Unfortunately reactions such as we've seen to the Gove thing is why we can't have a proper drugs debate in this country.
This.
My only previous comment on this thread is to note Gove's hypocrisy (as have others). No point adding further whimsical anecdotes or lofty viewpoints.
Regarding the impossibility of a sensible debate, I realised something was afoot in the truth stakes when I was a student and there was a war in Zaire, and the TV news reported a massacre by fighters in a 'frenzy' and whose 'faces were bloated with cannabis'.
