When you make a mistake, admit it - and put it right.
It has taken Associate Minister of Health Peter Dunne and the Government a long time to admit they got it wrong with legal highs, but at the weekend they did so, and next week these potentially lethal drugs will be banned.
The good intentions of Mr Dunne's Psychoactive Substances Bill, passed last July, have been swept away by reports revealing the psychotic behaviour brought about by these products.
The weight of evidence of the damage, coupled with the public outcry in many communities - including here in Wanganui - made the continued legalisation of these drugs untenable.
New Zealand has been involved in a bizarre and unique experiment, approving the sale of various permutations of synthetic cannabis while everyone knew we would be better off without them.
