Chronic obstructive pulmonary disease (COPD) is a complex multi variable disease, with raged inflammation triggered mainly by cigarette smoke; regardless of sustained quitting approximately 15% of the ex-smokers develop severe emphysema and COPD.
However, some earlier studies [ 3, 26] classified people who had quit smoking for approximately 2 to 5 years or more under the nonsmokers group.
In NSW, the most common aid used in quit attempts is NRT (approximately 33%), followed by bupropion (13.2%), with very small proportions of smokers reporting that they used behavioural aids such as telephone helplines [ 4, 8].
4, 9 Clinical trials have demonstrated the ability of bupropion to approximately double the successful quit rate compared to no therapy.
Approximately 75% of aided quit attempts (Ferguson, Bauld, Chesterman, & Judge, 2005) and 95% of unaided quit attempts fail within a year (Hughes, Keely, & Naud, 2004) with relapse being highest early on, typically in the first few weeks of abstinence (Hughes et al., 2004).
Cessation advisors come into contact with approximately 500,000 UK smokers attempting to quit each year (using Stop Smoking Services), probably resulting in about 13,000 smokers who permanently quit [ 4].
