Smoking Cessation

Smoking Cessation

Also indexed as: Quitting Smoking

Illustration

Support is readily available to help you stop smoking and stay smoke-free for life. According to research or other evidence, the following self-care steps may be helpful:

What you need to know

  • Try nicotine substitutes
  • For some extra support, try over-the-counter nicotine gum (Nicorette), lozenges (Commit), or patches (NicoDerm CQ, Nicotrol)
  • Focus on physical fitness
  • Increase your physical activity after giving up tobacco to prevent weight gain
  • Participate in a program
  • Find a smoking-cessation program that holds regular meetings to discuss important topics such as strategies for stopping; factors that increase relapse risk; and problem-solving, stress-reduction, and coping skills
  • Ease the craving with a doctor’s help
  • Ask your healthcare provider about bupropion (Zyban, Wellbutrin) to conquer cravings, and buspirone (Buspar), lorazepam (Ativan), or alprazolam (Xanax) to help reduce withdrawal anxiety; also ask about taking tryptophane in combination with a high-carbohydrate diet, which can raise serotonin levels and control tobacco cravings

These recommendations are not comprehensive and are not intended to replace the advice of your doctor or pharmacist. Continue reading the full smoking cessation article for more in-depth, fully-referenced information on medicines, vitamins, herbs, and dietary and lifestyle changes that may be helpful.

About Smoking Cessation

While cigarette smoking is declining in many Western countries, more than 20% of US adults continue to smoke.1 However, studies show that 70% of them would like to quit.2 3 In many countries, major public health efforts are in place to encourage smokers to quit.4 5 Since many attempts to quit smoking are not permanent, it may be important to take advantage of a variety of strategies to increase the chances of success.6 7

What are the symptoms?

Smoking cessation can result in improved health, including reduced risk of heart and lung diseases, many cancers, pregnancy complications, and other health problems. Soon after quitting, most smokers notice that coughing declines and that ordinary activities no longer result in shortness of breath. Also, smokers find that their teeth stain less easily, their breath is fresher, and food tastes better as their senses of taste and smell return to normal. However, smoking cessation can lead to short-term symptoms such as irritability, depression, difficulty sleeping or concentrating, headaches, and fatigue, due to the physical effects of nicotine withdrawal and the psychological effects of giving up a habit. Quitting smoking often leads to weight gain as well.

Dietary changes that may be helpful

A high-carbohydrate diet, combined with a tryptophan supplement (50 mg per 2.2 pounds of body weight per day) lessened withdrawal symptoms and helped participants smoke fewer cigarettes in one controlled study,8 but no research has investigated the effect of dietary changes alone on smoking cessation.

Top

Lifestyle changes that may be helpful

Smoking cessation often leads to weight gain, which can dissuade smokers from trying to quit or cause them to resume smoking.9 10 Increasing physical activity after quitting smoking can minimize weight gain, and a controlled trial found that adding exercise to a smoking cessation behavioral counseling program improved abstinence rates.11 12 However, other, smaller studies have not shown that exercise either alone or added to a comprehensive program helps to maintain abstinence.13 14 Adding weight control through dieting to smoking-cessation programs has resulted in either an increase in smoking relapses or no effect.15 16 Changing the diet at the same time as quitting smoking may require more discipline than most people can achieve.

Other therapies

Individuals who want to quit smoking cigarettes will have better success if they decide on a quit date and change their routines around typical smoking cues, such as coffee breaks, meals, boredom, and sexual activity. Absolute stopping, known as quitting “cold turkey,” is generally considered a better method than weaning off.

Vitamins that may be helpful

Nicotine addiction is thought to be caused by increased stimulation of nerve receptors for various brain chemicals, including serotonin.17 Withdrawal symptoms that accompany smoking cessation could be related to the sudden drop in nerve receptor stimulation. However, a double-blind study found that depleting blood levels of tryptophan, the precursor to serotonin, had no effect on withdrawal symptoms after five hours of smoking abstinence.18 In a controlled study, a daily tryptophan supplement (50 mg per 2.2 pounds of body weight) along with a high-carbohydrate diet (which increases brain uptake of tryptophan) was added to a smoking-cessation program. While rates of complete abstinence were not significantly affected, tryptophan plus a high-carbohydrate diet lessened withdrawal symptoms and helped participants smoke fewer cigarettes.19 More research is needed to clarify whether supplementing with tryptophan or other serotonin precursors might help support smoking cessation.

Herbs that may be helpful

Lobelia (Lobelia inflata), also known as Indian tobacco, contains a substance (lobeline) that has some effects on the nervous system that are similar to the effects of nicotine, and preliminary reports suggested that pure lobeline or lobelia herb could be used to support smoking cessation.20 21 22 However, results in preliminary human trials with lobeline have been mixed and generally negative, and no long-term controlled studies of lobeline or lobelia for smoking cessation have been done.23 24

Other herbs used to treat anxiety are sometimes recommended as part of a smoking cessation program, including oat straw (Avena sativa), scullcap (Scutellaria lateriflora), valerian (Valeriana officinalis), lemon balm (Melissa officinalis), and vervain (Verbena officinalis). Of these herbs, only oat straw has been investigated in human research for smoking cessation. At least three trials have reported no effect of oat straw on smoking cessation, but one controlled study in India found that taking 1 ml of an alcohol extract of oat straw four times per day significantly reduced the number of cigarettes smoked per day.25 26 27 28

Holistic approaches that may be helpful

In the year 2000, the United States Public Health Service published updated smoking-cessation guidelines for doctors.29 This report identified counseling and behavioral therapies as proven effective components of a smoking-cessation program. Effective components include providing basic information about successful quitting, identifying factors that will increase the risk of relapse, and teaching problem-solving and coping skills. Also effective is social support provided either in a healthcare setting (for example, being able to talk about the quitting process with a doctor) or by strategies that teach the quitter to build a support network among friends, family, and the community. Guidelines issued in other countries have reached similar conclusions about the effectiveness of counseling and behavioral therapies.30 Government-sponsored, free counseling resources in North America include Quitline [800-QUIT-NOW] and SmokeFree (www.smokefree.gov). Group or individual counseling is often a component of successful smoking cessation programs offered in schools and the workplace.31 32

People tend to smoke more often under conditions of stress. Those who achieve long-term success in quitting smoking have been shown to have more social support and less stress than people who eventually relapse.33 Stress-reduction techniques that have been shown in controlled trials to be effective for assisting smoking cessation include self-massage, guided relaxation imagery, and exercise.34 35 36

Some research indicates that the effectiveness of acupuncture on abstinence from smoking is similar to that reported for nicotine chewing gum and behavioral therapy, and that these methods can complement each other.37 One controlled trial showed that daily cigarette consumption decreased more significantly during acupuncture treatment to points associated with smoking cessation than in fake acupuncture treatment (i.e., acupuncture applied to points not associated with smoking cessation). Altogether, 31% of subjects in the treatment group had quit smoking completely at the end of the treatment, compared with none in the control group.38 Electroacupuncture treatment to points on the ear has also been shown to aid in smoking cessation compared with fake ear acupuncture in a controlled trial.39 However, most clinical trials have not achieved comparable results. An analysis of 22 studies found that while acupuncture is often as effective as other smoking cessation techniques, its effectiveness does not last very long. Moreover, in most studies the overall effect of real acupuncture was no better on average than fake acupuncture for smoking cessation.40

A controlled clinical trial showed that people undergoing single hypnosis sessions smoked significantly fewer cigarettes and had a higher frequency of abstinence than a placebo control group.41 However, most clinical trials have not corroborated these results.42 A review of 59 studies of hypnosis and smoking cessation concluded that hypnosis “cannot be considered a specific and efficacious treatment for smoking cessation.”43
