Source: Victorian Pill Testing Service
A sample expected to be 4-MMC (mephedrone) was found to be 4-CMC.
What is 4-CMC?
- 4-Chloromethcathinone (4-CMC) is a cathinone stimulant, also known as clephedrone
- 4-CMC effects are different to the effects of 4-MMC (mephedrone)
- If you are expecting 4-MMC (mephedrone) but take 4-CMC, you may believe the substance isn’t working, and take more
- High doses of 4-CMC can be unpredictable and dangerous
Risks:
High doses of 4-CMC can lead to long periods of unwanted stimulation. This can include:
- Sleeplessness
- Anxiety or agitation
- Paranoia and hallucinations
- Nausea and vomiting
- Heart problems
Risks are increased with other stimulant drugs like MDMA, methamphetamine, or cocaine.
Seek medical help immediately if you experience:
- Overly fast heart rate or chest pain
- Agitation, anxiety, paranoia, or hallucinations
- Overheating
- Vomiting repeatedly
- Collapse or seizures
Harm reduction advice:
- Start low, go slow. Delayed or different effects could be a sign of unexpected ingredients like 4-CMC
- If the effects are not as expected, don’t take more
- Stay cool, take breaks from the heat, stay hydrated
- Make sure you’re in a safe environment and with people you trust
- Call triple zero ‘000’ if you are concerned
