Unscrupulous drug dealers are flooding Britain with a dangerous new legal high that could put thousands of young lives at risk.
Pushers expect to make millions of pounds from the untested substance dubbed the new Meow Meow.
They are desperately trying to flog as much of it as possible before a blanket ban on legal highs comes into force next year.
A Mirror investigation has uncovered links between the drug, which we have decided not to name, and two businessmen based in the North.
A website boasting of making and distributing the £15-a-gram high insists it is chemically identical to Meow Meow, which was banned five years ago after being linked to dozens of deaths.
