Please note: Mephedrone is a relatively new drug, and so far 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 page has been taken from reports from people who have used the drug, rather than scientific sources.
Mephedrone (4-methylmethcathinone) was originally marketed as a plant fertiliser and 'research chemical'.

How mephedrone affects a person depends on many things including their size, weight and health, also whether the person is used to taking it and whether other drugs are taken around the same time. The effects of any drug also depend on the amount taken.

People who have used mephedrone describe the effects as being similar to ecstasy, and estimate that the effects last between 2 and 4 hours. Some also say that the drug can be compulsive ('more-ish') to use, and can create a state of psychological dependence. Many report that the negative effects become far more severe with heavy use.

The symptoms of coming down and withdrawal can also affect the ability to work safely and effectively.
Preventing and reducing harms
The use of mephedrone carries a risk of harm. This risk is increased when:
