Quit smoking success rates: Nicotine patch

Every day we get visitors to our site asking about the success rate for other quit smoking methods, so today I would like to focus on one of the most popular (and least effective!) quit smoking aids: the nicotine patch.

The nicotine patch is an adhesive patch that releases nicotine into the bloodstream. It is marketed as a quit smoking aid, and for years manufacturers have claimed that the patch "double your chances of quitting" (this claim appears on the US Surgeon General's office, Health Canada, Cancer Society and Heart Assocation websites) but double it from what to what? From 50% to 100% or from 1% to 2%?

Believe it or not, it is actually much harder than you think to find out even something this straightforward. The reason for this is that researchers rarely quote an actual success rate. Instead they compare the success of a treatment to placebo or to no treatment and quote the difference as an Odds Ratio (OR). So if a treatment is twice as effective as placebo, it has an OR of 2. If it's half as effective the OR would be 0.5.

There have been hundreds of studies looking into the effectiveness of the nicotine patch. Cochrane's Review, an independent body examining evidence-based treatments, identified 111 trials covering over 40,000 smokers and concluded that the nicotine patch has an OR of 1.66 vs. placebo.

So, if you slap a nicotine patch on, then you have a 66% better chance of quitting than if you wore a patch with no nicotine. This is interesting to me. If nicotine replacement really worked, you would expect it to be two, three or even five times higher than placebo or using nothing at all.

Clive Bates, Director of Action on Smoking and Health in the UK and one of the most vocal supporters of nicotine replacement therapy sheds some light on this issue. In a post on a discussion thread in April 2002, Mr. Bates wrote: "The unaided quit rate is about 3% success per attempt. NRT doubles that to 6%."

So, according to one of its biggest supporters, nicotine replacement therapy (NRT) has a success rate of 6% or, put another way, a 94% failure rate.

Allen Carr was dismissive of NRT from the beginning. He said "Telling a nicotine addict to stop using nicotine by taking nicotine is a bit like telling an alcoholic to drink beer instead of wine."

Ellen DeGeneres said it best: "The nicotine patch only works when you put one over each eye so you can't find your cigarettes!"
