I hope I have answered this above. I would hope you would give serious consideration to this idea before we become a Country where the influence of criminal organisations goes beyond what the State is capable of tackling.
The criminalisation of recreational drug use in the UK must be addressed in order to tackle the ever growing problem of organised crime. One dreadful legacy of the past Labour Government has been the turning of a blind eye to the black market economy. In Glasgow (and I presume most other cities in the UK) criminal organisations are awash with drug money which they launder through sun bed salons, security firms, car washes or taxis. These people are not small community involved businessmen (as certain Labour councillors would have us believe) but exploitative, violent and corupt individuals.
I would suggest bringing illegal drugs under government control through a licensing system which managed the manufacture and sale of drugs. Cannabis, Amphetimine, Ecstacy, LSD and Cocaine should be de-criminalised and their sale in licensed premises, lets say between 10pm and 2am on a Friday and Saturday night with the amounts sold restricted, be permitted. Heroin, Crystal Meth and Crack Cocaine addictions could be tackled head on, perhaps in proper medical facilities.
I am not suggesting drug use is without risk. They are addictive substances. However, the current system pushes their use underground and into the hands of criminals. In prohibition USA alcohol was controlled by criminals. I cannot imagine people setting up illegal stills now alcohol is legal. Controlling the manufacture of drugs would at least allow people to make informed choices as to the quantity and type of drugs they took. The risk of taking contaminated substances would disappear, thus making these licensed substances the preferred option. All advertising of drugs would be banned with tax revenue raised going into addiction services and health warnings.
