Hurt, Mayo Nicotine Dependence Center Used By Permission

  6. 13.2-14.5 years of life lost due to smoking

  7. Smoking Causes Death Smoking causes approximately • 90% of all lung cancerdeaths in men • 80% of all lung cancerdeaths in women • 90% of deaths from chronic obstructive lung disease (COPD) CDC

  8. Smoking Causes Death Compared with nonsmokers smoking increases risk of— • Coronary heart disease by 2 to 4 times • Stroke by 2 to 4 times • Men developing lung cancer by 23 times • Women developing lung cancer by 13 times • Dying from chronic obstructive lung diseases (COPD) by 12 to 13 times CDC

  9. Tobacco Use in North Dakota • ~116,000 ND adults and ~8,000* HS students smoke cigarettes • ~20,000 ND adults and ~3,800^ HS students use spit tobacco -HS students: *26% in 2003, 27% in 2005, 22% in 2007 ^10% in 2003, 12.7% in 2005, 10.2% in 2007 (BRFSS 2008) (YRBS 2005,2007)

  12. Tobacco Use in North Dakota • Native American population: 49.3% adults use tobacco (highest smoking rate of any ethnic group in U.S.) • Smoking in pregnancy higher in North Dakota than national average: 18% vs. 12% • WIC Clinic population survey: 45% smoked prior to pregnancy vs. 16% non-WIC

  13. Tobacco Use in North Dakota -Between 2001 and 2008, Adult smoking rates in North Dakota dropped from 23.2% to 18.1%, similar to national trends -Healthy People 2010 Goal (Now): 12% or less -52% report cessation attempts annually Behavioral Risk Factor Surveillance System (BFRSS)

  14. Tobacco’s Health Cost inNorth Dakota • Smoking-attributable direct medical expenditures: $250,000,000 • Smoking-attributable productivity costs: $192,000,000 • Medicaid expenditures for smoking-related illnesses and diseases: $47,000,000 Annual Costs! CDC. Smoking-Attributable Mortality, Morbidity and Economic Costs (SAMMEC) report, 2008. CDC Data Highlights, 2006.

  15. North Dakota spends $691 per capita on direct medical expenditures andlost productivity due to smoking

  16. Tobacco Use in North Dakota • Heart Disease and Cancer are the leading causes of death in North Dakota • Tobacco use is the leading preventable cause of death

  17. Secondhand Smoke Deaths United States • Lung cancer – 3,000 deaths annually • Ischemic heart disease – 35,000 deaths annually North Dakota • 80-140 deaths annually

  18. Tobacco and Cardiovascular Disease(Heart Disease and Stroke)

  19. Coronary Heart Disease • Leading cause of death in the USA • Smoking attributable mortality 30% • Most of decline in incidence is because of  smoking rate • ~100,000 CVD deaths due to smoking and >35% occur before age 65 • 2-6X  risk of sudden death in smokers • Over 1.6 million coronary procedures/year American Heart Association Report of the U.S. Surgeon General 2004

  20. Cerebrovascular Disease-Stroke • 600,000 cases/year in U.S. • 30 % fatality rate at one year • Similar risk factors as Coronary Heart Disease

  21. Smoking and Cardiovascular Disease • Quitting smoking will lower risk substantially in about 5 years • Smokers with established CVD lower risk of subsequent events by quitting smoking

  22. Tobacco and Cancer

  23. U.S. 1997-2001 MMWRJuly 1, 2005 / 54(25);625-628 US Surgeon Generals Report 2004

  25. Lung Cancer • Leading cause of cancer death in men and women • Smoking causes 87% of lung cancers in the USA • Smoking increases risks of all four major types of lung cancer • Cigar and pipe smoking associated with increased risk • 5-year survival for lung cancer 15% • Reduced risk with smoking cessation • Average 2 year cost per patient - $48,000 MMWR, ACS

  26. Relative risk of lung cancer mortality Years post smoking cessation American Cancer Society

  27. Tobacco Use and Oral Cancers • ACS - 28,900 cases & 7,400 deaths annually • 90% are Squamous Cell Carcinoma (SCC) • Worldwide - 300,000 cases annually • Ranks 6th among all cancers • 3rd most common site in males in developing countries Vokes EE, NEJM 1993 • Tobacco causes of >85% oral cancer deaths in males Johnson N, J Dent Educ 2001 • High rate of morbidity & mortality • 5-yr average survival < 50%

  28. COPD and Smoking • 4th leading cause of death • Accounts for > 100,000 deaths/yr • Symptomatic improvement and lung function preservation with tobacco cessation Report of the U.S. Surgeon General 2004 American Lung Association

  29. Tobacco Cessation Improves Surgical Outcomes • Cardiovascular complications • Respiratory complications • Wound-related complications • Many elective procedures require tobacco cessation

  30. Special Populations

  31. Pregnancy and Tobacco Use • Fourfold increase in small for gestational age; Increased prematurity • Twice the rate of spontaneous abortions • Increased risk of abruptio placentae, placenta previa, premature and prolonged rupture of membranes Russell, T, et al Nicotine & Tobacco Research, Vol6, Supp 2. Apr. 2004 Gabbe: Obstetrics 4th ed 2002 Pediatrics 2005; 116: 462-467

  32. Pregnancy and Tobacco Use • Intrauterine growth restriction • Positive association between smoking and sudden infant death syndrome (SIDS) and increased respiratory illnesses in children Russell, T, et al Nicotine & Tobacco Research, Vol6, Supp 2. Apr. 2004 Gabbe: Obstetrics 4th ed 2002 Pediatrics 2005; 116: 462-467 • Possible Association with maternal smoking and ADHD Am J Psych 2003 Jun;160(6):1028-40

  33. Pregnancy and Tobacco Cessation • Medications controversial • NRT Category D • Weigh risk vs. benefit • Counseling is a key component, possibly low dose intermittent NRT (gum, lozenge)

  34. North Dakota Providers:Do you offer tobacco cessation options to pregnant patients? 2009 Unpublished, NORTHSTAR,UNDSMHS Dept Family and Community Medicine

  35. North Dakota Providers: What types of counseling do you offer pregnant patients for tobacco cessation? 2009 Unpublished, NORTHSTAR,UNDSMHS Dept Family and Community Medicine

  36. Smoking and Diabetes • Strong Association between smoking history and development of Type 2 Diabetes • Now thought to be an independent risk factor, like obesity • Several large studies to date with more recent interest • Already a high risk CVD population • Glucose control may be worse

  37. Tobacco Use and Mental Illness • Tobacco use in patients with a psychiatric diagnosis ~41% • Tobacco use patients without a psychiatric diagnosis ~20% Lasser, et al JAMA 2000

  38. Smoking in the Chemically Dependent Population • Smoking rate in the general population ~20% • Smoking rate in the chemically dependent population ~80+% • Smoking is more deadly to chemically dependent population: 4 times the death rate of non-smokers 51% of deaths from tobacco 33% of deaths from drugs or alcohol CDC 2005; Walsh, etal Drug & Alcohol Review (24) 2005; Hurt, et al Alcoholism: Clin & Exp Res (18) 1994

  39. Smoking Cessation in Mental Illness and Chemical Dependency • Nicotine Replacement Therapy may be best choice • Other medications (buproprion, varenicline) have psychiatric effects that should be considered

  40. Tobacco Cessation

  41. Nicotine is addictive…and this is precisely why it is there • The cigarette is a highly engineered nicotine delivery device • Chemicals like ammonia are added to release more nicotine • Nicotine is there on purpose, for a purpose • Nicotine is not a carcinogen (patients may not know this)

  42. Pharmacotherapy(Medications)For Tobacco Cessation

  43. Nicotine Withdrawal • Symptoms -anger/irritability -depression/anxiety -insomnia -increased dream activity • Peak in 1st week, last 2-4 weeks • ~50% experience significant withdrawal symptoms • Most patients underestimate withdrawal symptoms Hughes Nic Tob Res 2007 Madden Addiction 1997 Stages J Clin Psych 1996

  44. Pharmacotherapy • Nicotine replacement therapy (NRT) • Gum • Patch • Spray • Inhaler • Lozenge • Bupropion (Zyban, Wellbutrin) • Varenicline (Chantix) • Other medications in development

  45. Nicotine replacement therapy • Replace the nicotine supplied by cigarettes • Conversion: Each cigarette provides 1 mg of nicotine • Combination therapy • Most people underdose NRT, or don’t take it long enough

  46. Nicotine Replacement Therapy (NRT) • 1mg for each cigarette smoked • 10 cigs=10mg • 20 cigs=20mg • 40 cigs=40mg • Note: may exceed label recommendations

  47. Bupropion • Inhibits reuptake of dopamine & norepinephrine • Exact mechanism of action in smoking cessation is not clear • Initially developed as an antidepressant • Promotes smoking cessation even in the absence of depression

  48. Varenicline(Chantix) • A partial nicotine receptor antagonist • Binds to the nicotine receptors in the brain • “Feeds the need” for nicotine at the CNS level • Essentially a “form of NRT”

  49. Varenicline • Most common side effects - nausea (16-30%) - insomnia (18-19%) - abnormal dreams (9-13%) • Weight-neutral • New FDA warning-monitor for changes in mood/mental status/behavior
