Regular readers will recall the confused mess that is this government’s (UK) cannabis policy. There has been a drop in cannabis consumption since it was downgraded from Class B to C, but nevertheless they want to put it back up to Class B again. Yes, we know all about the argument that what you ingest is entirely your business, it being your body and all that but morals are always trumped by politics.

In the comments section to our last piece the general consensus was that the policy was driven either by a craven servility to the Murdoch press or, as a daring alternative, a bending to Daily Mail woo woo. The general consensus however was that it was Puritanism, that awful fear that someone, somewhere, might be enjoying themselves and that this situation cannot be allowed to continue. We’re arguing over whose Puritanism, not whether.

Thus there really is no logical leg for the government to stand upon in its reclassification of cannabis: there's not in fact one reason against the legalisation of the damn stuff and the increase in liberty and freedom that would result.
