Background and aims
Variation in the TAS2R38 taste receptor gene alters the ability to taste bitter compounds. We tested whether TAS2R38 variation influences early smoking behaviours in adolescence, a critical period of acquisition when taste may influence the natural course of tobacco use.
Design and participants
Observational study (Nicotine Dependence in Teens [NDIT]). Cox proportional hazards...
Background and aims
There are few longitudinal studies assessing the association of cannabis use and subsequent onset of bipolar disorder. We aimed to measure the association between early cannabis exposure and subsequent bipolar disorder.
Design, Setting and Participants
Observational study linking a sample from the northern Finland birth cohort 1986 (n = 6325) to nation‐wide register data to...
Background and aims
Alcohol use increases throughout adolescence. Emergency department (ED) attendance is an opportunity for alcohol screening and brief intervention (ASBI), which is effective for adults. This trial evaluated the effectiveness and cost‐effectiveness of ASBI compared with screening alone (SA) in high‐risk adolescents.
Design, Setting and Participants
Multi‐centre, three‐group, single‐blind,...
Aim
To (i) estimate the prevalence of adolescent vaping in 47 lower‐middle, upper‐middle and high‐income countries, and (ii) test the association between implementation of World Health Organisation (WHO) tobacco control policies and adolescent e‐cigarette use (also known as vaping) in 44 countries where implementation data were available.
Design
Cross‐sectional surveys.
Settings
A total of 47...
