There might be a reason some people can quit smoking cold turkey, while others feel that the only place cold turkey belongs is on a sandwich.
A recent study by the University of Colorado Boulder showed that genetic factors determine how difficult it can be to quit smoking.
The study also said that these genetic factors are more influential now than in the past, but regardless, the genetics explain why some people just can’t quit.
The study used adult identical twins who share an almost identical genetic structure, as compared with fraternal twins who do not.
The study showed that adult identical twins are significantly more likely to quit smoking at the same time compared with fraternal twins.
