A study co-authored by Henriksen and ASPiRE researchers Monika Vishwakarma, Trent Johnson, and Nina Schleicher examined compliance at 614 California vape shops with state-mandated age-of-sale signs, the presence of age-of-entry signs, and the tobacco industry’s “We Card” sign in 2019. The researchers found that compliance with the age-of-sale sign was 69.4%, with vape-only stores less compliant than those that sold other tobacco products. Age-of-entry signs were more common in vape-only stores, but the difference was greater for vape-only stores near community colleges and attenuated for vape-only stores near 4-year universities/colleges. The authors concluded: “Improved enforcement and retailer education regarding age-of-sale signage are needed, particularly near colleges.” Read the paper.
