Is Nicotine a Carcinogen?
The short answer is: no. Nicotine in cigarettes and other tobacco products certainly does not cause cancer.
You can overdose on nicotine if you have too much of it in your body. If your body’s nicotine levels are suddenly depleted, you’ll likely suffer from nicotine withdrawal. But nicotine itself is not a carcinogen, so it doesn’t cause cancer.
However, that doesn’t mean that nicotine is not a harmful chemical. Though nicotine does not directly cause lung cancer, it does have a hand in making you more prone to lung cancer and the other nasty health effects of chronic smoking. What nicotine does is cause addiction. It’s the main reason why you just can’t put down those cigarettes.
The bad news is that most regular cigarettes today contain tar, which is the primary contributor to smoking-caused cancer. Tar is a sticky, carcinogenic substance that is responsible for that distinct cigarette taste. Without tar, cigarettes would not taste as good, which results in poor cigarette sales. This is why cigarette manufacturers use tar in their products.
So the more cigarettes you smoke, the more nicotine you inhale into your body, and the more addicted you become to cigarettes. As you feed your nicotine addiction, more tar enters your body and you’re exposed to carcinogens such as benzene, acryalamide, and acrylonitrile. DNA in your lung cells mutate, and, before you know it, you’re well on your way to developing lung cancer.
You might be wondering: is there any way to get nicotine without tar? The answer is yes, there are nicotine products that are completely tar-free. These include nicotine patches, nicotine sprays, e-liquid for e-cigarettes and vaporizers, and nicotine lozenges. These products can give you a nicotine fix without the carcinogenic effects of tar.
So if quitting smoking together seems like a daunting effort for you, there are still some things you can do to minimize your risk of developing lung cancer. You can start trying smoking cessation products such as nicotine patches, nicotine spray, or nicotine gum and lozenges. These will help you wean yourself from regular cigarettes or other tobacco products. Smoking cessation products typically contain no tar and less nicotine.
You can also try switching to electronic cigarettes or e-cigarettes. Although you can still be addicted to the nicotine in the e-liquid used for these devices, the e-liquid contains no tar, so you can lower your risk for lung cancer. Many smokers have found great success in switching from cancer-causing regular cigarettes to vaporizers or e-cigarettes.
You also have the option to go for cigarettes that are said to have low levels of tar or nicotine. The downside of smoking these cigarettes is that they can cause smokers to just consume more cigarettes just to get their nicotine fix. You might also end up consuming more cigarettes just to get that cigarette flavor you’re used to. Smoking many low-tar cigarettes can be just as harmful as smoking a few regular-tar cigarettes.
As a smoker, your best bet to breaking free of nicotine addiction is still to quit smoking. Completely quitting smoking is not easy and, in some case, it’s not even always possible. But it gives you the best chance of staying away from all the negative health effects of smoking.
