There's something about hearing your partner/best friend/daughter nag you to quit smoking that makes you want to light up.

But what if that intervention was less irritating and came from a relatively inoffensive text message? Would it help you kick your habit?

The London School of Hygiene and Tropical Medicine tested that theory in a trial with 5,800 British smokers. They found smokers who received motivational texts - such as, "TODAY is the start of being QUIT forever, you can do it!" - were more than twice as likely to quit smoking versus participants in the control group who received non-motivational texts, according to the AFP. Researchers determined who had quit using saliva tests to detect cotinine, a chemical found in tobacco.

The group that received texts had a success rate of 10.7 per cent, whereas those in the control group had a rate of 4.9 per cent. The results of the study were published in the medical journal The Lancet.

The SMS service also served as an automated sponsor of sorts. If a participant texted "crave" to a given number, he would receive a reply with practical advice on how to overcome the temporary desire to light up.

"Cravings last less than 5 minutes on average. To help distract yourself, try sipping a drink slowly until the craving is over," was a sample response.

The study's lead researcher, Caroline Free, told the AFP the system is a convenient and easy to implement on a wide scale, since so many people have cell phones. No doubt it's cheaper than the patch and less annoying than a judgmental spouse.

"People described txt2stop as like having a 'friend' encouraging them or an 'angel on their shoulder'. It helped people resist the temptation to smoke," Dr. Free told the AFP.
