Like pretty much anything else we ingest or inhale, not everybody reacts in the same way to the constituents of e-liquid and the resulting vapor. In most cases, the only side effect is some minor throat irritation, but for some people it can be much worse.

 Finding out about the potential reactions you can have to e-liquid, food (Nuts), medications or conditions which may have an interaction with nicotine and the advice is regarding pregnancy and e-cigs helps you stay safe when you’re vaping.

 Of course, this is for information only; if you’re concerned about any of the topics covered here – but understandably doesn’t want to go back to smoking – you should see your doctor and follow his or her advice.


Key Points


  • Some vapers are allergic to PG, but it’s possible to be allergic to the other components of e-liquid too. Watch out for symptoms such as hives, rashes, wheezing, coughing, sore throat, nausea, headaches, swelling and itchy eyes.
  • Avoid any flavorings that likely contain nut derivatives or cause an issue based on your experience with food.
  • Check with your doctor if you have a heart condition, asthma, insulin-dependent diabetes, hyperthyroidism or other conditions such as psoriasis, or if you’re taking medicines like tricyclic antidepressants or theophylline.
  • E-cigs are unlikely to be as dangerous when pregnant as smoking, but still carry some definite risks; only use if abstinence is impossible, and minimize nicotine consumption as much as you can.
