E-Liquids Loading... Please wait...

Are there any side effects of vaping?

E-liquids consist of three major components: a VG/PG base, nicotine and flavouring.  As a result, vaping may have some side effects, which can vary from a dry mouth to other health concerns. If the e-juice contains nicotine, this adds further aspects to any reactions, especially if the user had never smoked cigarettes or been exposed to other nicotine forms. Even the safest food items we enjoy can lead to health concerns or adverse effects.

Listed below, we provide a few of the more frequent side effects of vaping:

Dry Mouth:

Among the most common effects of vaping. A dry mouth is mainly related to the base active ingredients of e-liquid: PG and VG (Propylene Glycol and Vegetable Glycerin).

Greater percentages of propylene glycol in e-liquid are reported to have a more drying effect in the mouth, and it's not uncommon for some vegetable glycerin vapers to experience this as well. If you have a dry mouth, you can use an oral hydration rinse or make a point of drinking more water.  These two treatments are probably the simplest way to get moisture levels corrected in your mouth.  Should this persist, you must talk to an oral health provider, as this can be a symptom of dehydration and, if neglected, can trigger other oral health issues.


Too much nicotine exposure can cause lightheadedness. If you're feeling woozy, you're probably consuming more nicotine than your body can handle. This impact is typically connected with sub-ohm vaping when giant plumes of vapour are entering your body. Luckily, dealing with this problem is just a matter of changing to an e-liquid with a lower nicotine strength or vaping at a greater resistance.

Sore throat:

A sore or raspy throat may be caused by several factors: nicotine, propylene glycol, flavourings, or even the coil used in the atomiser. Certain coils in vaping kits are nickel-based, and it's not unheard of for users to discover they have a sensitivity to nickel. Some online reports can be found which associate a sore throat with higher nicotine, especially when utilised with high levels of propylene glycol. If you suspect these issues are due to the e-liquid, try a greater percentage of vegetable glycol (VG), a new flavour-- like menthol or spearmint juice-- or experiment with lowering the nicotine concentration.


Issues with coughing whilst vaping have emerged from newbie vapers, even if they're ex-smokers or current cigarette smokers. A contributing factor to vaper's cough could be the actual quantity of nicotine in the e-liquid. On top of that,  another reason for coughing is merely the technique employed. Many smokers use the method where they breathe in the smoke straight into the lungs. With vaping, it's advised to use the mouth to lung (MTL) technique, where you draw the vapour into your mouth, hold it and then breathe it in. Using a direct to lung (DTL) method when vaping is probably going to cause some coughing. This is because cigarette smoke contains anaesthetics designed to reduce throat inflammation, whereas vapour does not.


As you know, almost every e-juice has a PG/VG base.  Even though it's considered safe, PG can set off a few allergies. VG, on the other hand, has been derived from vegetables and is gentle on the body.  So, if you're vaping higher PG e-liquids and experience allergies, switching over to a high VG e-liquid can be helpful.

Weight gain or loss:

There is no evidence vaping will assist in weight reduction or lead to weight gain, even if nicotine is used.  Nicotine is thought to be an appetite suppressant, particularly in the context of smoking; there isn't much conclusive proof to show it's the effectiveness with losing weight. It's good to remember that nicotine is a stimulant, and other stimulants (like caffeine) are also connected to weight loss by enhancing your metabolic rate. That's not to say weight loss won't take place from vaping, but it's certainly not a natural side effect.


The description of vaping headaches vary, but is mainly referred to as a low level or a dull headache. These headaches are most reported amongst new vapers. Take comfort that the headaches will get less regular and eventually subside.

There are a handful of reasons which may induce vaping headaches:

The first is the level of nicotine, as it restricts blood capillaries and impacts the nerve system.  Nicotine is also a stimulant that could cause lightheadedness if you are not used to larger amounts. If you have smoked cigarettes before, it may not be that obvious unless you use an exceptionally high nicotine concentration whilst vaping.  Another potential trigger for headaches is propylene glycol (PG). This is a natural substance and is part of the four ingredients used in e-liquid. It has the unique property of transforming into vapour when heated, which allows inhalation.  PG draws moisture from its environment, and this can trigger headaches.

Vaping side effects: a perspective:

A lot of side effects from vaping are, in fact, adverse effects from nicotine usage. A few of these are particular to vaping itself. It would be beneficial to  remember that e-cigs are not health products and are a much safer option than smoking cigarettes.  If you are among the millions who have rejected smoking and have replaced it with vaping, the mild effects of vaping need to be viewed in comparison to cigarette smoking hazards.
