Research funded to study effects of lower nicotine levels.
Categories: New Grant Award
ORI scientist Herb Severson, Ph.D. has received funding from the National Institute of Drug Abuse (NIDA), University of Minnesota, and University of Pittsburgh to investigate the effects of smoking reduced nicotine cigarettes on smoking behavior and tobacco related health risk. In this 2-year, $ 1.3 million study, Severson and his team will collaborate with researchers in 10 different locations to compare experiences and behaviors of participants smoking different cigarettes with progressively lower levels of nicotine to experiences and behaviors of participants going “cold turkey” as well as participants maintaining standard levels of nicotine intake. Throughout the experiment, participants will record their use of tobacco products and complete questionnaires on mood and responses to their assigned cigarette type, and will have their biomarker samples analyzed in order to determine their exposure levels to nicotine and tobacco-related toxins. This research may help inform the Food and Drug Administration how best to regulate tobacco products in the future with the goal of improving public health.
