Are you allergenic to e-cig propylene glycol?

If you are thinking of switching over to e-cig, you probably are wondering what is that you are going take into your lungs instead of those harmful tobacco smoke. The two most widely used e-liquid bases are propylene glycol or PG and vegetable glycerin or VG. Apart from the base, the liquid also consists of flavoring agents and nicotine. Both PG and VG and non toxic in nature and food grade chemicals and hence, are safe for consumption. These liquids are also used as additives in various other products.


Propylene glycol based e-liquid is more popular as compared to vegetable glycerin. PG is thin in consistency when compared to VG and hence, this is more easily absorbed by the fabric present inside the cartomizer. PG is a low density liquid that is tasteless and odorless and does not affect the taste of the e-liquid in any way. It will dry your mouth and throat if you smoke PG contained e-cig for a long time as it is a powerful humectants. But it has disadvantages as well and it is known to cause allergies in many e-cig users. Though this is fit for human consumption but that does not mean that few humans cannot be sensitive to it. After all, many people are also allergic to prawn, eggplant, peanut and loads of other things.

Some of the symptoms of PG allergy include:

  • Pungent smelling urine
  • Sore throat
  • Muscle pain
  • Headaches
  • Sinus problems
  • Nausea and few others.

In severe cases, PG can also cause hives in the upper part of your body and hence, if you are experiencing any of these symptoms, then you should stop using PG e-cig immediately and switch to VG contained electronic cigarette. Some people even complained about trouble in breathing, too much perspiration diarrhea and various symptoms that they experienced due to smoking e-cigs. But there is something that you need to understand.

Before you start guessing that whether the symptoms you are experiencing are due to the ingredients contained in your e-cig, you need to understand whether the symptoms are related to the fact that you are vaping. Many people who have recently given up smoking traditional cigarettes and switched to e-cigarettes experience few side effects due to the fact that they have given up tobacco smoking and these side effects include mouth ulcers, skin eruptions, coughing, headaches, nausea etc. All these symptoms go away within few days or a week or two and there is nothing that you should be worried about. The best ways to understand this is by stop consuming e-cigs for a few days and observe whether your general condition improves. If you stop experiencing those symptoms, them investigate on the type of e-liquid you are using as then you are probably allergenic to propylene glycol and if does not, it means that that side effect is due to tobacco cessation.

There is another thing that you need to understand and that humans do not just experience allergenic symptoms due to vaping as they can become allergenic to loads of other stuffs at any point of their lives. It means that even if you are happily smoking for many months, you suddenly can experience bizarre symptoms. PG is considered to be the only culprit as far as e-cig allergies is concerned. The only solution to this problem is to switch to e-liquid that contains 100% vegetable glycerin or at least contains maximum of it and very less percentage of PG.


One of the byproducts of PG is lactic acid and this is the same compound that is responsible for muscle pain and soreness due to heavy workout. If you are experiencing any of these symptoms, then you must avoid drinking too much water as that might alleviate the problems.

But if you do not experience any improvement by lowering the content of PG in your e-liquid or eliminating it completely, then you might be suffering from nicotine overdose. It might also happen that you are allergenic to the flavoring agents and other chemicals that are present in the e-liquid. Nicotine overdose can be serious and is associated with symptoms like dizziness, nausea, accelerated heartbeat, headache and sweating. If you are using an e-liquid that has a very strength of nicotine then switch to 0%-nicotine contained e-liquid immediately. And if you still do not see any improvement in your health condition, then medical help without any delay. But no matter, what do not get back to your older habit of smoking tobacco cigarettes.f
