In April 2010, Mephedrone being reclassified as a class B drug was thereafter banned in England. But recently it has been warned by one of the critical care paramedic in Emergency Medicine Journal that a new legal high has been materialized aiming to replace this banned substance.

This new drug in market is ivory wave and is also familiar by the name of purple wave, Ivory Coast, or vanilla sky.

According to the author of the Journal, Ivory wave is already in use. In England, upon numerous hospital admissions and deaths, this drug has been already applied.

Ivory wave is available in small packing’s of 200mg to 500 mg and is usually used as bath salts. These are easily available on web world and these cost for £15 a pop. Ivory wave can be snorted or swallowed.

Aiming to raise awareness of Ivory wave, a drug which is rapidly gaining popularity, the author from the Southeast Coast Ambulance Service also said "Whether or not this drug in fact contains illegal ingredients is as yet unclear. The drug's effects are concerning, however, and have been seen in patients in Lothian, Cumbria, Dorset and Essex".

However, the recipe of ivory wave is not yet set, but according to an analysis made it might contain the stimulant methylenedioxypyrovalerone (MDPV) and the anaesthetic lignocaine and can cause initial euphoria with many more illnesses and side effects.
