If you ever take a puff and think, “Why does vaping make me cough?”, you’re not alone.
A vape cough can show up on your first hit, after switching flavors, or even after changing devices.
This guide explains why it occurs and how to resolve the issue.
Vaping can make you cough because your throat gets dry, the nicotine hits too hard, the flavor is sharp, or the vapor is thicker than you’re used to. PG-heavy liquids, strong fruit or menthol flavors, and fast inhales can also trigger irritation
What Makes Vaping Trigger a Cough?
1. Your throat gets dry
Vapor absorbs moisture from your throat.
When your throat dries out, even a small puff can feel rough and cause a cough.
PG-heavy liquids feel sharper.
VG feels softer and smoother.
This dryness and irritation are well-documented in studies like the NIH – Vaping Aerosol Exposure and Airway Response, which explains how vapor can affect the airway lining.
2. Nicotine strength hits too hard
A strong nicotine hit can create a quick burning or tight feeling.
This often leads to coughing, especially with high-strength nicotine salts.
If every inhale feels harsh, the level may simply be too strong for you.
3. Your inhale technique feels like smoking
Smoke and vapor behave differently.
If you inhale fast and deep—like a cigarette—the vapor can rush into your throat too quickly.
Slow, gentle puffs help a lot.
Warm vapor from powerful devices can also make the first inhale feel rough.
4. Some flavors are naturally harsher
Certain flavors carry stronger aromatic compounds that can irritate your throat:
- lemon
- citrus
- mango
- berry
- menthol
- icy mint
These flavors create a sharper hit and can trigger a cough more easily.
Mild mint, tea, and tobacco blends usually feel smoother.
5. A burnt or old coil
A burnt coil produces harsh, bitter vapor.
This almost always causes coughing.
If you taste anything burnt:
- stop vaping
- Replace the coil
- or switch to a new disposable
Burnt hits are one of the most common causes of coughing from vaping.
6. Your lungs are adjusting
If you’re vaping for the first time — especially if you never smoked — your lungs need time to adjust.
A tickly cough is very normal during the first few days.
7. Vapor thickness is too much
Some vapes push out dense, warm clouds.
If the vapor is too thick for your airflow, your throat can react with a cough.
Lowering power or reducing airflow usually helps.
Does Vaping Cause Mucus or Phlegm?
Yes, it can.
Dryness from vapor can make mucus feel thicker.
This can lead to:
- phlegm
- throat clearing
- a tickly cough
- sticky dryness
Research on airway response, as seen in the NCBI – Respiratory Effects of E-Cigarette Aerosol Exposure, demonstrates how vapor can irritate the throat and lungs.
How to Stop Coughing When You Vape
1. Lower the nicotine
A softer nicotine level reduces the throat hit.
2. Choose higher VG
VG feels smoother and less sharp than PG.
3. Pick gentler flavors
If fruity or icy flavors make you cough, try:
- tobacco
- light mint
- tea
- milder dessert flavors
4. Take slow, steady puffs
A gentle inhale makes vapor easier to handle.
5. Stay hydrated
Water helps reduce dryness, irritation, and mucus.
6. Replace burnt coils
A burnt taste almost always leads to coughing.
7. Use lower wattage
Cooler vapor is easier on your throat.
When a Vape Cough Needs Attention
Most coughing is mild and fades with small adjustments.
But if you keep feeling:
- strong chest tightness
- trouble breathing
- worsening cough
- sharp pain
Stop vaping and speak with a professional.
The NIDA – How Vaping Affects the Body also explains how vapor and nicotine can affect the airway, which helps you understand when symptoms may be more than simple irritation.
Why You Might Cough More When Switching From Smoking to Vaping
Even long-time smokers can cough when they switch to vaping.
Vapor is smoother, less hot, and denser than smoke, so the inhale method needs time to adjust.
Soft pulls usually make the transition easier.
