The study did not find the same association for women or nonsmokers

(CNN)Men who took high doses of vitamin B6 and B12 supplements had a higher risk of lung cancer, and the association was highest among current smokers, according to a study published Tuesday.
The study found a 30% to 40% increased risk of lung cancer among men taking these vitamins from individual supplements -- not from multivitamins or diet alone. But the effect seemed to be driven by current smokers who far exceeded the recommended daily amounts of the vitamins, according to study author Theodore Brasky, an epidemiologist in the division of cancer prevention and control at the Ohio State University College of Medicine.
"I think these results point to a synergism" between high-dose B vitamins, smoking and lung cancer risk among men, Brasky said.
