"Illegal drug use is in decline in England and Wales with cannabis use at its lowest level for a decade, according to a report. Despite the fall in use of cannabis, the Government said it was determined to press ahead with reclassifying the drug from Class C to Class B in January. The Home Office said the decision to reclassify was taken on the basis of the potential of cannabis to cause harm not on the prevalence of its use."
