A public health history of the tobacco epidemic
1940s +50s
1960s + 70s
1980s
1990s
2000-
- new scientific evidence drives increase in research on tobacco & disease
- development of government health policy; - industry scientists lose power to marketing executives
- companies expand international activities; - use ‘product modification’ policy as hostage to keep
advertising
- litigation, particularly in the USA; - Minnesota case releases >30 million documents; - health advocacy increases
- ‘We’ve changed!’ programmes, e.g. BAT’s ‘Social reports’; - WHO’S FCTC process: tobacco on health agenda worldwide; - tobacco companies try to ‘help’ with FCTC laws, while exploiting & expanding markets as fast as possible- World Trade Organisation continues pressure to open markets
FCTC: what governments must do• comprehensive ban: advertising, promotion & sponsorship• protect public from smoke in public places, incl. workplaces• health warnings: +/< 30% of main pack area• ban deceptive pack terms - ‘light’, ‘low tar’, etc • tackle smuggling• tax increases • tobacco regulation• manufacturers to disclose ingredients • legal action encouraged • promote funding for global tobacco control• have national mechanism for tobacco control• include cessation services in health programmes• no distribution of free tobacco products• promote NGO action• ban underage tobacco sales• no opting out of any FCTC provisions!

Tobacco cessation:
- helping people to stop smoking,in the clinical setting
Smoking cessation
• Doctors have unique ability to help smokers to stop smoking
• Many smokers want to stop smoking, & others may be receptive to encouragement to stop
• A brief intervention by the doctor increases chances that a smoker will successfully stop smoking
• Nicotine replacement therapy (NRT) and other pharmaceuticals can increase the success rate of more dependent smokers
Deciding to try to stop
Trying to stop
Stopping
Relapsing
Thinking about stopping
“Contented Smokers”
Never smoking again!
The process of stopping smoking
The brief intervention
• Offer information, advice, & encouragement to get the patient to consider making a firm commitment to quit
• Reinforce the decision to quit• Give the patient a cessation leaflet, if available• If appropriate, offer to prescribe NRT & give advice• Advise patient to plan a quit day in advance• At the end, reinforce patient’s decision to quit &
offer further help

Cochrane Database Syst Rev. 2007 Jan24;(1):CD000031 • 17 new trials identified since last update (2004); total = 53
(40 bupropion + 8 nortriptyline)• When used as sole pharmacotherapy, bupropion (31 trials)
& nortriptyline (4 trials) both doubled odds of cessation. • Insufficient evidence that adding bupropion or nortriptyline
to NRT provides additional long-term benefit • 3 trials of extended therapy with bupropion to prevent
relapse after initial cessation found no evidence of significant long-term benefit
• From available data, bupropion & nortriptyline appear to be equally effective & of similar efficacy to NRT
• Pooling 3 trials comparing bupropion to varenicline showed a lower odds of quitting with bupropion (OR 0.60, 95% CI 0.46 to 0.78).
• (There is a risk of about 1 in 1000 of seizures associated with bupropion)
