No Evidence for Claims of Explosion of Cannabis Use
Media claims of an explosion of cannabis use following reclassification in January 2004 have pressured Home Secretary Charles Clarke to call for a review of policy from the Advisory Council on the Misuse of Drugs.
However new figures released today (March 2005) by the Independent Drug Monitoring Unit, based on a 10 year study involving over 16000 cannabis users, finds key indicators of cannabis use to show no evidence of any such increase.
Indeed, preliminary findings from the 2004 IDMU survey recorded the lowest
year on year increase in regular cannabis use in the past decade, with user
ratings (a key indicator of intention to use) remaining at a historic low.
The average age of initiation to cannabis use was close to the 10 year average,
and cannabis resin prices had bottomed out after years of steady decline.
Matthew Atha – IDMU Director, stated today “Far from leading to
an explosion of use, declassification of cannabis appears to have had little
or no effect on consumption or levels of cannabis usage, if anything the upward
trend in cannabis use appears to have been halted.”

Notes to Editors: The figure for regular cannabis users is derived from the average number of times an respondents have been ‘busted’ for cannabis, their duration of use, the number of cannabis arrests over the average duration of use (derived from Home Office statistics), and the proportion of regular cannabis users in each year’s survey.
IDMU distributes anonymous questionnaires at Pop Festivals and other outdoor events around the UK. The 2004 results are based on the preliminary dataset of 2056 respondents. The 2005 survey can also be found by clicking here. For further Information contact Matthew Atha
