users or those who have recently changed their device or e-liquid. While coughing can be a normal reaction as your body adjusts to inhaling vapour, persistent or severe coughing may indicate underlying issues with how you vape or the products you use. This article explores the reasons why vaping can cause coughing, covering physiological responses, device factors, and vaping habits.

Irritation of the Airways
One of the main reasons vaping causes coughing is irritation of the airways. Vapour contains chemicals such as propylene glycol (PG) and vegetable glycerine (VG), which can affect the throat and lungs differently. Propylene glycol is known to produce a stronger throat hit and can be drying or irritating, particularly for new users or those sensitive to it. When the throat or airways become irritated, coughing is a natural reflex to clear the irritation and protect the lungs.

Nicotine Strength and Sensitivity
High nicotine concentrations in e-liquids can also trigger coughing. Nicotine is a stimulant that can cause throat tightness and coughing, especially if the user is not accustomed to strong nicotine levels. Beginners often start with high nicotine e-liquids, which can overwhelm the throat and lungs. Reducing nicotine strength gradually allows the body to adapt and reduces coughing.

Inhalation Technique
How you inhale vapour can influence coughing. Taking deep, fast, or overly forceful puffs can overwhelm the lungs and trigger coughing fits. Vaping technique differs from smoking, and many new vapers benefit from slower, gentler inhales that allow the vapour to settle more comfortably in the throat and lungs. Experimenting with puff duration and frequency helps find a comfortable vaping rhythm that minimises coughing.

Device Settings and Airflow
Device characteristics can contribute to coughing as well. High-powered devices produce warmer vapour, which can be harsher on the throat and lead to coughing. Similarly, devices with restricted airflow can create a tighter draw, increasing throat irritation. Adjusting wattage settings or using devices with adjustable airflow can help produce cooler, smoother vapour that is less likely to cause coughing.

Allergic Reactions and Sensitivities
Some people may be sensitive or allergic to certain flavourings or additives in e-liquids. These sensitivities can cause inflammation or irritation in the respiratory tract, triggering coughing. If coughing consistently occurs with a particular flavour or brand, trying a different e-liquid with simpler ingredients or fewer additives may help.

Underlying Health Conditions
Existing respiratory conditions such as asthma, chronic bronchitis, or allergies can make individuals more prone to coughing when vaping. Vaping introduces a foreign substance into the lungs, which can exacerbate symptoms in susceptible people. Those with respiratory issues should consult healthcare professionals before vaping and monitor their reactions closely.

Conclusion
Vaping can cause coughing due to throat and airway irritation, nicotine strength, inhalation technique, device settings, and individual sensitivities. New users often experience coughing as their bodies adjust to vaping, but persistent coughing warrants attention. Adjusting nicotine levels, refining vaping technique, selecting appropriate devices and e-liquids, and considering health conditions can reduce coughing and improve the vaping experience. If coughing continues or worsens, seeking medical advice is recommended.
