As more employers decide not to hire smokers, a new study underscores why: Puffers cost employers $5,816 more per year than non-smoking employees. The author, an expert in public health law, teamed up with economists and dug into the topic after realizing there "wasn’t any really good study out there." NBC News shares the findings, which resulted from aggregating other studies to arrive at the final number—and included one morbid adjustment. The researchers took into account the fact employers might save on pension costs since smokers typically die younger.
