Legalising and taxing cannabis could be worth as much as £1.25bn a year to the government, a study suggests. The report Licensing and regulation of the cannabis market in England and Wales: towards a cost-benefit analysis, quantifies the revenue to be gained from the regulation and taxation of the cannabis market in England and Wales. It estimates that reduced enforcement costs, such as police, court and prison time and community sentences, could save £300m or more alone, with the remaining three-quarters of the net benefit come from tax revenue.
Police discovered more than 20 cannabis farms and factories in the UK every day last year, seizing drugs worth up to £100 million, according to a report by the Association of Chief Police Officers (ACPO). Criminals attempt to reduce risk and minimise potential losses by employing a large number of so-called "gardeners" to manage smaller farms across residential neighbourhoods. A total of 7,865 farms were found across the UK in 2011/2012, an increase of 15 percent from the 6,866 found in 2009/2010 and up more than 150 percent from the 3,032 found four years ago, the ACPO study found.
