It is now being reported that in the tragic case of Louis Wainwright and Nicholas Smith, two teenagers who died back in March, neither of them had taken the now banned (but then legal) drug mephedrone.
The case kicked off a media panic about the drug when it was rumoured that they had taken it. The political furore that then ensued ultimately led to the banning of the drug just before the General Election.
There have also been other cases where initial reports have suggested the drug was involved only for it later to turn out not to have been the case. This is one of the reasons why many at the time were pleading for more time for the ACMD to reach its decision about the drug - they needed more and more accurate information.
Eric Carlin, a former member of the ACMD who resigned in protest at how political pressure was being applied regarding mephedrone has said that the decision to ban the drug should be "revisited" in light of the findings, and the "public health consequences" of the ban needed to be considered. he went on to say:
"The fact these two people died and it's not actually connected with mephedrone just emphasises the fact that we were under a lot of pressure to ban this drug and these cases were actually cited as being examples of why that was necessary."
In fact there has only been one case so far in the UK where mephedrone has been established as the cause of death.
This latest revelation about the March cases underlines how important it is for government policy to be based on evidence and not media panic stories.
We can but hope that the new administration is more circumspect in its approach the next time there are a rush of unproven stories about one particular drug.
