„The prevalence of lifetime use of tranquillisers or sedatives without a doctor’s prescription was generally stable across years in the large majority of ESPAD countries. Between 2015 and 2019, a significant decrease in prevalence was observed in Bulgaria, Croatia, Czechia and North Macedonia. In contrast, Austria, Denmark, Estonia, Latvia, Lithuania and Slovakia showed a significant increase in prevalence over the same time period.“
