Declarations
:
: We used a secondary anonymized dataset collected by the Norwegian Social Research Institute (NOVA) and the regional Drug and Alcohol Competence Centers. Because the dataset was without collection of personal identifiable data, specific ethical approval was not required for this study and was waved by the Norwegian Centre for Research data (NSD). We conducted the analyses in accordance with the NSD’s data protection regulations. Participation was voluntarily. Parents of all participants were informed about the survey in advance and were given the opportunity to withdraw their children from participation. No formal verbal or written consent was obtained.
: Not applicable as this was an anonymized secondary data source.
: The authors declare that they have no competing interests in this section.
