A team of researchers, including two at Brown University, show that when people smoked cigarettes with less nicotine, they smoked less, felt less craving, and tried to quit more. Results appear in The New England Journal of Medicine.

A new study by researchers in Brown University’s Center for Alcohol and Addiction Studies finds that children given a sip of alcohol before sixth grade were more likely to have had a full drink or have gotten drunk by ninth grade than those who didn’t get a sip. But the study reveals only an association, not proof of a cause, the researchers caution.
