Self-reported harm from others' alcohol, cigarette and illegal drug use in Norway.

Aims: While it is documented that substance use harms others than the user, less is known about which substances people experience most harm from, and who the victims and perpetrators are. The aims were: (i) to estimate the prevalence of and overlap in self-reported harm from others' alcohol, cigarette, and illegal drug use; (ii) to examine potential differences in the prevalence of harm from close relations' and strangers' use; and (iii) to examine how the prevalence of harm varies according to demographics and the respondents' substance use.

Methods: Population surveys conducted among 16-64-year-old Norwegians in 2012 and 2016 ( = 3407) assessed self-reported harm from others' alcohol, cigarette and illegal drug use with identical measures, demographic variables and the respondents' substance use.

Worries about others' substance use-Differences between alcohol, cigarettes and illegal drugs?

Background: While it is well documented that many experience harm from others' substance use, little is known about the psychological strain associated with others' use. The aims were: (1) to describe the prevalence of worries about others' alcohol, cigarette and illegal drug use, (2) whose substance use people worry about, (3) the overlap in worries, and (4) to examine how worries about others' use of each substance vary according to demographics, own substance use and experience of harm from others' use.

Methods: A population survey was conducted among 16-64year old Norwegians (N=1667).

Latent developmental trajectories of episodic heavy drinking from adolescence to early adulthood: Predictors of trajectory groups and alcohol problems in early adulthood as outcome.

Introduction And Aims: To identify latent developmental episodic heavy drinking (EHD) trajectory groups for Norwegian adolescents, investigate risk factors associated with group membership and to assess differences in alcohol problems between different groups in early adulthood.

Design And Methods: Data were from 1266 individuals measured at four time points from age 13/14 years to age 26/27 years. Latent class growth analysis was used to identify groups with different EHD development.

Harm from others' drinking: How problematic do people with and without experience of harm perceive it to be?

Background: The aims were (1) to map how problematic people perceive it to be that a person experiences different types of harm from others' drinking, (2) to describe how problematic victims of harm from others' drinking perceive the experience to be, and 3) to investigate how perceptions of harm from others' drinking vary according to demographic characteristics, own drinking and experience of harm.

Methods: 2182 persons in Norway aged 18-69 years participated in a panel web survey in 2013. They responded to questions about six types of harm from others' drinking.

Harm Experienced from the Heavy Drinking of Family and Friends in the General Population: A Comparative Study of Six Northern European Countries.

Background: Epidemiological research on alcohol-related harm has long given priority to studies on harm to the drinker. A limitation with this perspective is that it neglects the harm drinking causes to people around the drinker, and thus, it fails to give a full picture of alcohol-related harm in society.

Aim: The aim was to compare the prevalence and correlates of experiencing harm from the heavy drinking by family and friends across the Nordic countries and Scotland and to discuss whether potential differences match levels of drinking, prevalence of binge drinking, and alcohol-related mortality.
