Cough – Why Vaping Makes You Cough & How to Stop It

Definition

In vaping, a Cough is the involuntary expulsion of air from the lungs that many new and even some experienced vapers experience after inhaling vapour. It is not a feature or component of a device but rather a common physiological reaction caused by the higher temperature, different pH, or increased density of vapour compared to ambient air. While the sensation can be alarming, it is usually harmless and diminishes as the user adapts to vaping technique or adjusts their setup. Some vapers deliberately trigger a light cough, believing it intensifies nicotine absorption, though this practice is debated.

Technical Details

The cough reflex is initiated when Coil-generated aerosol irritates the cilia lining the upper airway. Key variables include:

  • Power (watts): Higher wattage produces hotter vapour, increasing irritation.
  • PG/VG ratio: Propylene glycol (PG) carries flavour well but is more irritating than vegetable glycerin (VG); high-PG liquids often provoke more coughing.
  • Airflow: Restricted airflow raises vapour density and temperature, making a Hit“>harsh hit more likely.
  • Nicotine strength & type: Free-base nicotine at ≥12 mg mL-1 or high-strength salts can trigger a throat spasm, especially in Cloud Chasing setups.
  • Coil material & build: A freshly installed Clapton Coil with un-wicked cotton can emit metallic or burnt particles, causing an immediate cough.

Variations range from a single dry throat tickle to a sustained hacking fit. Some advanced users monitor “cough latency” (time from inhale to cough) as an informal gauge of wicking efficiency or nicotine uptake.

Usage & Tips

  • For beginners: Start with low-nicotine, high-VG e-liquid and open airflow. Take slow, mouth-to-lung (MTL) draws before progressing to direct-lung (DL) inhales.
  • Troubleshoot harsh hits: If the cough persists, check that the Cartridge or tank is adequately filled and the Cotton is fully saturated; dry hits are the fastest route to a painful cough.
  • Stay hydrated: PG and VG are hygroscopic; drinking water between puffs reduces throat irritation.
  • Safety note: Chronic or worsening cough after weeks of vaping may indicate sensitivity or an underlying respiratory issue—consult a healthcare professional.

History & Context

Early cig-a-like devices (c. 2008) produced minimal vapour and rarely triggered coughing. With the rise of sub-ohm tanks and high-wattage mods around 2013–2015, the prevalence of coughing increased as users chased bigger clouds. Today, manufacturers fine-tune airflow, coil geometry, and nicotine salt formulations specifically to reduce the “cough factor,” making vaping more approachable for smokers looking to switch.
