Under increasing pressure from the media, the UK government has introduced an amnesty for all mephedrone suppliers of existing stock and made the drug a class B substance.
The legislation attempts to cover all possible chemical variations and compound structures, which could have allowed a legal way round the ban. Mephedrone is now an illegal substance to possess, supply or import in the UK. Standard class B legal penalties apply upon charges brought by the police.
How Mephedrone will be treated and classified by Europe and the rest of the world remains unclear. It remains a legal chemical in many countries.
There is still no instant drug test for mephedrone available, making its use, problematic to detect or monitor.
