Why you cough when you start vaping, and how to stop

The moment you cough tells you a lot. A cough right at the start of the inhale points to technique or throat hit. A cough on the very first puff of a new pod points to a dry wick. A cough only on long puffs points to the coil running too hot. And a cough that is there all day, whether you vape or not, is something to talk to a professional about.

Tap the moment that matches yours and you will get the most likely cause and the fix. Change one thing at a time, so you know what worked.

Smokers are used to a short, sharp drag. Do that on a vape and you pull a dense mouthful of vapour straight to the back of your throat, which is exactly what triggers a cough. Try instead a slow, gentle draw of two to four seconds into your mouth, take the device away, then breathe in with a little extra air.

The other trap is inhaling straight to the lungs on a tight mouth-to-lung pod. That is a direct-to-lung habit on a device built for MTL, and it concentrates everything. Our guide on how to vape properly walks through the puff in detail, and it is worth a read even if you think you have it sorted.

Two things in the bottle drive throat hit: nicotine strength and PG. Freebase nicotine gets noticeably harsher as the milligrams climb, and PG carries that catch more than VG does. So an 18mg freebase in a 40/60 liquid is about as punchy as an MTL vape gets.

If you cough on most puffs, try one of these: a 50/50 instead of a high-PG liquid, a nic salt instead of freebase at the same strength, or one step down in strength. A range from our salt nicotine shelf is the usual answer for heavy smokers who need 20mg but find freebase too sharp. The ratios below run from harshest to softest.

Strength cuts both ways. Too much nicotine makes the throat hit sharp and can leave you light-headed. But too little nicotine makes you puff harder and faster to compensate, and that can cause coughing too. The aim is a strength where a few gentle puffs feel satisfying.

If you started on 20mg freebase and cough constantly, a 10mg or 20mg nic salt is often smoother at a similar level of satisfaction. If you are on 3mg in a pod and puffing hard all day, going up might actually calm the cough. Our nicotine strength guide matches strength to your smoking habit.

If you are not sure which cause is yours, work down this list in order. Each item takes a minute or less, and most people find their answer in the first three. Do not change your liquid and your strength on the same day, or you will not know which one helped.

If you have been through the whole list and still cough on most puffs after a week, give our guide to throat hit a read. It explains each lever in more depth, including the flavour ingredients, like menthol, that can make a hit feel sharper than you expected.

A tickly cough in the first few days of vaping is common and usually settles once the technique and liquid are right. A cough that hangs around is a different matter. The NHS advises seeing a GP if you have had a cough for more than three weeks, and sooner if you are coughing up blood, have chest pain or feel very unwell.

Vaping is not risk-free. The NHS says nicotine vaping is less harmful than smoking, but that does not mean you should ignore symptoms. If something does not feel right, get it looked at.
