Experts are worried as a cheap drug is spreading fast, especially in French speaking Switzerland.
Known as 3-MMC, it’s a synthetic mix of cocaine and amphetamines.
It can trigger psychotic episodes and convulsions as well as causing high blood pressure.
It’s said to be highly addictive. Currently it's thought to be taken only by a few people in a close network. But it’s becoming more and more common in France and there are fears it's only a matter of time before it breaks out to the wider population here.
Police have already seized several batches in canton Vaud.
