Is Nicotine Bad?

If you spend time online, you know that a lot of health news is accompanied by attention grabbing “click bait” headlines.  Paranoia sells and it gets lots of readers. So you may have rightly started to distrust news stories that talk about the latest dangers to your health. After all, everything from air to gluten has been linked to serious health risks. You may now be wondering just how bad nicotine really is for your health. Here are some things to consider about the risks associated with nicotine.

Damage is Cumulative

It’s a misconception that cigarettes labeled as “lights” or “milds” are somehow safer than other cigarettes. As a popular joke about those products goes, there’s no such thing as light or mild cancer! Light or mild in describing cigarettes actually refers to the taste of the tobacco, not in the concentration of the nicotine within the tobacco.

In 2009, the U.S. Senate passed a law stating that the Food and Drug Administration had the authority to regulate all tobacco products. As part of this legislation, the FDA also cracked down on the tobacco industry’s marketing efforts, and tobacco companies can no longer refer to cigarettes as “mild” or “light,” largely because of the misconception that labeling created, which suggested that such cigarettes were less dangerous.

Although there is no safe level of nicotine, it appears that the damage from nicotine consumption adds up over time. The more cigarettes that you smoke and the longer that you’re a smoker, the more affected you will be by nicotine.

Nicotine Side Effects

There are countless side effects of nicotine, most are common but not very dangerous while a few uncommon ones can be hazardous. Moreover, some nicotine effects are dependent on the way you take it. For example, skin rashes, red patches, swelling or itchiness are caused by using nicotine patches; mouth, tooth, jaw, or neck pain are usually attributed to chewing tobacco; and watery eyes, cough, and lung irritation occur mainly as a result of smoking tobacco.

Severe Side Effects of Nicotine

If you experience any of these side effects, you should seek prompt medical help. Usually, these occur after an overdose and can have grave consequences on your health, if not treated in time.

  • Fast or uneven heartbeat
  • Chest pain
  • Seizures
  • Severe rash or swelling

Common Side Effects of Nicotine

Common nicotine side effects appear when you initially start taking nicotine and gradually disappear as your body gets accustomed to it. While the common side effects might not be dangerous, but you should still talk to your doctor if any of these persists or starts to get worse.

  • Cough
  • Sneezing
  • Headache
  • Constipation
  • Diarrhea
  • Dizziness
  • Heartburn
  • Watery eyes
  • Sudden change in tastes
  • Dry mouth
  • Acid or sour stomach
  • Hiccups or belching
  • Throat sores or mouth sores, blisters, or irritation
  • Upset stomach, nausea or vomiting
  • Mouth, tooth, jaw, or neck pain
  • Problems with teeth
  • Unusual tiredness or weakness

Negative Heart Effects

You also need to take your personal health history into consideration when evaluating the risks of nicotine. If you are already diabetic or have a family history of diabetes, smoking is an especially dangerous habit to take up. Nicotine raises your blood sugar, which can make it much harder to control your diabetes if you’re already diabetic, or it can be the factor that tips the balance between being pre-diabetic and developing full blown diabetes. When you’re diabetic, poor blood sugar control significantly increases your other risks from the disease, including heart attacks and stroke.

Nicotine also raises your blood pressure, which further increases your risk of having a heart attack or stroke. The stimulant effect that nicotine gives you is responsible for that slight “buzz” feeling, which can be pleasurable in the sense of boosting your energy, but it also causes your heart to beat harder and faster.  When your heart beats harder and faster on an everyday basis, eventually it causes your blood pressure to go up. High blood pressure isn’t just a harmless state, either: it’s a sign that your heart has to work too hard just to perform the daily functions it needs to do to keep you alive.

In this case, it’s not the smoking that causes the changes to your blood sugar and blood pressure, it’s the nicotine itself. If you were to switch to using a nicotine patch or smokeless tobacco (also called chew or dip) instead, for example, you would still have the same harmful effects from the nicotine.


Negative Lung Effects

Smoking is one of the worst things you can do for your lungs, especially if you have health conditions like asthma or allergies that already compromise your lung health.

Smoking causes your airways to swell up and tighten, which makes it harder for air to get through your lungs. Cold weather has a similar effect on your lungs, which you may have noticed if you go outside to have a cigarette during the winter. The double effects of nicotine and cold weather can make you feel like you can’t breathe or get enough air.

Over time, these risks to your lungs can add up to developing serious chronic lung diseases, including Chronic Obstructive Pulmonary Disease (COPD), emphysema, and even lung cancer.


Preoccupation with Smoking

Nicotine is so powerfully psychologically and physically addictive that you’re always thinking about when you can have your next cigarette, even if you just had one. This causes a lot of anxiety for smokers! It’s really distracting to be in an unfamiliar or new situation where you know that you cannot maintain your normal smoking habits. For example, if you have jury duty or have to go to a family member’s house who doesn’t allow smoking, you’ll probably find that you can’t stop thinking about when you can have a cigarette again. Stress and smoking seems to be a vicious cycle, because most smokers say that it relieves their stress to have a cigarette, but smoking another one keeps the cycle in motion.


The Positive Side

Although there are plenty of negative effects associated with nicotine as mentioned above, the substance does have some positive effects, too. Pharmaceutical researchers are currently studying possible uses for nicotine in improving cognitive function and memory in seniors with Alzheimer’s disease and in people with schizophrenia.  Nicotine may also be beneficial in preventing Parkinson’s disease.

Other researchers at Stanford University made the surprising discovery that nicotine actually helps the body to grow new blood vessels. Although this is a double-edged sword because smoking also damages blood vessels, researchers are considering how nicotine could be used in a positive manner to promote the growth of new blood vessels as well.

Many patients with ulcerative colitis have also found relief from their condition with the use of nicotine patches, and for a while, nicotine patches were prescribed off label for this purpose.

Nicotine also helps to improve mood, which can help people who have mood disorders like depression and anxiety.

On the whole, nicotine seems to have more negative effects than positive ones. However, it appears that many of the risks of nicotine are greatest in those who smoke because the accompanying damaging effects of smoking are substantial contributing factors.


  1. I have a vape and I usually use 3mg of nicotine vape juice. Is that harmful? if it is how long is it actually gonna take for my lungs to suffer?

  2. Nicotine is not bad for your health. This entire article is basically a massive hyperbole. Caffiene has the EXACT same effects to the body as nicotine does (other than the effect on blood sugar). Yet you don’t see all the bad stigma on coffee as you do on nicotine. Nicotine gets it’s bad reputation from smoking. Smoking is bad for you, along with other forms of tobacco (and maybe vapes?) BUT nicotine in itself is actually not bad for you! Yes it is addictive, but so are alot of other things like eating comfort foods and, yea, coffee. Just because it’s addictive does not make it bad. P.S: Yes this means nicorette not harmful to your body whatsoever. Note: Nicotine is not a carcinogen.

  3. Joe, before you die it`s recommended that you donate your savings to a lung cancer society to help people like you who are between life and death.

  4. Joe, are you die yet?
    If no then sorry to say this but you should treat your short remaining lifespan better. And don’t forget to leave your last letter for your family just in case.

  5. Joe, are you serious? I understand the article doesn’t treat nicotine very nicely but the truth is nicotine in itself doesn’t kill you (unless you overdose on it, which takes a really huge amount) and is in many ways similar to caffeine. Now, smoking tobacco (or anything else for that matter) is a totally different thing…

  6. We are all gonna die eventually! Even if it’s not from smoking, I just transitioned from smoking cigarettes to smoking ecigs only 6 weeks ago and I actually can see and feel a big difference!

  7. Try vaping, it got me off cigarettes in 2 days after 55 years of smoking. It’s a much more efficient nicotine delivery system without all the cigarette side effects. The cigarette look-alike convenience store stuff is useless. Search youtube for videos and reviews of vaping starter kits and go from there. Any thing mentioning vaping 101 will be good info also. There is a little learning curve involved but your lungs will thank you for it. The has been a recent study that says some of the components of vegetable glycol (which is a completely safe food-grade ingredient), which is used in the manufacture of e-juice, when burned at extremely high temperatures, can release some toxins. However, the temps stated would be like sucking on a blowtorch, which I doubt any vaper would be able to or want to run at such high temps.

  8. we will always have a problem with recreational drugs when there is so much wrong, so called scientific information on the web. Nicotine is as bad for you as Caffeine FACT vaping has 95% less toxins than tobacco FACT

  9. Vaping is in fact a “better” alternative to cigarettes, however if you want to quit smoking it’s not. Your still inhaling a substance that sticks to your trachea and lungs (with or without nicotine). I would recommend lozenges! They actually work for people who struggle with the nasty habit of smoking. Fuck the gum and the patches. I found that the patches itch amd the gum upsets the stomach (unless you place it under your lip) a big plus with the lozenges is that you look as if your not a smoker lmao. Its all bad. Positive benefits? Yeah maybe if your one one of the special cases. wish you all the best of luck and remember it’s will power not alternatives.

  10. I hate to say this, but you are wrong. Unless you vape oil with no nicotine you are still getting all the harmful effects of nicotine.

  11. I stopped smoking after 11 years. I quit drinking, and smoking gave me anxiety during the withdrawals, and so I had to cut it back to stop freaking out. After not smoking for a few days, I realized how much I hated smoking. I had one cigarette, and I felt the addiction – the positives and negatives – all at once and realized I didn’t want to be addicted to anything anymore…

    Seriously, quit. It’s soooooooooooo much better.

  12. To think that we live in a world where, someone asks a simple question, and instead receive ludicrous comments. No Jo, you will be fine, but that much nicotine might make you feel a little sick or uneasy. But, you will not die from it. Its also not a good thing to do, so if you can stop please do so. Long term Nicotine use is not good for anyone, and it does have side effects as we all know.

  13. Vaping is def a great option as it helped me quit a 30 year habit in a week. Don’t go over 6 nicotine though. For me, going over 6 caused the same ill effects as smoking – shortness of breath, pain in chest, wheezing. Staying under 6 seems to bring the “positive” effects as mentioned in the article. It does have a learning curve as mentioned before so find a reputable Vape shop, research online, ask friends if you can. P.S. Joe, I hope you are still with us 😀

  14. Lol. One more here for vapor. I smoked 46 years. I weened off cigs to finally vapor only. I have now cut my nicotine strength down also. However, I think I’ll continue vaping. I enjoy it and all those negative side effects of nicotine? Maybe I’m lucky, but I’ve never experienced any of them. To me nicotine is just weak caffeine. It’s a central nervous system stimulant. Being a speed freak of old, lol, I appreciate stimulants. And – ahem – no, they don’t explode.

    • There are not really any side effect of nicotine…the article is mainly taking about smoking….. you just carry on as you are… good for you, stopping smoking and adding an extra 10 years to your life!
