Dear 2015: I Commit To Butt Out

Sue Li Blog Article postLung cancer is the leading cause of cancer death in Canada and smoking accounts for more than 85% of these cases (1). While butting out is among the top 3 New Year’s resolutions, a surprising estimated 80% of people actually keep their resolutions for more than 24 hours (2). When it comes to smoking, it’s tough to quit cold-turkey. Did you know that it takes smokers an average of 7 attempts before actually being smoke-free?

Medications such as Nicoderm, Nicorette or the Varenicline (Champix) pill, act to substitute nicotine – the key addictive chemical in cigarettes – in our bodies. These drugs can help improve your chances of quitting, but the way in which your body handles nicotine may play a big role in determining which medication is the most effective for you. In a recent study, researchers compared quit rates among smokers on the nicotine patch to those given Champix and asked participants to state which was best to help butt out (3). It turns out the answer lies in the rate at which your body can break down (metabolize) nicotine. Researchers found that normal nicotine ‘metabolizers’ were more likely to stay smoke-free after 11 weeks of taking Champix than the nicotine patch. On the other hand, for slower nicotine ‘metabolizers’, the quit rates were similar regardless of whether they used the nicotine patch or took Champix. However, those treated with Champix reported more unwanted side effects, suggesting that this group of people would benefit more from using nicotine patches. While more studies will be needed, one thing is for sure – it’s never too late to quit!
