Following the revelation in a biography of the leader of the conservative party that he smoked cannabis as a 15 year old school boy I wrote this on the 'Have your Say' section of the BBC web site but I doubt it will be published so you can read it here:

Given the powers of cannabis, we can see that Cameron is clearly suffering from its longer term effect.

More than that, it strikes me that William Hague has a lot of explaining to do. UPDATE: Cameron has just been on the radio to say that he has done things in the pst that his is sorry for but he's not going to admit or deny anything to do with the latest revelations.
