How many attempts does it really take to quit smoking? What the science says

Published on July 4, 2026 · 3 min read

"Failed again." That's often the first thought after a relapse, the one that makes you want to give up entirely. But from a scientific standpoint, that thought rests on a flawed assumption: that quitting smoking should work on the first try.

Numbers that vary, but tell the same story

According to VIDAL, a French medical reference, it takes 5 to 7 attempts on average before quitting for good. A University of Toronto study that followed 1,277 smokers over 10 years puts the number as high as 30 attempts when counting every micro-relapse over the long run. On the other hand, a survey by the French Federation of Patient Associations found that 80% of smokers succeeded within two attempts. The gap between these numbers isn't a contradiction, it simply shows the path looks very different from one person to the next, and none of these figures is an individual verdict.

Why relapse is part of the process

Nicotine dependence behaves like a chronic, relapsing condition, not like an exam you pass or fail. Santé Publique France's 2024 Baromètre, the French national public health survey, confirms that most smokers who want to quit have already made at least one attempt before their current one. Every attempt isn't a box checked as failure, it leaves real traces: reflexes learned, a better understanding of the cravings involved.

That's exactly what Thomas went through: it took him three attempts before it truly stuck. What changed the third time wasn't willpower, it was how he stopped aiming for perfection after a relapse.

What genuinely increases your odds

One point is consistent across studies: an attempt supported by a healthcare professional roughly doubles the odds of success compared to going it alone, support that's often free or nearly free and that many smokers never even consider. Combining that support with concrete reflexes for handling cravings, like the ones that helped Marie make it through her first six months, builds a far sturdier foundation than a decision made on a whim.

The real number worth tracking isn't how many attempts you've already made, it's what each one taught you. A relapse that teaches something is never an attempt wasted.

Frequently asked questions

Does a relapse mean I've failed?

No. Studies agree that multiple attempts are the norm, not the exception, with averages ranging from 5 to 30 depending on methodology. Each attempt builds tolerance and reflexes that improve the odds of the next one.

Which attempts succeed the most?

Those supported by a healthcare professional, which statistically double the odds of success compared to quitting alone, especially combined with concrete craving-management techniques.

How long should I wait before trying again after a relapse?

There's no universal timeframe. What matters most is identifying what triggered the relapse before starting a new attempt, rather than jumping back in without changing anything about the approach.
