Article Synopsis
- The study investigated how introducing draught alcohol-free beer in pubs and bars in England affected the sales of alcoholic beverages and overall revenue.
- It involved a randomized crossover trial in 14 venues, alternating between periods of selling the alcohol-free option and normal operations over eight weeks.
- Findings showed that the sale of draught alcoholic beer dropped by 4% to 5% with the introduction of alcohol-free beer, but there was no significant change in total revenue from all drinks.
Background: Increasing the availability of non-alcoholic options is a promising population-level intervention to reduce alcohol consumption, currently unassessed in naturalistic settings. This study in an online retail context aimed to estimate the impact of increasing the proportion of non-alcoholic (relative to alcoholic) drinks, on selection and purchasing of alcohol.
Methods And Results: Adults (n = 737) residing in England and Wales who regularly purchased alcohol online were recruited between March and July 2021.
Article Synopsis
- This study investigates whether reducing cigarette pack sizes from 25 to 20 can help smokers cut down on their daily intake.
- Conducted as a randomized controlled trial in Canada, adult smokers participated in two 14-day periods where they smoked from both pack sizes.
- Results showed that participants smoked an average of 1.3 fewer cigarettes per day from the 20-pack compared to the 25-pack, indicating that smaller pack sizes may encourage reduced smoking.
Health warning labels (HWLs) show promise in reducing motivation towards energy-dense snack foods. Understanding the underlying mechanisms could optimise their effectiveness. In two experimental studies in general population samples (Study 1 n = 90; Study 2 n = 1382), we compared the effects of HWLs and irrelevant aversive labels (IALs) on implicit (approach) motivation towards unhealthy snacks, using an approach-avoidance task (Study 1), and a manikin task (Study 2).

Design: Between-subjects randomised experiment using a 2 (e-cigarette retail display visibility: high vs low)×2 (proportion of e-cigarette images: 75% vs 25%) factorial design.
Setting: Online via the Qualtrics survey platform.
