9 Special special concerns of smoking and smoking cessation in the setting of psychiatric disease

10 Adults with Mental Illness or Substance Use Disorder Account for 40% of All Cigarettes Smoked 1 1 Substance Abuse and Mental Health Services Administration, Center for Behavioral Health Statistics and Quality (Feb. 5, 2013) The NSDUH Report: Smoking and mental illness. Rockville, MD

11 Myths of Smoking Cessation in Psychiatric Disease The patients are not interested in quitting. They cannot quit. Quitting interferes with recovery from mental illness or addictions. Tobacco is not as harmful as other substances. Tobacco is necessary for self-medication and tobacco cessation would be too stressful. Tobacco cessation efforts might prevent treatment of other addictions. CDC Best Practices User Guide:Health Equity in Tobacco Prevention and Control 2015 Prochaska JJ NEJM 2011;365:

14 Change in mental health after smoking cessation: systematic review and meta-analysis

15 Difference between change in mental health outcomes (anxiety, mixed anxiety and depression, depression, stress) from baseline to longest follow-up in people who stopped smoking or continued to smoke. Gemma Taylor et al. BMJ 2014;348:bmj.g1151

16 Difference between change in mental health outcomes (positive affect, psychological quality of life) from baseline to longest follow-up in people who stopped smoking or continued to smoke. Gemma Taylor et al. BMJ 2014;348:bmj.g1151

17 Conclusions Smoking cessation is associated with reduced depression, anxiety, and stress and improved positive mood and quality of life compared with continuing to smoke. The effect size seems as large for those with psychiatric disorders as those without. The effect sizes are equal or larger than those of antidepressant treatment for mood and anxiety disorders

18 Varinecline, Bruproprion and Nicotine Drug Interactions Buproprion Nicotine hypertension Many DDI importantly promoting seizure activity Nicotine Buproprion hypertension (6% vs 3.1% placebo) Varinecline -partial nicotinic agonist selective for α4β2 nicotinic acetylcholine receptor subtypes DDI abacavir / dolutegravir / lamivudine, dolutegravir, ethanol, nicotine, ranolazine, vandetanib, insulin, coumadin, theophylline Repeal of FDA Warning The first study included 14,131 Chantix users and an equal number of NRT users. Sixteen psychiatric hospitalizations occurred among Chantix-treated patients, and 21 occurred among NRT patients (hazard ratio [HR], 0.76). The second study compared the acute (30-day) rates of hospitalizations for neuropsychiatric adverse events among new users of Chantix (n = 19,933) or the NRT patch (n = 15,867) who started therapy from August 2006 to August 2007 in the Military Health System. Similar to the previous study, 18 psychiatric hospitalizations occurred among Chantix users, and 16 occurred among NRT users (HR, 1.13).

20 Smoking Cessation

21 Facts About Smoking Cessation Approximately 46 percent of active smokers try to quit each year. Most try to quit cold turkey. Of those, only about 5 percent succeed. Most smokers make several quit attempts before they successfully quit for good.

22 US Smoking Cessation Trends

23 PHS Model for Treating Tobacco Use and Dependence General population Patient presents to a health care setting (clinic, hospital, work site, others) Relapse Ask screen all patients for tobacco use Chapter 2 Current users Advise to Quit Chapter 3A Assess willingness to quit Chapter 3A Yes Assist with quitting Chapter 3A Chapter 4 Arrange followup Chapter 3A Never users Primary prevention Former users No Promote motivation to quit Chapter 3B Patient now willing to quit Abstinent Prevent relapse Chapter 3C Patient remains unwilling US Public Health Service 2009

24 Patients Not Ready To Make A Quit Attempt Now (The 5 R s ) Relevance Encourage the patient to indicate why quitting is personally relevant. Risks Ask the patient to identify potential negative consequences of tobacco use. Rewards Ask the patient to identify potential benefits of stopping tobacco use. Roadblocks Ask the patient to identify barriers or impediments to quitting. Repetition The motivational intervention should be repeated every time an unmotivated patient has an interaction with a clinician. Tobacco users who have failed in previous quit attempts should be told that most people make repeated quit attempts before they are successful.

25 Smith et al. BMC Public Health (2017) 17:430 Smokers Perspective - Process

26 Developing a Plan for Smoking Cessation Among Patients Motivated to Quit STAR Set a quit date. Ideally, the quit date should be within 2 weeks. Tell family, friends, and coworkers about quitting, and request understanding and support. Anticipate challenges to the upcoming quit attempt, particularly during the critical first few weeks. These include nicotine withdrawal symptoms. Remove tobacco products from your environment. Prior to quitting, avoid smoking in places where you spend a lot of time (e.g., work, home, car). Make your home smoke-free. Tobacco Use and Dependence Guideline Panel. Rockville (MD): US Department of Health and Human Services; 2008 May.

27 Pharmacologic Therapy for Smoking Cessation: How Do We Pick? Approved Agents First-Line Long Acting (Patch) + Short Acting Lozenge, gum, inhaler, nasal spray Buproprion Second Line Buroprion + Combination NRT Varinecline + Combination NRT Third Line Buroprion + Varinecline + Combination NRT Nortriptyline Clonidine Experimental Approaches Anti-nicotine vaccines Naltrexone Cytisine

36 USPTF Guidelines on Counselling and Smoking Cessation Intensity/Frequency Both minimal (<20 min in 1 visit) and intensive ( 20 min plus >1 follow-up visit) physician-advice interventions effectively increase the proportion of adults who successfully quit smoking and remain abstinent for 6 mo. There is a dose response relationship between the intensity of counseling and cessation rates (i.e., more or longer sessions improve cessation rates). Multiple sessions should be provided; according to the Public Health Service guidelines, patients should receive 4 in-person counseling sessions. Cessation rates may plateau after 90 min of total counseling contact time. Duration Brief, in-person behavioral counseling sessions (<10 min) effectively increase the proportion of adults who successfully quit smoking and remain abstinent for 1 y. Although less effective than longer interventions, even minimal interventions (<3 min) have been found to increase cessation rates in some studies.

39 Use of ENDS Electronic Nicotine Delivery Systems (VAPING) and Smoking Cessation

40 The USPSTF concludes that the current evidence on the use of ENDS for conventional smoking cessation is insufficient. Evidence is lacking and conflicting, and the balance of benefits and harms cannot be determined. Given the established safety and effectiveness of behavioral and pharmacotherapy interventions, the USPSTF recommends that primary care providers direct patients who smoke to these other interventions.
