Nicotine Replacement Therapy For Smoking Cessation
According to this new study, using prescription drugs or over-the-counter products like gums, mints or patches won’t increase your chances of quitting smoking.
The US researchers followed two groups of people 2002/03 and 2010/11 and found at the end of the 12-month period, those using varenicline (sold in Australia as Champix), bupropion (Zyban), or nicotine-replacement therapy (gums, mints or patches) were no more likely to have quit smoking for 30 days or more than those who didn’t use these drugs.
Some have tried to dismiss earlier findings about the poor performance of nicotine-replacement therapy by emphasising “indication bias”. In the real world, those who opt to use medications to try to quit are likely to be more intractable smokers, more highly addicted to nicotine, and with histories of failure at quitting unaided. No one should therefore be surprised if they fail more often than those who try to quit on their own.
In this new study, this issue was anticipated and all smokers were assessed by what the study authors called a “propensity to quit” score. This score accounts for factors such as smoking intensity, nicotine dependence, their quitting history, self-efficacy to quit, and whether they lived in a smoke-free home where quitting would likely be more supported.
In the analysis, those who tried to quit with drugs and those who didn’t were matched on this propensity score, so “like with like” could be compared in the analysis. The findings held even when these “propensity” to quit factors were taken into account.
As for the evidence on e-cigarettes in quitting, neither the US Preventive Health Services Task Force, nor the UK’s National Institute for Health and Care Excellence or Australia’s National Health and Medical Research Council, have endorsed e-cigarettes as an effective way of quitting smoking.
Quitting smoking is the single most important thing anyone can do to reduce the likelihood they will get heart or lung disease, and a whole string of cancers.
It has been in the clear interests of the pharmaceutical and, more recently, the vaping (e-cigarette) industries, to promote the notion that anyone who tries to quit alone is the equivalent of someone with pneumonia refusing antibiotics. Hundreds of millions around the world have quit smoking without using any pharmaceutical intervention.
Before nicotine-replacement therapies became available in the 1980s, many millions of smokers successfully quit smoking without using any drug or nicotine substitute. The same still happens today: most ex-smokers quit by going cold turkey.
The problem is, in recent years, the government has moth-balled the national quit campaign, the megaphone for promoting this very positive message. Commercial interests are now com-modifying something millions have always done for themselves.
