A simple DNA test could spot which smokers have an addictive gene and would likely benefit from particular quit methods, say scientists.
Smoking cessation treatment could be tailored according to the individual's gene profile, according to the Oxford University Team. The NicoTest, developed by g-Nostics, can be carried out in the same way that diabetics self-test for blood-sugar.
Those found to have the addictive gene, present in about 35% of all people, have a greater chance of quitting their habit if they use nicotine replacement therapy (NRT). Those without the gene are likely to succeed if they use other methods nicotine-free methods.
