Nicotine side effects

Most vapers at one time or another experience the effects of vaping too much nicotine. Because we self-titrate — meaning we vape nicotine until we have the effect we want and then stop — it can be easy to misjudge, especially if you're trying an e-liquid in a stronger concentration than you're used to, or using an atomizer that delivers more vapor than you're used to.

We're not really concerned here with the effects of a nicotine overdose, since that is easily avoided by not drinking nicotine in high concentrations. An adult would have to absorb 500 mg or more of nicotine to die, according to Prof. Bernd Mayer. But you weren't planning on doing that anyway, right?

The typical effects of vaping too much nicotine are probably familiar to you already:

• Dizzy or lightheaded 
• Headache 
• Nausea 
• Cold sweats 
• Insomnia 
• Racing heart 
• Anxious or jittery 
• Ringing ears

If you start to feel any of those things, stop vaping for a while. They’ll go away. If you constantly suffer those side effects, either vape less or lower your nicotine level.
