"What we haven't tried, is the Dutch system. The Liberal Democrat system, of allowing adults in the UK to make an educated choice over whether they decide to use alcohol, or cannabis.
Lets face facts here. Its a choice 4 million take every single day and regardless of how the law stands.Cannabis use at a personal level has been decriminalised for 30 years in the Netherlands, and in that time they have constantly languished at the BOTTOM of the league for European drug addicts, and contrary to the best efforts of the United Nations "bookery cookery ".
Furthermore, they have no problems with drug factories setting up in residential areas because if the locals want to buy cannabis they can simply head down to their local "government licensed" premises and buy it, paying tax as they do. --http://pr.cannazine.co.uk/20080207151/cannabis-news/no-evidence-for-cannabis-reclass-nick-clegg-mp.html
CANNABIS CULTURE - UK's Liberal Democrats, polling higher than ever in the lead-up to a federal election, want to remove criminal penalties for cannabis possession and allow Dutch-style cannabis cafés.
Internal party policy documents leaked to the UK's Daily Mail suggest permitting possession, social supply to adults and cultivation for personal use. The release of the documents follows an internal party vote to make it "no longer a crime for the occupier or manager of premises to permit someone to use cannabis on those premises."
According to the Daily Mail, "cafe owners could allow customers to smoke the drug outside or buy ‘hash brownies’ and vaporised cannabis." --http://cannabisculture.com/v2/content/2010/05/04/Liberal-Democrats-Want-Legalize-Cannabis-UK
From wikipedia: HARM REDUCTION.
Harm reduction (or Harm minimisation) refers to a range of public health policies designed to reduce the harmful consequences associated with recreational drug use and other high risk activities. Harm reduction is put forward as an useful perspective alongside the more conventional approaches of demand and supply reduction.Many advocates argue that prohibitionist laws criminalize people for suffering from a disease and cause harm, for example by obliging drug addicts to obtain drugs of unknown purity from unreliable criminal sources at high prices, increasing the risk of overdose and death. While its critics are concerned that tolerating risky or illegal behaviour sends a message to the community that these behaviours are acceptable.
