Nicotine replacement therapies 'not helping smokers quit long term'

FOR DAILY , COIMBATORE MAY 31: Tobacco-free cigarettes, beedis, nicotine patch and chewing gums on display at the Tobacco Cessation Clinic that was opened at Sri Ramakrishna Insitute of Oncology and Research in the city on Monday. These will be used to wean tobacco users from the habit.  

A new study has found that nicotine replacement therapies (NRTs), specifically nicotine patches and nicotine gum, is no more effective in helping smokers quit long-term, even when combined with smoking cessation counselling.

So, study’s researchers at Harvard School of Public Health (HSPH) and the University of Massachusetts Boston have called for better medications.

"What this study shows is the need for the Food and Drug Administration, which oversees regulation of both medications to help smokers quit and tobacco products, to approve only medications that have been proven to be effective in helping smokers quit in the long-term and to lower nicotine in order to reduce the addictiveness of cigarettes,” said co-author Gregory Connolly, director of the Centre for Global Tobacco Control at HSPH.

For the study, the researchers followed 787 adult smokers in Massachusetts who had recently quit smoking. The participants were surveyed over three time periods: 2001-2002, 2003-2004, and 2005-2006. Participants were asked whether they had used a nicotine replacement therapy in the form of the nicotine patch (placed on the skin), nicotine gum, nicotine inhaler, or nasal spray to help them quit, and if so, what was the longest period of time they had used the product continuously. They also were asked if they had joined a quit-smoking program or received help from a doctor, counsellor, or other professional.

The results showed that, for each time period, almost one-third of recent quitters reported to have relapsed. The researchers found no difference in relapse rate among those who used NRT for more than six weeks, with or without professional counselling. No difference in quitting success with use of NRT was found for either heavy or light smokers.

"This study shows that using NRT is no more effective in helping people stop smoking cigarettes in the long-term than trying to quit on one’s own,” Alpert said. He added that even though clinical trials (studies) have found NRT to be effective, the new findings demonstrate the importance of empirical studies regarding effectiveness when used in the general population.

The study appeared in an advance online edition of Tobacco Control and will appear in a later print issue.
