Expatriate smokers with international health insurance who wish to give up the habit have a new tool to assist them in the challenge.
Txt2stop provides encouraging text messages to ex-smokers to encourage them to continue abstaining from nicotine.
It has been found to double someone's chance of cessation compared with solitary attempts, claimed Dr Caroline Free of the London School of Hygiene and Tropical Medicine, who is involved in the programme.
She explained that clients are asked to provide a quit date. They will then receive "an intensive period of support" for around seven days before this point and for several weeks afterwards.
The texts customers would receive, such as "congratulations, your oxygen levels are normal, well done, keep going", or "your cravings may be strong today, but don't worry, they will become easier tomorrow", are designed to be particularly relevant to certain times of nicotine withdrawal, Dr Free noted.
Support of any kind generally doubles someone's chances of ceasing tobacco consumption, she declared.
Half of all smokers aged over 35 will die from an illness contracted as a result of the habit.
