[Margaret Pilkington]

So now Lord Hague has thrown his hat into the ring and made the suggestion that cannabis should be legalised....that the drug war is lost.

The drug war is not lost, it has been surrendered by an unwilling police force.
A law is only as good as the policing of it. A toothless law is a useless law.
If it is not actively and vigorously policed then it just might as well not be there at all.

What other illegal practices are going to be ditched because the police have neither the time nor the inclination to pursue those who are breaking the law?
Is the legalisation of a psychoactive drug just a way for governments to extract another level of tax from users?
Will this pay for enough care needs to deal with the mental health issues (well recognised and documented) that users may suffer from?
