Prevalence of Last-Year Cannabis Use in England and Wales Among People Aged 16 to 59
"As in previous years, cannabis was the most commonly used drug in 2016/17, with 6.6 per cent of adults aged 16 to 59 having used it in the last year (around 2.2 million people), similar to the 2015/16 survey (6.5%). However, this is statistically significantly lower than a decade ago (8.2% in 2006/07) and the start of measurement in the survey in 1996 (9.4%). The trend from the 2009/10 survey onwards is relatively flat, remaining between six and seven per cent, as illustrated by Figure 1.2 (see Appendix Table 1.02 for detailed figures).
"Among younger adults aged 16 to 24, cannabis was also the most commonly used drug in 2016/17, with 16.4 per cent having used it in the last year (around one million young adults). This was similar to the 2015/16 estimate (15.8%), but was statistically significantly lower than the 2006/07 survey (20.9%) and the 1996 survey (25.8%). Similar to the trend for the wider age group, the trend in cannabis use among young adults has been relatively flat since the 2009/10 survey year, although it does show more fluctuation from year to year."
