Ever wonder why some teens who try cigarettes get hooked quickly and others don’t? The answer may lie in their genes, according to a new study that spans nearly four decades.
Researchers used data from earlier studies to construct a genetic risk score for heavy smokers. Next, they screened the genes of about 1,000 New Zealanders from birth to age 38 to see whether those with high risk scores got hooked on cigarettes more quickly as teens and whether they had a harder time kicking the habit as adults.
