Seven Quit Smoking Side Effects: The Essential Guide for New Vapers and Quitters

Although this is an electronic cigarette blog, I think this is an important post for both smokers quitting and for new vapers (electronic cigarette users).

That’s because while some vapers switch to e-cigarettes effortlessly, others struggle, and some get withdrawals symptoms (especially those using zero nicotine electronic cigarettes).

This year I’ve heard two people complaining of mouth ulcers from vaping. While there may well be side effects from quitting vaping – we do that know a very small minority of people are allergic to propylene glycol, and that it can cause sore or dry throats – some reported side effects are also identical to those caused by quitting smoking.

So here’s an overview of what to expect when you stop using tobacco cigarettes!

1. Mouth Ulcers after Quitting Smoking

According to the NHS site, quitting smoking leads to a change of chemicals in your body, which can in turn cause more mouth ulcers than normal. There are other causes, so check out the NHS page on mouth ulcers if it is a worry.

2. Coughing, Chest Pains and Respiratory Problems

Quitting smoking can also lead to (temporary) respiratory problems: sharp chest pains, coughing and cold/flu like symptoms e.t.c. A number of sites attribute this to the body clearing itself up. But if you’re worried, get it checked out!

3. Fainting


I remember talking to an athlete in Greece who was a heavy smoker. She decided to quit smoking – and fainted in the street. (Being in Greece, her doctor recommended that she keep smoking, which I don’t think you would get in the UK.)

There’s precious little information about this on the net, so this may be a rare incidence, although other quitters have reported feeling faint.

4. Mood

Nicotine makes the brain release dopamine, helping us to feel good. Smoking can also help to calm us or to stimulate us (see Nicotine and Electronic Cigarettes: 10 Facts All Users Should Know.) So it’s not suprising that if you are getting no or less nicotine you can experience mood swings, depression and anxiety.

5. Weight Gain

Smoking helps control weight – and some of this may be attributable to nicotine, with some vapers reporting electronic cigarettes help control weight and others less sure. From a personal level, I find vaping/smoking is something to do when you are bored, so you may find you eat when you would otherwise smoke.

In one poll we are running on facebook, 49% of reported feeling less hungry when they vaped, with 14% reporting  no effect and 37% unsure.

6. Sleepiness OR Problems Getting to Sleep

Another quit smoking side effect I recently ran across (have you experienced this?) is problems with sleep. Quitting smoking can cause either sleepiness or insomnia, and has been reported by vapers who have only recently quit smoking.

Fatigue generally only lasts for a couple of weeks or so, so if it persists after this time it might be worth checking with your doctor.

7. Headaches

Both smokers in the process of quitting and vapers switching to ecigs have reported getting headaches. I’ve seen various reasons given for this, including oxygen levels in the blood returning to normal and because of the body’s cravings for more nicotine.

It could also be linked to other changes brought on by quitting smoking, such as a lack of sleep or increased coffee drinking.

Other Symptons

Yes, there’s more! Quitters have also reported:

  • Nausea
  • Lack of Concentration
  • Loneliness
  • Frustration
  • Fatigue
  • Dizziness
  • Depression
  • Constipation
  • Stomach Aches

What to do if you experience side effects?

If you’re really worried about any side effects from quitting smoking/taking up vaping – don’t read a blog post – most of us bloggers are not medical experts, so get advice from a real doctor 😉

  1. Insomnia for me. Been on the vape around six weeks now and I’m still not sleeping properly. Looks like ill be paying my GP a visit soon!

  2. I bought an e-cig for myself as an Xmas present, as smoking has given me allergic rhinitis and a permanent cough. Originally I planned to use it in combination with smoking to reduce how much I smoked but I didn’t have the willpower to use both.
    I finally decided I needed to stop smoking altogether and only vape, and 4 days in it’s going great. It’s never been this easy when I’ve quit smoking a couple of times before, and I’d recommend this method to anyone thinking of quitting.

  3. Gave up smoking with remarkableease due to gaping! Honestly never missed my cigs after 30 years of smoking! Give it a try

  4. I gave up 6 weeks ago with e vape after 30yrs of smoking had some mouth issues blood returning to my mouth trying to heal and my tongue is really sensitive to spicy foods im just plodding on and perserviring my husband still smokes and im not at all botherd by it good luck with quitting every one.

  5. Smoking 40 ciggs daily bought vaping e cigg never looked back . smoked for 50 years. cud not have done it without it. Chest feeling fantastic now. ALL my family amazed side effects coming off the ciggs and vaping mouth sores headaches. 9 weeks now never will I smoke again I am adamant.

  6. well smoked cigs for 31 yrs, 20 a day roughly, went to vaping started on 26mg now down to 3mg for the past 6mths. went to pack in cold turkey completely 2 days in felt very unwell, nausea couldn,t sleep for feeling sick resulting to going back to vaping gutted. years ago when packing in cigs cold turkey never felt like that so makes me think what is in the liquid that can make you feel so unwell scary.
