Youth twice as likely to transition from use to weekly use of cannabis in legalizing states compared to non‐legalizing states

In future studies, the researchers hope to discover what specific elements of vaping prevention video ads make them effective. “To what extent is ad effectiveness dependent on the characters featured in an ad, the ad content, format, production value, and other features? That is what we plan on studying in future work,” Noar said. The video ads used in the study can be found on UNC’s online Vaping Prevention Resource, a website designed to provide practitioners, researchers and communities with vaping prevention media content from around the world, as well as policy solutions for youth vaping prevention. It is the largest online repository of free open-access vaping prevention materials. Noar has served as a paid expert witness in litigation against tobacco and e-cigarette companies. One other author has served as a paid consultant on litigation against tobacco companies. All other authors have no conflicts of interest to report. The research was supported by the FDA and the National Cancer Institute. ▪ Noar SM, Gottfredson NC, Kieu T, et al.
