It can also be found in capsules and tablets, but this is much less common.

Physical health risks
Taking mephedrone involves risks – and the dangers and long-term effects are becoming clearer as more reports emerge.
Here’s what we know:
- There are several deaths a year in the UK from people taking mephedrone.
- Some users have reported blue or cold fingers – probably because mephedrone affects the heart and the circulation.
- There have been reports of people being hospitalized due to the short-term effects of mephedrone.
- Some users have had severe nosebleeds after snorting mephedrone.
- It risks overstimulating and damaging your heart and your circulation.
- It risks overstimulating your nervous system, which may cause hallucinations, feelings of agitation and even fits.
- Overheating has been a significant cause of deaths when other amphetamine-type drugs, such as ecstasy, have been used along with mephedrone.
- Injecting mephedrone is particularly dangerous for several reasons, including the fact that it’s easier to overdose from injecting.
Mental health risks
Mephedrone can lead to:
- loss of short-term memory
What is mephedrone cut with?
Mephedrone is sometimes cut with:
- monosodium glutamate (normally used as a flavour enhancer)
- benzocaine (a local anaesthetic which can produce a ‘numbing’ effect)
Is it dangerous to mix with other drugs?
Yes. You increase the risks to yourself, including the risk of death, if you combine alcohol with mephedrone or any other drug that causes a high.
Also, you can never be entirely sure that what you’re buying is actually mephedrone and not something else.
