Treatments and drugsBy Mayo Clinic staff
Smoking is the single most preventable cause of death in the U.S. Your health will benefit almost immediately if you stop smoking. Younger smokers who stop can have a normal life expectancy, and even older smokers who stop add years and quality to their life expectancy.
According to a report of the Surgeon General, a year after quitting, your risk of a heart attack drops sharply. After two to five years, your stroke risk may be reduced to that of a nonsmoker. And at 10 years, your risk of cancer may be reduced to about half that of a smoker.
Like most smokers, you've probably made at least one serious attempt to stop. But it's rare to stop smoking on your first attempt — especially if you try to do it without help. You're much more likely to stop if you use medications and counseling, which have both been proved effective, especially in combination.
Many treatments, including nicotine replacement therapy and non-nicotine medications, have been approved as safe and effective in treating nicotine dependence. Using more than one medication may help you get better results. For example, combining a longer acting medication with a short-acting nicotine replacement product may be beneficial. Talk to your health care provider about the right treatment for you.
If you're pregnant or breast-feeding, you smoke fewer than 10 cigarettes a day, or you're under age 18, talk to your doctor before taking any over-the-counter nicotine replacement products.
Nicotine replacement therapy
Nicotine replacement therapy gives you nicotine without the other harmful chemicals in tobacco smoke. Many people mistakenly believe that nicotine causes cancer, but that's not the case.
Nicotine replacement medications, including patches, gum, lozenges, nasal spray and inhaler, can help relieve difficult withdrawal symptoms and cravings. The best time to start using nicotine replacement medication is on the date you've set to stop smoking. Some smokers start earlier in order to reduce smoking on their way to stopping altogether.
Most nicotine replacement products are available over-the-counter:
- Nicotine patch (NicoDerm CQ, Habitrol, others). The patch delivers nicotine through your skin and into your bloodstream. You wear a new patch each day. The treatment period usually lasts for eight weeks or longer. If you haven't been able to stop smoking completely after two weeks or so of treatment, ask your doctor for help in adjusting the dose of the patch or adding another medication.
- Nicotine gum (Nicorette, others). This gum delivers nicotine to your blood through the lining of your mouth. It's available in a 2-milligram (mg) dose for regular smokers and a 4-mg dose for heavy smokers. Nicotine gum is often recommended to curb cravings. Chew the gum for a few times until you feel a mild tingling or peppery taste, then park the gum between your cheek and gumline for several minutes. This chewing and parking allows nicotine to be gradually absorbed in your bloodstream. Avoid drinking or eating right before, while using, or right after nicotine gum. The goal is to reduce the amount and eliminate the need for the gum in about three months.
- Nicotine lozenge (Commit, Nicorette mini lozenge). This lozenge dissolves in your mouth and, like nicotine gum, delivers nicotine through the lining of your mouth. The lozenges are available in a 2-mg dose for regular smokers and a 4-mg dose for heavy smokers. Place the lozenge in your mouth between your gumline and cheek or under your tongue and allow it to dissolve. You'll start with one lozenge every one to two hours and gradually increase the time between lozenges. Avoid drinking anything right before, while using or right after the lozenge.
These nicotine replacement products are available by prescription:
- Nicotine nasal spray (Nicotrol NS). The nicotine in this product, sprayed directly into each nostril, is absorbed through your nasal membranes into your blood vessels. The nasal spray delivers nicotine a bit quicker than gum, lozenges or the patch, but not as rapidly as smoking a cigarette. It's usually prescribed for three-month periods for up to six months. Side effects may include nasal irritation.
- Nicotine inhaler (Nicotrol). This device is shaped something like a cigarette holder. You puff on it, and it delivers nicotine vapor into your mouth. You absorb the nicotine through the lining in your mouth, where it then enters your bloodstream. Common side effects are mouth or throat irritation and occasional coughing.
Medications that don't contain nicotine include:
- Bupropion (Zyban, Wellbutrin). The antidepressant drug bupropion increases levels of dopamine and norepinephrine, brain chemicals that are also boosted by nicotine. Bupropion may be prescribed along with a nicotine patch. Typically your doctor will advise you to start bupropion one week before you stop smoking. Bupropion has the advantage of helping to minimize weight gain after you quit smoking. Side effects may include sleep disturbance and dry mouth. If you have a history of seizures or serious head trauma, such as a skull fracture, you shouldn't take this drug.
- Varenicline (Chantix). This medication acts on the brain's nicotine receptors, decreasing withdrawal symptoms and reducing the feelings of pleasure you get from smoking. Typically your doctor will advise you to start varenicline one week before you stop smoking. Potential side effects include nausea, headache, insomnia and vivid dreams. Rarely, varenicline has been associated with serious psychiatric symptoms, such as depressed mood, agitation and suicidal thoughts.
- Nortriptyline (Pamelor). This tricyclic antidepressant has been shown to help smokers stop. It acts by increasing the levels of the brain neurotransmitter norepinephrine. It may be prescribed if other medications for stopping tobacco use don't help. Side effects may include dry mouth.
Counseling, support groups and other programs
Combining medications with behavioral counseling provides the best chance for establishing long-term smoking abstinence. Medications help you cope with withdrawal symptoms, while behavioral treatments help you develop the skills you need to avoid tobacco over the long run. The more time you spend with a counselor, the better your treatment results will be.
Several types of counseling and support can help with stopping smoking:
- Telephone counseling. No matter where you live, you can take advantage of phone counseling to help you give up tobacco. Every state in the U.S. has a telephone quit line, and some have more than one. To find the options in your state, call 800-QUIT-NOW (800-784-8669).
- Individual or group counseling program. Your doctor may recommend local support groups or a treatment program where counseling is provided by a tobacco treatment specialist. Counseling helps you learn techniques for preparing to stop smoking and provides support for you during the process. Many hospitals, health care plans, health care providers and employers offer treatment programs or have tobacco treatment specialists who are certified to provide treatment for nicotine dependence. Nicotine Anonymous groups are available in many locations to provide support for smokers trying to quit. Some medical centers provide residential treatment programs — the most intensive treatment available.
- Internet-based programs. Several websites offer support and strategies for people who want to stop smoking. BecomeAnEX is free and provides information and techniques as well as blogs, community forums, ask the expert and many other features. Text messaging services, including personalized reminders about a quit-smoking plan, also may prove helpful.
Methods to avoid
There is no scientific evidence that these products work to help stop smoking and little is known about their safety.
- Products claiming to deter smoking. This includes products that change the taste of tobacco, special diets to curb nicotine cravings and vitamin combinations marketed as smoking cessation aids.
- Herbs and supplements. Homeopathic aids and herbal supplements are not regulated by the Food and Drug Administration (FDA), so they don't need to prove their effectiveness or safety.
- Nicotine lollipops and balms. Products containing nicotine salicylate are not approved by the FDA, and these products pose a risk for accidental use by children.
- Electronic cigarettes (e-cigarettes). Flavored mist containing nicotine that looks like smoke is puffed through a system that looks like a cigarette. Questions exist about the safety of e-cigarette vapor and the amount of nicotine provided.
- Hypnosis. Although no evidence supports the use of hypnosis in smoking cessation, some people say they find it helpful. If you choose to pursue hypnosis, talk to your doctor about finding a reputable hypnotherapist.
Tobacco in any form is not safe. This includes the use of:
- Dissolvable tobacco products. Tobacco pouches, lozenges, strips or other products contain small amounts of tobacco and nicotine you hold or dissolve in your mouth. These tobacco products are used by smokers in places where smoking is not allowed. There is no evidence they will help you stop smoking and little is known about their health effects.
- Smokeless tobacco and snuff (snus). These products contain nicotine in amounts similar to cigarettes and increase your risk of mouth and throat cancer, tooth and gum diseases, and other health problems.
- Pipes and cigars. These products have similar, though less frequent, health risks as cigarettes, and they are not a safe alternative.
- Hookahs (narghiles). These are water pipes that burn tobacco, and the smoke is inhaled through a hose. They are not safer than cigarettes. The water does not filter out toxins in the smoke, and the water and pipe have a risk of transmitting infections.
- Flavored cigarettes. Clove cigarettes (kreteks) and flavored cigarettes (bidis) carry the same health risks as smoking regular cigarettes and can cause additional health problems. Although they're not legal in the United States, they're still available in some countries.
