Postdoctoral fellow, Dr. Morgan Snell, published a paper describing associations between nicotine dependence and dual use of combustible and e-cigarettes over time. The paper, entitled, "A Longitudinal Analysis of Nicotine Dependence and Transitions From Dual Use of Cigarettes and Electronic Cigarettes: Evidence From Waves 1–3 of the PATH Study," was published in the Journal of Studies on Alcohol and Drugs. Study investigators found that highly-dependent adults were more likely to remain or become dual users rather than exclusive users of either product.
