Goals • The U.S. Public Health Service has set goals to reduce smoking in our country by the year 2010. • First goal: • cut smoking rates among high school aged youth from 22% to 16%. • cut smoking rates among all adults from 23% to 12%. • Another goal: • increase the number of 1° care providers who routinely provide smoking cessation counseling for their patients who smoke by 75% • If these goals are met ~ 7.1 million early deaths will be prevented after 2010 !!!
Addictive Nature of Nicotine • Addictive characteristics of nicotine are a result of its action on the nicotinic acetylcholine receptors • nicotine reaches the brain within 10 seconds upon inhalation • Nicotine is known for its ability to both stimulate and depress the CNS • small rapid doses produce alertness and arousal • long drawn out doses induce relaxation and sedation • Tobacco use is more likely to lead to dependence than any other drug • Among those who ever tried one cigarette, approximately 1/3rd develop nicotine dependence • Similar to addiction associated with cocaine, amphetamines and opiates, nicotine addiction is a “chronic relapsing medical condition” that warrants clinical intervention.
Clinical Intervention for Smoking Cessation • Smoking cessation is the most important, cost effective preventive clinical intervention that healthcare providers can offer to their patients that smoke. • At least 70% of smokers see their primary care clinician annually which means that many practitioners are missing a prime opportunity to improve the health of their smoking patients • Primary care providers play a KEY role in the identification, assessment and treatment of smokers. • It is essential for smoking cessation to be implemented into the clinical setting during each patient visit!
