Why does vaping make me feel sick?
Feeling sick after vaping is common, though there is usually a clear reason. The most likely cause is taking in too much nicotine, since it is a stimulant that can cause nausea, dizziness and a headache when you have more than your body is used to. It usually settles once you take a break.
It helps to know this is your body asking you to slow down rather than a sign of anything serious in most cases. A few simple changes usually sort it out. This page runs through the common causes, how to settle the feeling and when it is worth getting checked.
Let us look at the causes, how to settle it and when to seek advice.
The good news is that this is usually one of the more straightforward vaping problems to solve. Once you know that nicotine is the most common culprit, the fixes follow naturally, so most people settle into a strength and a pace that suit them without much trouble.
The common causes
Several things can leave you feeling queasy. Too much nicotine is the usual cause, though vaping on an empty stomach, chain vaping without breaks, dehydration and a strength too high for you can all play a part, especially when you are new or have just gone up in strength.
- Too much nicotine: the stimulant effect can cause nausea and dizziness.
- Empty stomach: nicotine on an empty stomach is more likely to upset it.
- Chain vaping: hit after hit builds up nicotine quickly.
- Dehydration: the base liquids are drying, which can add to feeling unwell.
Nicotine is the thread through most of these. It raises your heart rate and releases adrenaline for a short buzz, so having more than you are used to tips that pleasant feeling over into nausea and lightheadedness, which is the most common reason people feel sick.
This is also why people who switch from cigarettes sometimes feel it. A vape can deliver nicotine in a different pattern from smoking, so it is easy to take in more than you mean to, particularly with a higher strength liquid or by puffing more often than you used to smoke.

How to settle it
The feeling usually passes quickly with a few steps. Stop vaping for a while, drink some water, have a light snack and rest in fresh air, then the queasiness from too much nicotine tends to ease within twenty minutes to a couple of hours.
To stop it coming back, the main fix is to lower your nicotine strength if it is too high for you, since a strength that is too strong is the usual trigger. Taking slower, shorter puffs and avoiding chain vaping helps your body keep pace, while not vaping on an empty stomach makes a difference too. If a liquid feels too strong, a lower strength nic salt is often more comfortable.
It is worth finding the lowest strength that still keeps your cravings in check. Too high and you risk the queasiness described here, too low and cravings can pull you back toward cigarettes, so a little adjustment up or down helps you land on the strength that feels right.

When to seek advice
Most cases are mild and pass on their own. If feeling sick is severe, will not settle, comes with vomiting that does not stop, chest tightness or trouble breathing, seek medical help, since those signs need proper attention rather than waiting it out.
It is also worth flagging a child safety point. Nicotine e-liquid can be very dangerous if swallowed, so if a child is ever exposed to it, seek urgent medical help straight away. For the everyday queasiness that comes with vaping too much or too strong, the steps above usually settle it, though if it keeps happening despite lowering the strength, a chat with a pharmacist or GP is sensible.
- Usually mild: nicotine queasiness tends to pass within an hour or two.
- Lower the strength: a strength too high is the most common trigger.
- Get help if severe: persistent vomiting or breathing trouble needs attention.
- Child safety: if a child swallows e-liquid, seek urgent medical help.
Does feeling sick mean I should stop vaping?
Not necessarily, though it is a clear signal to change something. If you have switched from smoking, the queasiness is usually a sign your strength or pace needs adjusting rather than a reason to go back to cigarettes. Lowering the strength and slowing down generally fixes it.
If you do not smoke and are finding vaping makes you feel unwell, the simplest answer is that there is no reason to keep at it, since vaping is meant for adult smokers quitting. Either way, persistent sickness despite the usual adjustments is worth raising with a pharmacist or GP to check nothing else is going on.

The bottom line: feeling sick from vaping is most often too much nicotine, which as a stimulant can cause nausea, dizziness and headache, made worse by chain vaping, an empty stomach or dehydration. It usually settles within an hour or two if you stop, drink water and rest. Lowering your nicotine strength prevents it. Severe or lasting symptoms need medical attention.

Is feeling sick a sign of too much nicotine?
Usually, yes. Nausea is one of the first signs of taking in more nicotine than your body is used to, alongside dizziness, headache, a racing heart or a wired feeling. It is your body asking you to slow down. If you often feel sick on your current strength, it is a sign to step down to a lower one.
Why do I feel sick after upping my nicotine strength?
Because your body is suddenly getting more nicotine than it is used to.
