The British crime survey (BCS) only collects information about frequent drug use among young people aged 16 to 24 years. Questions on frequency of use in the last year were first asked in the 2002-03 BCS.
Table 1 provides trend data between the 2002-03 and 2006-07 BCS for the proportion of cannabis users aged 16 to 24 years who reported to using cannabis frequently (more than once a month) in the previous year. The latest figures show that there was a statistically significant decrease in the proportion of 16 to 24-year-old cannabis users who report being a frequent user between the 2002-03 and 2006-07 BCS (from 46.1 per cent. to 37.0 per cent.).
