The Greens are calling for cannabis to be legalised for recreational and medical use:
The Green Party say it will legalise cannabis if it forms a government next year.
Under its proposal, people would be able to legally grow and possess marijuana for personal use.
The Green Party would also urgently amend the law so sick people using medicinal marijuana were not penalised.
The full policy is here, but it basicly recognises that waging war on cannabis users causes more harm than good and we would be better off simply regulating it like tobacco. That'll take a while, so in the short-term they're pushing for full implementation of the Law Commission's recommendations (which would basicly stop prosecutions of users and "social dealers") and removing all legal penalties for medicinal users. Its a sensible policy which recognises the utter stupidity and waste of the "war on drugs" and instead approaches drugs from a public health perspective. The question is whether they can convince Labour, or whether there's still just too many old farts in the establishment party.
