Age-specific comparisons of first versus last years suggest that an increase in both past-month and past-year use was observed across all age groups in Europe (see Table 1). Among younger adults, cannabis consumption is overall more prevalent and absolute increases were more pronounced in this age group. Among 35 to 64 year-olds, increases were smaller in absolute terms but greater in relative terms. In this age group, prevalence of use increased by 50% or more between 2010 and 2019.Table 1Prevalence of past-month and past-year cannabis use in Europe, based on earliest and most recent survey estimates from 26 countriesTable 12010 12019 2Absolute prevalence difference 3Relative prevalence difference3PAST MONTH15 to 643·1 (2·3 to 3·9)3·9 (2·9 to 4·8)+0·8 (0·3 to 1·4)+26·6%By age group 15 to 247·0 (5·1 to 8·8)8·6 (6·5 to 10·6)+1·7 (0·6 to 2·8)+24·8% 25 to 345·1 (3·7 to 6·4)6·0 (4·5 to 7·6)+1·2 (0·3 to 2·1)+23·4% 35 to 442·0 (1·4 to 2·7)3·2 (2·1 to 4·3)+1·2 (0·6 to 1·9)+60·4% 45 to 541·1 (0·8 to 1·4)1·7 (1·0 to 2·4)+0·6 (0·1 to 1·1)+56·9% 55 to 640·4 (0·2 to 0·6)0·7 (0·4 to 1·0)+0·3 (0·1 to
