Strategies to Help Patients Break the Chains of Tobacco Addiction: Evidence-Based Treatments Can Help Patients Quit despite Psychiatric Illness
Heffner, Jaimee L., Anthenelli, Robert M., Current Psychiatry
You are treating Mr. P, age 34, for schizoaffective disorder. He smokes 1 pack of cigarettes per day and has smoked for approximately 17 years. He has tried to stop but never has been able to quit for more than a few weeks. He reveals whenever he tries to quit, he starts feeling extremely lethargic and "depressed" and resumes smoking to prevent these symptoms from worsening. However, Mr. P expresses some interest in trying to quit again and asks whether any medications could prevent him from becoming depressed while he tries to quit
Cigarette smoking is overrepresented and undertreated among individuals with psychiatric illness, in part because of the largely unfounded belief held by some patients and clinicians that smoking cessation might worsen psychiatric symptoms. In this article, we argue this challenge can be overcome and psychiatrists and other mental health professionals can and should help their patients reap the innumerable benefits of quitting smoking. We discuss:
* the short-and long-term effects of smoking cessation
* evidence-based treatment guidelines for working with motivated and unmotivated smokers
* unique issues that may arise when treating smokers who have psychiatric disorders.
Quitting: Profound benefits
Quitting smoking has substantial benefits beginning within minutes after taking the last puff. Some of the benefits that occur within the first few days of quitting include:
* decreased blood pressure and pulse rate
* improved circulation
* improved ability to smell and taste
* easier breathing.
Longer-term smoking abstinence drastically reduces risk of heart attack, stroke, cancer, respiratory disease, and a host of other illnesses that affect--and kill--individuals with psychiatric disorders several decades earlier than their counterparts in the general population. (1) There also are financial benefits to quitting; using the 2009 national average of $5.33 per pack, a 1-pack-per-day smoker who quits would save > $150 per month, which accounts for only the direct cost of cigarettes. (2)
Although the beneficial effects of quitting smoking are profound and far-reaching, in the short-term they are counterbalanced by nicotine withdrawal symptoms--including restlessness, irritability, depressed mood, concentration problems, and increased appetite/weight gain--that are formidable distractions from the positive aspects of quitting. Additionally nicotine withdrawal symptoms tend to be more severe in smokers who have a psychiatric disorder. (3) Fortunately, there are effective, evidence-based methods of reducing withdrawal symptoms and helping smokers cope with these and other challenges of quitting.
Combined treatment is best
Current treatment guidelines (4) suggest all smokers should be offered pharmacotherapy and counseling to aid quitting because this combined approach has the highest success rate (Algorithm). Table 1 (page 44) (4) provides information about dosing, efficacy, and side effect profile of each of the 7 FDA-approved medications for smoking cessation. Using any of the approved medications at least doubles the odds of successful quitting compared with placebo. (4) These pharmacotherapies can reduce or prevent nicotine withdrawal symptoms and--at least in the case of bupropion and varenicline--decrease reinforcement from smoking, thereby lowering the likelihood a lapse (ie, smoking [greater than or equal to] 1 cigarettes without returning to regular smoking) will develop into a full-blown relapse (ie, return to regular smoking).
