How to Quit Smoking Confidently and Successfully
Joelle Thirsk Fathi, DNP, MN, BSN, ANP-BC, CTTS
Smoking cessation (quitting smoking) is one of the best things we can do to protect our bodies from disease, fight illness, undergo treatment, and help our bodies heal. Research shows that 70% of people who smoke want to quit 1 and that 41% of smokers have tried to quit for at least one day in the past year. There are many reasons why people want to quit smoking and better health is often at the top of the list.2 Unfortunately, many people who actively smoke have had many quit attempts that were unsuccessful; this can be discouraging and it can prevent people from trying to quit again. It can be difficult to know how to approach quitting smoking, find the support you need, and be successful in quitting for good. The content in this chapter will give you the key information you need to understand how nicotine dependence occurs, what happens when you stop nicotine, how to avoid the unpleasant symptoms of nicotine withdrawal, and most importantly, how to quit smoking safely and effectively.
Chemicals in Cigarettes
Cigarettes contain tobacco and up to 7,000 other ingredients, including many that are harmful to our health.3 When smoking a cigarette, toxic gases including carbon monoxide (which is poisonous) and chemicals, such as tar, are inhaled and build up in the blood.4These gases and chemicals are circulated throughout the body and cause damage to the body’s cells. Additionally, cigarettes contain nicotine. Nicotine is the notable ingredient that causes physical and mental dependence and makes it so hard to quit smoking.5
How Nicotine Affects the Brain
Nicotine is clever in how it works in the brain. It easily attaches to a receptor in the brain called the nicotinic acetylcholine receptor. Everyone has these receptors in the brain but for smokers, these receptors are activated by nicotine in a way that the non-smoker does not experience. When the nicotine attaches to the receptor, neurotransmitters (chemicals that your body makes) are released from that receptor. Dopamine is the most dominant neurotransmitter released when nicotine is consumed. This chemical stimulates the reward center in the brain and causes a pleasurable experience. Dopamine also enhances levels of energy and concentration, can elevate mood, and suppress appetite. The instant gratification and other positive side effects are all reasons why people continue to smoke. 5
Why Nicotine Withdrawal Happens
Identifying Nicotine Withdrawal Symptoms
Common symptoms of withdrawal include anxiety, irritability, agitation, and a drop in mood or even depression. People also experience disturbance in their sleep, difficulty with concentration, changes in bowel function, increased appetite, and urges to smoke.4 These symptoms are unpleasant and, if not prevented or treated, will cause a very strong urge to smoke again. Replenishing nicotine by having just one cigarette will ease or eliminate these symptoms and this is why people often go back to smoking, because it makes the symptoms of withdrawal go away, almost instantly.
When quitting smoking, staying away from cigarettes is the most important part of both short-term and long-term success in staying quit. There are methods of quitting smoking that are proven to minimize and even prevent the unpleasant and detrimental symptoms of withdrawal from nicotine.
What it Takes to Quit Successfully
People are able to quit on their own but it can be a challenge to do this alone. You will have much more success if you get support, counsel, and treatment from a health care professional or a specialist trained in how to quit smoking. Using nicotine replacement therapy and/or a prescription medication to quit at least doubles the chances of long-term success and in some cases even quadruples the chances of quitting for good.5-7
Options for Quitting Smoking: Nicotine and Non-Nicotine Therapy
Nicotine Replacement Therapy:
Nicotine replacement can be a very effective approach to quitting smoking because the body absorbs the nicotine in the blood stream and finds its way to the brain but toxic chemicals are not being inhaled in your lungs. When nicotine reaches the brain, it attaches to the nicotinic acetylcholine receptors and causes a release of dopamine. Nicotine replacement therapy mimics having a cigarette and delivers nicotine to the brain, preventing and treating withdrawal symptoms.5
The most important thing to remember when using nicotine replacement therapy is to be sure to get enough nicotine replacement; if not used properly, it will not work for you. Often people feel that the patch, gum, or lozenge did not work for them and this is usually because they were not getting enough replacement of nicotine to prevent symptoms of withdrawal. Getting enough nicotine with a combination of the long-acting patch and a short-acting method will make quitting smoking much easier and provide a smoother transition off cigarettes.
Transdermal Patch, A Long-Acting Nicotine Replacement
Nicotine replacement is available in a patch that delivers nicotine continuously over 24 hours.7 The patch is considered a long-acting delivery method because it sends a steady amount of nicotine through your skin to the blood, then the brain. It is important to dose the patch according to how many cigarettes are smoked in a day so that you get enough nicotine. A cigarette is equal to about 1mg of nicotine and the patch should be dosed 1mg for every cigarette smoked in a typical day. Choosing the right dosed patch will give an optimal delivery of nicotine to the brain and minimize or prevent withdrawal symptoms.6, 8, 9
Patch Dosing Recommendation 9
less than 10 cigarettes/day (less than 1/2 pack per day) 7mg patch
10 or more cigarettes/day (more than 1/2 pack per day) 14mg patch
20 cigarettes/day (1 pack per day) 21mg patch
More than 20 cigarettes/day Dose patch to the number of cigarettes smoked per day with the guidance of your health care provider
The patch should be changed every 24 hours. It is recommended to use the initial patch dose for one full month and then step down the patch doses every 2-4 weeks until off the lowest dose.
Example: if you start the regimen at 21 mg, use this dose every day for 4 weeks, then step down to a 14mg patch for 2-4 weeks, then step down to a 7mg patch for 2-4 weeks, and then stop.9
In this example, you would use a patch for a total of 8-12 weeks (2-3 months) after you quit smoking; this ensures a smooth landing in getting off nicotine safely and effectively. You should know that this is longer than many people think they need to use patches. Remember, the key is to be successful in the long run, so wean off as slowly as needed; there is no rush!
The patch is formulated as a long-acting medication. For safe, effective, and continual delivery of the medication; the patch should NOT be cut. Similar to cigarettes, the nicotine in the patch is stimulating and can cause active or vivid dreaming and/or wakefulness at bedtime. Unless you are accustomed to smoking in the middle of the night, it is recommended to take the patch off an hour before bedtime to avoid disruption of sleep.
Tips on Using the Patch
Start a new patch as soon as you wake up the next morning. Remember that it takes at least an hour for the nicotine in the new patch to deliver a steady state of nicotine in the blood stream so, it’s important to use a short acting nicotine replacement, in combination with the patch, for urges to smoke, as discussed next.
Short-acting Nicotine Replacement
Nicotine replacement is available in several forms of short-acting delivery methods. These short-acting doses of nicotine are very important in the success of using nicotine replacement therapy in quitting smoking. Even if you use the transdermal patch for continuous nicotine replacement, you may have urges to smoke and withdrawal symptoms. Think of short acting nicotine replacement as your quick acting, rescue, medication. Treating these cravings with one of the following four options of nicotine replacement, in combination with the long-acting patch, is one of the most effective ways to avoid lapsing or relapsing with a cigarette and returning to regular patterns of smoking.
The gum is available in 2mg and 4mg doses. It is important to know that the gum only works if it is absorbed through the mucosal lining of your mouth (between your gum and your cheek). The best way to use the gum is to chew it until there is a peppery/spicy, tingly sensation, then park it between the gum and cheek for 5 minutes. Then chew it again until there is another sensation (about a minute) and park it for 5 minutes. Continue about five cycles (approximately 30 minutes) of this chew for 1 minute and park for 5 minutes, in order to get all the dose of nicotine the gum has to offer. The chewing for a minute is necessary to activate more nicotine in the gum so you may then park it for optimal absorption. It is safe to chew up to 20 pieces of gum a day for breakthrough cravings and withdrawal symptoms. 6, 8, 9 Gum is not effective when wearing dentures but can be chewed and effective if the dentures are out of the mouth. This product is available over the counter for purchase. Many insurance companies are now covering this when prescribed by a medical provider.
Getting the Most out of the Gum
If the nicotine gum is chewed like a regular piece of chewing gum and you swallow the nicotine, you may experience nausea, indigestion, or hiccups; be sure to go through the chew and park cycle as discussed above in order to optimize absorption. If you swallow the nicotine, you will not absorb the nicotine because of the acid in the stomach. Also, avoid any drinking or eating, especially carbonated drinks and acidic foods and beverages, right before and during use of the nicotine gum because these will destroy the nicotine in the gum.9
The lozenge is similar to the nicotine gum. It is available in 2mg and 4mg doses and, like the nicotine gum, the lozenge needs to be tucked between the gum lining of the mouth and cheek to be absorbed. The standard starting dose is the 2mg lozenge, which delivers the equivalent of nicotine in one cigarette. Avoid acidic foods or beverages right before use and when a lozenge is in the mouth.6, 8, 9 This product is available for purchase over the counter. Many insurance companies are covering this when prescribed by a medical provider.
Nicotine Nasal Spray
The nasal spray contains nicotine that is delivered through the mucosal wall/tissue of the nose. When using it, it is important to tip the head back slightly and spray it against the nasal wall but do NOT sniff it deep into the sinuses. One spray in each nostril (2 sprays) delivers a similar dose of one cigarette.6, 8, 9 This product is available only by prescription. It is normal for this spray to cause a warm sensation in the nostrils.
The nicotine inhaler is a popular method of short-acting nicotine delivery for people who have a strong attachment to the ritual of holding and handling a cigarette. Although this is called an “inhaler”, the nicotine delivery is taken in by puffing on the inhaler, not taking a deep inhalation, or “drag”, as would be done with a cigarette. The nicotine is absorbed through the mucosal tissue of the mouth so it is important to only inhale or puff the medication into the mouth (not the lungs) for optimal absorption; 20 puffs = the amount of nicotine in one cigarette. This product is available only by prescription6, 8, 9 and is different from an eCigarette, which is discussed later in this chapter. Your pharmacist can teach you how to load and use the inhaler. This product is not effective if dentures are in place.
How to know if you are getting too Much Nicotine Replacement
It is possible to be taking too much nicotine replacement. Symptoms that could be associated with taking too much nicotine are: feeling anxious, jittery, headache, nausea, excessive wakefulness, and chest pain or heart palpitations. If you develop these symptoms or any others that you think are associated with nicotine delivery, stop using all nicotine products, including taking the patch off and call your medical provider for further advice, as soon as possible. Remember to avoid smoking cigarettes while using the nicotine replacement therapy to reduce the chances of overdosing on nicotine and provide the best opportunity to quit.
Long acting nicotine patch + Short acting nicotine (gum, lozenge, inhaler, or spray) = Successful Long-term Quit
Non-Nicotine/Prescription Medication Therapy Options
Bupropion SR is a long acting prescription medication that is commonly used to help people quit smoking. It has shown to double the success rates in quitting smoking and works well with the nicotine replacement therapies. It is also known as “Zyban” and “Wellbutrin”.
Some people are hesitant to take this medication because they have heard that it is used for depression and do not want to take an “antidepressant”. It is true; bupropion is used for depression because it allows more of the neurotransmitters, dopamine and norepinephrine, to circulate in the brain.
Remember that nicotine drives the dopamine levels up and this is why the brain experiences a mood elevation when smoking. When the dopamine levels drop with the withdrawal of nicotine, the brain can experience agitation, anxiety, and depressive mood changes. Bupropion helps in transitioning off cigarettes/nicotine because it allows more dopamine to circulate and protects the brain from an abrupt withdrawal off the dopamine. It reduces the craving for cigarettes, helps with the anxiety of quitting smoking, and often suppresses appetite and controls weight gain associated with quitting smoking.4-6, 9 Talk to your health care provider to determine if bupropion is the right medication for you.
Varenicline is a prescription medication that is commonly used to help people quit smoking. Varenicline has shown an increased success rate in quitting smoking of up to four fold.9 It is also known as “Chantix”.
This medication works by attaching to the nicotinic acetylcholine receptors in the brain and causes the same release of dopamine that nicotine does. This medication mimics the presence and action of nicotine and tricks the brain into thinking it has nicotine on board. 4-6, 9Because of the way this medication mimics the presence of nicotine and attaches to the nicotinic acetylcholine receptors in the brain, in most cases, you would not benefit from using nicotine replacement therapies; Varenicline is typically used alone.
This medication reduces the craving for nicotine and reduces withdrawal symptoms. Some people are hesitant to take this medication because they have heard of potential side effects including nausea, vivid dreams, or mood changes. Talk to your health care provider to determine if Varenicline is the right medication for you.
Tips on Taking Bupropion SR and Varenicline
Always take these medications with food to avoid nausea. If you are taking these medications twice a day, be sure to take the second dose closer to dinner time to avoid disruption of sleep and vivid dreams. Like nicotine from cigarettes, Varenicline stimulates the central nervous system and because of this action, it is more activating than sedating; taking it with dinner is ideal. Sometimes a dose adjustment needs to be made in order to tolerate the medication and optimize your opportunity to quit smoking.
Wellbutrin is also more activating then sedating. If you experience agitation or even anxiety that does not go away, it might mean you need to reduce the dose of the medication or even stop it. Cutting back on the dose may reduce these symptoms and allow you to benefit from its action in helping you quit.
If you experience any unpleasant symptoms, while trying to quit smoking, including disturbing thoughts or changes in your mood, you should stop the medication immediately and call your medical provider.
In-Person Counseling and Quitting Smoking
Alternative Approaches to Quitting
The quit line specific to any state in the U.S. or any of the Canadian provinces can be located by calling the North American Quitline Consortium (NAQC) at 1-800-QUIT-NOW or by visiting their website at www.naquitline.org . You can also find out about local resources through your local public health department or by searching online using your specific state or city and “quit smoking” as keywords.
Many employers, especially large employers, have contracts with a professional quit line service that employees, and even family members of employees, can benefit from. The services and resources they provide are similar to the public quit lines. Call your employer’s Human Resources department to see if they provide this benefit.
