From the Times, yesterday:

The public was misled about the dangers of taking cannabis when the Government unwittingly decided to downgrade the drug less than a year ago, the Home Secretary admits today. In a damning assessment of the decision taken by his predecessor, David Blunkett, Charles Clarke said he is ‘very worried’ about recent evidence suggesting a strong link between cannabis and mental illness. His remarks, made in an interview with The Times, come just weeks before he must decide whether or not to execute an embarrassing about-turn and restore the drug’s Class B status.

Mind-bender: unwittingly
Truth: idiotically

Interpretation: there was already a significant body of evidence that cannabis either caused or provoked mental illness when the government reclassified the drug to a category of lesser harm. It refused to listen, choosing instead to take the word of open and covert drug legalisers among its advisers. The harm it has done to the lives of both the users and their victims has been incalculable.
