"The SCJS 2010/11 estimated that:
" Just under one in four (23.7%) adults reported taking one or more illicit drug at some point in their lives (ever), even if it was a long time ago;
" One in fifteen (6.6%) adults reported using one or more illicit drug in the last year, i.e. the 12 months prior to the survey interview;
" One in twenty eight (3.5%) adults reported using one or more illicit drug in the last month, i.e. the month prior to the survey interview.
"Cannabis was by far the drug most commonly reported in any of the 3 time periods asked about with around one in seventeen (5.6%) adults reporting cannabis use in the last year. Cocaine and ecstasy were the next most commonly reported drugs used after cannabis in the last year (1.9% and 1.4% respectively)."
