The NordAN conference in Oslo will focus on the overarching theme "From Harm to Zero?" This year's conference aims to explore effective strategies and policies to reduce the harm caused by alcohol and drug use in society while addressing the challenges faced by traditional Nordic alcohol policy in the region. Through a series of plenary sessions, attendees will engage in in-depth discussions on the gradual erosion of alcohol control policies, the latest Nordic Nutrition Recommendations, and effective measures and interventions in drug policy.
