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.
The following table provides trend data between the 2002-03 and 2006-07 BCS for the proportion of cocaine powder users aged 16 to 24 years who reported to using cocaine frequently (more than once a month) in the previous year. The latest figures show that although there was an increase in the proportion of 16 to 24-year-old cocaine powder users who report being a frequent user between the 2002-03 and 2006-07 BCS (from 18.9 to 25.6) this was not statistically significant as these estimates are based on small samples and subject to large margins of error. Larger differences are required to detect statistically significant changes over time.
