Vaping Side Effects: What Every Vaper Needs to Know

So, you have taken up vaping or have switched to it from smoking. Is vaping completely safe for you? Although several studies have shown that vaping is a better alternative for smokers who find it hard to quit or who do not want to give up nicotine, e-cigs have their fair share of issues. Also, you may suffer some side effects if you switch.

The good news is that the side effects—which have been well studied—are milder and temporary. That is, they clear up within the first few weeks, or when proper actions are taken. Moreover, only a handful of people experience more severe side effects. What affects vapers most often are nicotine withdrawal side effects, but these are not brought about by vaping.

Smoking cessation side effects confused as vaping side effects

If you are a smoker and decide to start vaping, you will most likely reduce smoking cigarettes. The issues start from there, and as smoking is a better way of getting nicotine into your system, you will have a smaller supply. Consequently, you will experience nicotine withdrawal side effects, which you may assume to be vaping side effects. Even when you try to compensate for the lower nicotine supply by using e-liquids with higher nicotine levels, you will still be receiving less nicotine, and you will experience some problems in the initial stages.

Nicotine withdrawal side effects include the following:

  • Dizziness
  • Nausea
  • Sore throat
  • Sleep issues and insomnia
  • Fatigue
  • Coughing
  • Concentration and memory problems
  • Headache

The real vaping side effects

While vaping does have side effects, it is safer than smoking, as studies have demonstrated. You should ensure you buy quality and genuine vaping supplies from reliable and reputable vendors and manufacturers. You cannot go wrong buying from ePuffer.

Some vaping side effects include:


The main side effect of vaping is dehydration, thanks to the tendency of propylene glycol (PG) and vegetable glycerin (VG)—the solvents used in vape juice—drawing in moisture, keeping it, and making your throat and mouth too dry. Dehydration, even when it’s mild, may make you feel tired, weak, and unable to concentrate. The symptoms of dehydration are dry mouth and throat, dry skin, and itchy skin. To escape this, drink more water—10% more (an extra glass)—when vaping.


The cause of dizziness is an excess intake of nicotine, especially among smokers who have switched to vaping as they try to compensate for the lower nicotine level in e-cigs. Also, new vapers may experience dizziness due to a vaping style known as chain vaping, which gives you too much nicotine in a limited time. This common side effect is also known as being “nic-sick." Whenever you feel dizzy while vaping, put down the e-cig and focus on something else. Also, you should always find out the nicotine strength of your vape juice. You can vape for longer periods with vape juice that has 3-9 mg, but anything above these levels will call for taking more breaks and drinking lots of water.

Canker sores

Prevent canker sores

You should not mistake these for cold sores—they are tiny wounds that appear inside the mouth. They are brought about by many things, like spicy foods, hormones, stress, and vaping, among others. Canker sores are due to poor hygiene, not vape juice or vapor. You need to regularly and carefully clean your vaping device to rid it of vape juice gunk, dust, and tons of harmful micro-organisms that inhabit the mouth.


Besides the PG and VG, vape juices contain flavorings that can be naturally extracted or artificially manufactured. The flavorings include menthol, nuts and fruits, and even butter. Allergy issues are usually a result of these additives. If a vape juice causes you any kind of discomfort—tightening of the throat, for example—check out the ingredients, and find out if there’s something you’re reacting to. It is always prudent to buy vape juices from suppliers who disclose the ingredients. People who may be allergic to PG or VG should only buy vape juices that are purely PG or VG, depending on what they react to.


Vaping has side effects like dizziness, dehydration, canker sores, heartburn, allergic reactions, and more. Fortunately, these side effects clear up quickly, and after a few days, they are well known and easy to manage.
