Nicotine and tobacco

Withdrawal from nicotine; Smoking - nicotine addiction and withdrawal; Smokeless tobacco - nicotine addiction; Cigar smoking; Pipe smoking; Smokeless snuff; Tobacco use; Chewing tobacco; Nicotine addiction and tobacco

The nicotine in tobacco can be addictive like alcohol, cocaine, and morphine.

Causes

Tobacco is a plant grown for its leaves, which are smoked, chewed, or sniffed.

Tobacco contains a chemical called nicotine. Nicotine is an addictive substance.

Millions of people in the United States have been able to quit smoking. Although the number of cigarette smokers in the United States has dropped in recent years, the number of smokeless tobacco users has steadily increased. Smokeless tobacco products are either placed in the mouth, cheek, or lip and sucked or chewed on, or placed in the nasal passage. The nicotine in these products is absorbed at the same rate as smoking tobacco, and the potential for addiction is still very strong.

Both smoking and smokeless tobacco use carry many health risks.

Symptoms

Nicotine use can have many different effects on the body. It can:

  • Decrease the appetite -- Fear of weight gain makes some people unwilling to stop smoking.
  • Boost mood, give people a sense of well-being, and possibly even relieve minor depression.
  • Increase activity in the intestines.
  • Create more saliva and phlegm.
  • Increase the heart rate by around 10 to 20 beats per minute.
  • Increase blood pressure by 5 to 10 mm Hg.
  • Possibly cause sweating, nausea, and diarrhea.
  • Stimulate memory and alertness -- People who use tobacco often depend on it to help them accomplish certain tasks and perform well. 

Symptoms of nicotine withdrawal appear within 2 to 3 hours after you last use tobacco. People who smoked the longest or smoked a greater number of cigarettes each day are more likely to have withdrawal symptoms. For those who are quitting, symptoms peak about 2 to 3 days later. Common symptoms include:

  • Intense craving for nicotine
  • Anxiety
  • Depression
  • Drowsiness or trouble sleeping
  • Bad dreams and nightmares
  • Feeling tense, restless, or frustrated
  • Headaches
  • Increased appetite and weight gain
  • Problems concentrating

You may notice some or all of these symptoms when switching from regular to low-nicotine cigarettes or reducing the number of cigarettes you smoke.

Treatment

It is hard to stop smoking or using smokeless tobacco, but anyone can do it. There are many ways to quit using tobacco.

There are also resources to help you quit. Family members, friends, and co-workers may be an important source of support. Quitting tobacco is hard if you are trying to do it alone.

To be successful, you must really want to quit. Most people who have quit smoking were unsuccessful at least once in the past. Try not to view past attempts as failures. See them as learning experiences.

Most smokers find it hard to break all the habits they have created around smoking.

A smoking cessation program may improve your chance for success. These programs are offered by hospitals, health departments, community centers, work sites, and national organizations.

Nicotine replacement therapy may also be helpful. It involves the use of products that provide low doses of nicotine, but none of the toxins found in smoke. Nicotine replacement comes in the form of:

  • Gum
  • Inhalers
  • Throat lozenges
  • Nasal spray
  • Skin patches

You can buy many types of nicotine replacement without a prescription.

Your health care provider can also prescribe other types of medicines to help you quit. Varenicline (Chantix) and bupropion (Zyban, Wellbutrin) are prescription medicines that affect the nicotine receptors in the brain.

The goal of these therapies is to relieve cravings for nicotine and ease your withdrawal symptoms.

Health experts warn that e-cigarettes are not a replacement therapy for cigarette smoking. It is not known exactly how much nicotine is in e-cigarette cartridges, because information on labels is often wrong.

Support Groups

Your provider can refer you to stop smoking programs. These are offered by hospitals, health departments, community centers, work sites, and national organizations.

Outlook (Prognosis)

People who are trying to quit smoking often become discouraged when they do not succeed at first. Research shows that the more times you try, the more likely you are to succeed. If you start smoking again after you have tried to quit, do not give up. Look at what worked or did not work, think of new ways to quit smoking, and try again.

Possible Complications

There are many more reasons to quit using tobacco. Knowing the serious health risks from tobacco may help motivate you to quit. Tobacco and related chemicals can increase your risk for serious health problems such as cancer, lung disease, and heart attack.

When to Contact a Medical Professional

See your provider if you wish to stop smoking, or have already done so and are having withdrawal symptoms. Your provider can help recommend treatments.

    Smoking tips to quit - Animation

    You probably know by now that smoking damages your lungs, raising your risk for bronchitis, emphysema, and lung cancer. And, you're probably well aware that lighting up also puts you at risk for many different types of cancers, as well as eye disease like cataracts and premature wrinkles, you know why you shouldn't smoke, it's just the quitting part you can't seem to get past. Let's talk about some helpful tips to help you quit smoking, for good this time. It's a familiar story, one that plays out over and over again among smokers. You vow to quit, and you have every intention of doing it, and then the cravings hit. And you can't think about anything but having a cigarette. You get irritable, and you start putting on weight. You think, Just one cigarette wouldn't hurt, would it? And then, before you know it, you're smoking again. Most smokers have tried to quit, and failed, several times. Even if you've failed before, you can still succeed at quitting. Many people have. You just need to find the technique that works for you. So, here are a few tips that can help. First, set a quit date. Write it down on your calendar and tell a few friends, so you'll be too embarrassed to back out. Before your quit date, throw out every cigarette in your house, car, and office. Also toss every ashtray, lighter, and anything else you need to smoke. Wash your clothes and clean your furniture so you won't have that smoky smell hanging around your house. Next, call your doctor. Ask about smoking cessation programs in your area. Also learn about tools that can help you quit, like medicines that reduce the urge to smoke, and nicotine replacement gums, lozenges, patches, and sprays. And then, plan what you'll do instead of smoking. If you smoke with your morning cup of coffee, drink tea or go for a walk instead. If you need a cigarette to keep your mouth busy, try chewing sugarless gum or nibble on a carrot stick. Stick to places where smoking isn't allowed, like smoke-free restaurants. And finally, reward yourself for not smoking. Put all that money that you would have spent on cigarettes into a jar. And once you've collected enough money, use it to take a trip or buy something you've wanted for a long time. Don't get discouraged. Quitting smoking isn't easy. If it were, everyone would have done it by now. Be persistent, reward yourself for the progress you've made, and keep at it until you finally conquer the urge to smoke.
