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 the last year, with 6.7 per cent of adults aged 16 to 59 using it in the last year, similar to the 2013/14 survey (6.6%; Figure 1.2). Over the longer-term, between the 1998 and 2003/04 surveys, the last year use of cannabis was stable, at around 10 per cent of adults, before falling to 6.5 per cent in 2009/10. The trend since the 2009/10 survey has been relatively flat, at between six and seven per cent (Table 1.02).
"Among younger adults aged 16 to 24, cannabis was also the most commonly used drug, with 16.3 per cent having used it in the last year. This was not statistically significantly different from the level in 2013/14 (15.1%), but was a significant fall compared with the 1996 survey (25.8%).
"Although the trend in the use of cannabis among 16 to 24 year olds appears to have shown a steady increase compared with the 2012/13 survey, it is too early to conclude that this is an emerging pattern at this stage. The estimates from the 2012/13 survey appear to be out of line with recent results, and a comparison of the latest estimate to previous years may indicate that the trend, which has been falling since the peak in 1998, has gradually stabilised (Table 1.06)."
