Why does vaping make me feel sick?

What nicotine sickness feels like

Nicotine is both a stimulant and a toxin. In low doses it gives the familiar buzz. In higher doses it overwhelms your nervous system and digestive system, producing a set of symptoms collectively called nicotine sickness or nic-sick.

The symptoms are unmistakable once you have had them. Nausea, dizziness, sweating and a general feeling of being unwell that comes on within minutes of vaping more than your body can handle.

Common symptoms of nic-sick include:

• Nausea ranging from mild queasiness to active vomiting.
• Dizziness or lightheadedness, sometimes feeling like the room is spinning.
• Headache that comes on during or shortly after vaping.
• Cold sweats and clammy skin.
• Rapid or irregular heartbeat.
• Stomach cramps or a feeling of churning in the gut.
• Confusion or difficulty concentrating.
• Feeling generally unwell in a way that is hard to describe but obviously off.

The main triggers

Why new vapers feel sick more often

If you are new to vaping or switched from smoking recently, you are particularly likely to feel sick. A few reasons.

• Higher nicotine absorption than smoking. Vaping, particularly with nic salts, delivers nicotine to the bloodstream very efficiently. You can absorb more than you used to from cigarettes without realising.
• Continuous use is easier. Cigarettes burn out. Vapes do not. Without that natural stopping point, it is easy to take more puffs than your body wants.
• No combustion cues. Smoke is harsh enough that you naturally stop after a cigarette. Vapour is smoother, which means there is no warning signal when you have had enough.
• Body is still adjusting. Your tolerance to vaped nicotine builds in the first few weeks. Symptoms that hit you on day 1 will often be much milder a month later.

What to do when you feel sick

1. Stop vaping immediately

   Do not take another puff. Put the device down. The single most important thing is to stop adding more nicotine to your system.

2. Sit or lie down

   Particularly if you are dizzy. Lying down reduces the risk of fainting. Stay still for 10 to 15 minutes.

3. Drink water

   Sip cool water steadily. Helps with both the nicotine effect and any dehydration that is contributing.

4. Eat something light

   Plain crackers, dry toast or a banana. Helps stabilise blood sugar and slows further nicotine absorption.

5. Open a window or get fresh air

   Improves oxygenation and helps the dizziness pass faster.

6. Wait it out

   Most nic-sick episodes pass within 30 to 60 minutes. Severe cases can last 2 to 4 hours. The half-life of nicotine is about 2 hours, so symptoms steadily reduce.

How to prevent it happening again

1. Lower your nicotine strength

   The biggest preventive change. Going from 20mg salts to 10mg, or 12mg freebase to 6mg, dramatically reduces nicotine sickness risk while still satisfying cravings.

2. Take shorter, slower puffs

   Each puff delivers less nicotine. Easier for your body to handle.

3. Wait between puffs

   Aim for 30 to 60 seconds between draws. Wait 5 to 10 minutes between full sessions. Stops nicotine stacking up.

4. Don't vape on an empty stomach

   Have a small breakfast or snack before your first vape of the day. Slows absorption and prevents the morning nic-sick that catches many people out.

5. Stay hydrated

   2 litres of water a day, more on heavy vaping days. Reduces the dehydration component that often makes nicotine sickness worse.

6. Learn your limit and respect it

   Your body will tell you when you have had enough. The slight lightheadedness or queasiness that comes before full nic-sick is the warning. Stop there.
