Why Do Vapes Make Me Cough? The Complete Guide to Fixing Your Cough Today

You take a puff. You cough. Your friend takes a puff. Nothing happens.

You start to worry. Is something wrong with you? Is vaping bad for you? Should you stop?

Here's the truth: Nothing is wrong with you. And you don't need to stop.

Most people who cough when vaping aren't broken; they're just using the wrong settings. The good news? This is fixable in minutes. Not days. Not weeks. Minutes.

I've spent over 10 years helping vapers solve problems just like this. And I can tell you with complete confidence: 95% of cough problems come from one of 5 specific causes. And every single one is easy to fix.

By the end of this guide, you'll know exactly why you're coughing. You'll know what to change. And you'll stop coughing before your next vaping session.

Why Does Coughing Happen When You Vape?

First, let's understand what's actually happening when you cough.

Your throat has a protective reflex. When something irritates it, your body says "no thanks" and makes you cough. It's the same reflex that makes you cough from pepper spray, or dust, or really cold air.

Coughing isn't dangerous. It's your body's way of protecting itself.

When you vape, the vapour goes into your throat. If something in that vapour irritates your throat, you cough. Simple as that.

The irritation can come from:

• Nicotine strength
• The type of liquid (PG vs VG ratio)
• How hot the vapour is
• How much vapour you're inhaling
• Your airflow settings

Here's what's important: None of these are problems with vaping itself. They're just settings that need adjusting.

Why Do Some People Cough and Others Don't?

Your friend takes a puff of the same device and doesn't cough. Why?

Usually because:

• Their throat is used to it (they've been vaping longer)
• They're using different settings (lower nicotine, higher VG, better airflow)
• Their device is set up for them (not for someone else)

If you're new to vaping, expect to cough for the first few days. That's normal. Your throat is adjusting to something completely new.

Cough vs Sore Throat: They're Different Problems

Before we go further, I need to mention something important.

Cough and sore throat are NOT the same thing.

A cough happens right when you vape. It's a reflex. You take a puff, your throat gets irritated, you cough for 10 seconds, then it stops. A sore throat is different. It's a lingering pain that gets worse over hours. It might feel raw or painful even when you're not vaping.

These are completely different problems with completely different solutions.

If you have a sore throat from vaping, that's a different issue. For a complete guide on that, read our full article: Can Vaping Cause Sore Throat. But if you're here for coughing right after a puff, keep reading. This guide is for you.

The 5 Causes of Vape Cough (Ranked by How Common They Are)

Now let's find out why YOU are coughing.

I'm going to explain the 5 most common causes. For each one, I'll tell you:

• What's happening
• How to know if this is YOUR problem
• Why it causes coughing
• How to fix it right now

Let's go through them.

Cause #1: Your Nicotine Strength Is Too High (60% of Cases)

This is the most common reason people cough.

What's happening: You're using nicotine that's too strong for your body. The nicotine hits your throat hard. Your throat gets irritated. You cough.

Think of it like this. If someone sprays a strong pepper into the air, everyone coughs. But if they spray a tiny bit of pepper, most people don't. The amount matters.

Nicotine is the same way.

How to Know If This Is Your Problem

Ask yourself:

• Did you just buy new liquid with a higher nicotine strength?
• Are you using a nicotine salt (25mg or 50mg)?
• Does the cough happen immediately when you inhale?
• Does the cough feel like a sharp throat hit?

If you answered yes to any of these, this is likely your problem.

Why High Nicotine Causes Coughing

Nicotine creates a "throat hit." That's the feeling you get in your throat when you vape. It's similar to smoking a cigarette.

High nicotine = strong throat hit = irritation = cough.

Different nicotine strengths hit differently:

High strength (25mg+): This causes a cough in most people. Unless you've been vaping for years, this is probably too much.

Medium strength (12-18mg): This is the sweet spot for most vapers. It gives you the nicotine you want without too much irritation.

Low strength (3-6mg): This is smooth and easy on the throat. You might not get much throat hit, but you won't cough.

How to Fix It Right Now

• Step 1: Get e-liquid with lower nicotine strength. If you're using 25mg, try 18mg. If you're using 18mg, try 12mg. If you're using 12mg, try 6mg.
• Step 2: Fill your tank with the new liquid.
• Step 3: Take a normal puff and wait 5 seconds.

Did the cough stop? Then this was your problem. Great. You're done.

A Money-Saving Tip

Many vapers think they need to buy an expensive new device to stop coughing. They don't.

Just drop your nicotine strength down by one level. See if the cough stops. You might save yourself £30-50 on a new device.

That's it. One change. Cough usually stops.

Cause #2: Your PG/VG Ratio Is Wrong (20% of Cases)

Every e-liquid is made from two ingredients: PG and VG.

PG (Propylene Glycol) = Thinner liquid, stronger throat hit, more flavour VG (Vegetable Glycerin) = Thicker liquid, smoother throat hit, bigger clouds

The ratio between these two matters. A lot.

How to Know If This Is Your Problem

Ask yourself:

• Did you switch to a new e-liquid brand recently?
• Is your liquid very thin (runny)?
• Does it feel harsh in your throat?
• Is it a high-PG liquid (70% PG or more)?

If you're using high-PG liquid, this might be your problem.

Why PG/VG Ratio Affects Coughing

High PG liquid is thin and harsh. It creates a strong throat hit. For new vapers or people with sensitive throats, this can be too much.

Think of it like this:

• High PG (70% PG / 30% VG): This is harsh. Most people find this irritating. If you're coughing, this is likely part of the problem.
• Balanced (50% PG / 50% VG): This is smooth and balanced. Most vapers prefer this. It's the best place to start if you don't know what you like.
• High VG (30% PG / 70% VG): This is the smoothest option. If you cough easily, try this. You'll get more clouds and less irritation.

How to Fix It

• Step 1: Buy e-liquid with a higher VG ratio. If you're using 70/30 PG/VG, try 50/50. If you're using 50/50, try 70/30 VG (which is 30/70 PG/VG).
• Step 2: Fill your tank and take a test puff.

Did the cough improve? Then your PG/VG ratio was the problem.

Pro Tip: If you're looking to switch liquids, always check the label. It should say "50/50" or "70VG/30PG" or something similar. If it doesn't say, ask the shop before you buy.

Cause #3: Your Wattage Is Too High (10% of Cases)

Every coil in your device has a recommended wattage range.

If you're using too high a wattage, your coil heats up too much. The vapour becomes too hot. Your throat gets irritated. You cough.

How to Know If This Is Your Problem

Ask yourself:

• Did you recently increase your wattage?
• Are you vaping at the high end of your coil's recommended range?
• Does the vapour feel hot in your throat?
• Does the cough come with a burnt taste?

If you answered yes, this might be your problem.

Why High Wattage Causes Coughing

A coil is like a tiny heater. The higher the wattage, the hotter it gets. Hot vapour irritates your throat more than cool vapour.

Different types of coils burn at different temperatures:

• Ceramic coils: These burn at 80W and above 
• Cotton coils: These burn at 60W and above 
• Mesh coils: These can handle higher temperatures, but still have limits

Your coil's recommended wattage is printed on the coil itself. Look at the side of your coil. You'll see something like "40-60W" or "50-80W."

How to Fix It

• Step 1: Find your coil's recommended wattage. It's printed on the coil.
• Step 2: Set your device to the LOWEST end of that range. If the coil says "40-60W," set your device to 40W. If it says "50-80W," set it to 50W.
• Step 3: Take a test puff. Wait 5 seconds. Does the cough improve? Then your wattage was too high. Problem solved.
• Step 4 (Optional): Once you've tested at the low setting, you can slowly increase your wattage by 5W at a time. Find the point where the vapour is hot enough for you but not so hot that you cough.

Cause #4: Your Airflow Is Too Tight (5% of Cases)

Airflow is how much air can flow through your device when you inhale.

Tight airflow = concentrated vapour = more irritation = cough.

Open airflow = less concentrated vapour = smoother vape = less cough.

How to Know If This Is Your Problem

Ask yourself:

• Do you have your airflow vents completely closed or nearly closed?
• Does it feel hard to pull on your device?
• Is the vapour very concentrated and intense?

If you answered yes, this is your problem.

Why Tight Airflow Causes Coughing

When your airflow is tight, all the vapour is concentrated. It's like the difference between a light breeze and a blast of wind. A light breeze is pleasant. A blast of wind is intense and can be uncomfortable.

Concentrated vapour is the same. It's too intense for your throat.

How to Fix It

• Step 1: Open your airflow completely. Look at the side of your device. You'll see small holes or a sliding ring. Open them all the way up.
• Step 2: Take a normal puff. Does it feel better? Does the cough stop? Then your airflow was too tight.
• Step 3 (Optional): Once you've tested with full airflow, you can slowly tighten it back up until you find the sweet spot. Maybe full airflow is too airy for you. That's fine. Just find the point where you don't cough.

Cause #5: You're New to Vaping (5% of Cases)

If you started vaping less than a week ago, this might be your problem.

Your throat isn't used to vaping yet. Even if everything is set correctly, your body might cough because it's a new sensation.

Why New Vapers Cough

If you're a former smoker, your throat is used to cigarette smoke. Vaping is different. It's a different temperature, a different sensation, a different chemical.

Your body's reaction is normal. It's not dangerous. Your throat just needs time to adjust.

How Long Does It Take?

Usually 3-5 days. By day 5 or 6, your throat has adjusted. The coughing usually stops.

What Should You Do?

• Step 1: Keep vaping. Don't panic. This is normal.
• Step 2: Give it 5 days. Your throat will adjust.
• Step 3: If you want to speed things up, lower your nicotine strength (tip #1 above). This helps your throat adjust faster.
• Step 4: After 5 days, if the coughing has improved, you just need time.

Important: If you're still coughing heavily after 7 days, you probably have one of the other 4 causes above. Go back and check them.

Use This Decision Tree to Find YOUR Cause

Now you know all 5 causes. Let's figure out which one is yours.

Answer these questions:

• Question 1: Did you just increase your nicotine strength, or are you using 25mg+ nicotine salts? → YES = Cause #1 (Nicotine too high)
• Question 2: Did you recently switch to a new e-liquid brand? Is it high-PG (70% or more)? → YES = Cause #2 (Wrong PG/VG ratio)
• Question 3: Did you increase your wattage recently? Are you at the high end of your coil's recommended range? → YES = Cause #3 (Wattage too high)
• Question 4: Is your airflow vents closed or nearly closed? → YES = Cause #4 (Airflow too tight)
• Question 5: Have you been vaping for less than 5 days? → YES = Cause #5 (You're new to vaping)

Found your cause? Great. Now let's fix it.

What to Do Right Now If You're Coughing

You're coughing right now. You need relief. Here's what to do:

Immediate Steps (Do These Now)

1. Drink water: Hydration helps calm your throat. Drink a glass of water now.
2. Breathe slowly: Don't panic. Slow, deep breaths help. In through your nose, out through your mouth.
3. Stop vaping for 10 minutes: Give your throat time to calm down. Take a break.
4. Open your airflow fully: If you have vents or airflow controls, open them all the way. This reduces the concentration of vapour.
5. Take smaller puffs next time: Use less vapour. Smaller puffs = less irritation.

What NOT to Do

1. Don't chain vape. Don't vape multiple times in a row. This makes it worse.
2. Don't use hot liquids or hot drinks. This adds irritation.
3. Don't panic. This is not dangerous. It's just irritation.

How to Fix Your Cough (The Right Way)

Now that you know your cause, here's how to fix it properly.

If It's Cause #1: Nicotine Too High

The Fix:

1. Buy e-liquid with one level lower nicotine
2. Fill your tank
3. Vape normally
4. The cough should stop within 1-2 sessions

What this means:

• 50mg nicotine salts → Try 35mg
• 25mg nicotine salts → Try 18mg
• 18mg freebase → Try 12mg
• 12mg freebase → Try 6mg

Money-Saving Tip: Lower-nicotine liquid is cheaper. You'll save money AND stop coughing. Win-win.

If It's Cause #2: Wrong PG/VG Ratio

The Fix:

1. Buy liquid with higher VG (50/50 at minimum, 70VG if possible)
2. Fill your tank
3. Vape normally
4. The cough should improve within 1-2 sessions

What this means:

• 70PG/30VG liquid → Try 50/50
• 50/50 liquid → Try 70VG/30PG (high VG)
• High VG gives you more clouds and a smoother vape

Pro Tip: If you're buying new liquid and don't know what ratio to choose, go with 50/50. It's the safe middle ground.

If It's Cause #3: Wattage Too High

The Fix:

• Check your coil's recommended wattage (printed on the coil)
• Set your device to the lowest end of that range
• Vape normally
• The cough should stop within 1-2 sessions

Example:

• Coil says "40-60W" → Set to 40W
• Coil says "50-80W" → Set to 50W
• Coil says "60-100W" → Set to 60W

What happens next: After 1-2 sessions at the low setting, you can increase by 5W at a time. Keep going until you find the perfect temperature for you.

If It's Cause #4: Airflow Too Tight

The Fix:

• Open your airflow vents completely
• Vape normally
• The cough should stop immediately

Finding your sweet spot: Once you've tested with full airflow, slowly tighten your airflow until you find a comfortable balance. Maybe full airflow feels too airy. That's OK. Just find YOUR sweet spot.

If It's Cause #5: You're New to Vaping

The Fix:

1. Keep vaping
2. Give your throat 5 days to adjust
3. Lower your nicotine strength to speed things up (optional)
4. By day 5-7, the coughing should improve

Important: If the coughing is getting worse, not better, then you probably have one of the other causes too. Go back and check them.

Prevention: Stop Coughing Before It Starts

The best fix is preventing the problem before it happens.

Daily Checklist

Before you vape, do these 3 quick checks:

• Check #1: Nicotine Strength Make sure you're using the nicotine strength you think you're using. Don't assume. Check the bottle.
• Check #2: Airflow Make sure your airflow is where you like it. Sometimes it gets bumped and changes.
• Check #3: Test Puff Take one small puff. Does it feel right? Does it taste good? If yes, vape normally.

This takes 30 seconds and prevents 90% of cough problems.

Weekly Checklist

• Check #1: Clean Your Coil Area Remove your tank. Look at the connection points. Wipe them clean with a dry cloth. Residue buildup can irritate your throat.
• Check #2: Verify Your Wattage Check that your wattage setting hasn't changed. Sometimes it resets.
• Check #3: Check Your Liquid Level Make sure your tank isn't too low. Sometimes low liquid affects the vape.

When You Buy New Liquid

• Step 1: Check the nicotine strength before you buy. Read the label.
• Step 2: Check the PG/VG ratio. It should say on the bottle.
• Step 3: When you get home, fill a small amount in your tank (about 1/4 full).
• Step 4: Take one puff and wait 10 seconds. Does it feel right?
• Step 5: If it feels good, fill your tank fully. If it feels harsh, you've found a problem to fix.

Monthly Deep Clean

Once a month, do a proper clean:

1. Remove your tank completely
2. Soak the tank in warm (not hot) distilled water for 15 minutes
3. Gently scrub with a soft cloth
4. Blow out the water
5. Let it air dry completely before refilling

This prevents clogs and keeps everything working properly.

How to Tell If Your Cough Needs Medical Attention

Most vape coughing is harmless. But sometimes, a cough is worth checking out.

Normal Cough Symptoms (No Doctor Needed)

• Cough comes and goes with vaping
• Stops after 10 minutes when you're not vaping
• No other symptoms
• Improves when you change settings
• Not getting worse

Cough That Needs Attention (See a Doctor)

• Persistent cough lasting 2+ weeks even after fixes
• Coughing up blood
• Severe chest pain when coughing
• Difficulty breathing (not just throat irritation)
• Cough is getting worse, not better

What to do: Stop vaping temporarily. See your doctor. Tell them what you've been doing.

Important: Severe symptoms are rare. But if you have them, get checked out.

What If Nothing Works? (Rare, But Possible)

You've tried everything. You've changed your nicotine. You've changed your liquid. You've adjusted your wattage. Nothing is working.

This is rare. But it happens.

What Might Be Happening

Sometimes the problem isn't one of the 5 causes above. Sometimes it's:

• A sensitivity to nicotine (some people react strongly)
• A sensitivity to PG (some people are allergic)
• An existing throat condition (not caused by vaping)
• The device itself (rarely a problem)

What to Do

• Step 1: Stop vaping for 3-5 days. See if your throat feels better.
• Step 2: See a doctor if your cough continues. Tell them you've been vaping and describe your symptoms.
• Step 3: Try a completely different setup. Borrow a friend's device. Try their liquid. See if you still cough.
• Step 4: If a different device doesn't help, the problem might not be vaping. See a doctor.

Your Next Step: Pick ONE Change and Test It

You now know the 5 causes of vape cough. You know how to identify your cause. You know exactly how to fix it.

Here's what to do next:

• Step 1: Use the Decision Tree above to find YOUR cause.
• Step 2: Make ONE change (not everything at once).
• Step 3: Vape normally for 1-2 sessions.
• Step 4: Did the cough improve?

1. YES = You found the cause. Done.
2. NO = Try the next cause on the list.

Questions People Ask About Vape Cough

1. If I cough when vaping, does that mean it's bad for me?

No. Coughing is a reflex, not a warning sign. It's the same reason some people cough from pepper spray; it's protective, not harmful. Fix the irritant (nicotine, PG, heat, airflow), and the cough stops.

2. How long until my cough stops?

If it's a settings issue (nicotine, wattage, airflow, PG/VG), then 1-2 vaping sessions after you make the change. If you're new to vaping, 3-5 days of adjustment.

3. Is coughing worse with cheap vapes?

Not necessarily. Quality matters for flavour and how long it lasts. But coughing is usually about your liquid or settings, not the device itself.

4. Should I use high VG liquid to stop coughing?

Usually yes. High VG (70%+) is smoother and usually stops coughing. But first try lowering your nicotine, that's the #1 cause. One fix at a time.

5. Can I cough from a device that's too old?

Unlikely. Old devices work the same way. If you've always coughed with it, the problem is probably your nicotine, liquid, or settings, not the age of the device.

6. Does a cough mean my coil is burnt?

No. A burnt coil tastes like ash or charcoal. Cough is usually nicotine, heat, or PG irritation. They're different problems.
