Please note: Mephedrone is a relatively new drug. To date, there is limited evidence of how widely it is used in Australia. Due to the lack of formal research about its use and effects, much of the information used in this fact sheet has been taken from people who have used the drug, rather than from scientific sources. (This page will be updated once more information is known.)
