HEALTH BEHAVIOUR IN SCHOOL-AGED CHILDREN: WHO COLLABORATIVE CROSS-<strong>NATIONAL</strong> STUDY (HBSC) 2014 SURVEY IN SCOTLAND <strong>NATIONAL</strong> REPORT DRUNKENNESS Overall, thirteen percent (13%) of young people have been drunk on at least two occasions. Prevalence of drunkenness is much higher among older adolescents; 34% of 15-year olds report having been drunk at least twice compared with 6% of 13-year olds. Less than 1% of 11-year olds have been drunk this often (Figure 12.10). There are no gender differences in reports of drunkenness at any age. Reporting of drunkenness among 15-year olds increased in the 1990s and has subsequently declined (Figure 12.11). Fifteenyear old girls showed a marked decrease in drunkenness over the past four years (from 47% to 34%), bringing the level in 2014 in line with rates for girls this age in 1990 (36%). Among boys, there was also a decrease in drunkenness from 40% in 2010 to 33% in 2014, meaning that the prevalence in 2014 is now lower than in 1990 (44%). FREQUENCY OF CANNABIS USE AMONG 13- AND 15-YEAR OLDS Eighteen percent (18%) of 15-year olds and 4% of 13-year olds have used cannabis at least once in their lives (Figure 12.12). There is no gender difference in lifetime use of cannabis at either 13 or 15 years. Ten percent (10%) of 15-year olds and 2% of 13-year olds reported cannabis use within the previous month (Figure 12.13), with 15-year old boys being more likely to have used cannabis in the previous month than 15-year old girls (13% versus 8%, respectively). Between 2002 and 2010, there was a decrease in lifetime cannabis use among 15-year olds, however the prevalence has not changed since 2010 (Figure 12.14). Use of cannabis in the past month has changed little amongst 15-year old boys since 2002, but there has been a slight decrease among 15-year old girls from 12% in 2002 to 8% in 2014 (Figure 12.15).
