Summary: | Aims
To estimate linear time‐trends in substance use and primary prevention variables in adolescents in Iceland from 1997 to 2014.

Repeated, cross‐sectional population‐based school surveys with seven waves of pooled data.
Setting: Iceland.
Participants
All accessible students enrolled in the 9th and 10th grades in the national Icelandic school system during the spring of 1997, 2000, 2003, 2006, 2009, 2012 and 2014 (n = 50 412, boys = 50%). Response rates ranged between 81 and 90% of the population.
Measurements
Measures on substance use included smoking and alcohol use. Primary prevention measures included parental monitoring, parental social involvement, participation in organized sports and reduced participation in a party life‐style.
Findings
