The government's official drug advisers are to look at banning a synthetic chemical marketed as NRG-1 that they dread will turn into the following favorite legal high when mephedrone is banned.

The Advisory Council for the Incorrect use of Medications is also to launch an urgent investigation to the whole range of legitimate highs now readily available in Britain. It's going to look at setting up an earlier warning process to discover new medicines that emerge for the marketplace and rapidly restrict their spread.

The ACMD's chair, Professor Les Iversen, has also made apparent to the home secretary, Alan Johnson, that their recommendation to ban mephedrone, the imitation amphetamine, being a class B medication does not rest on its feasible association to 25 deaths in England and Scotland.

In its statement published this month on mephedrone and connected compounds, the ACMD also cited the threat of dependence for the reason that of re-dosing or "fiending", the involvement of organised crime groups in its supply, its widespread and sudden reputation amongst youths, and its price – £10 a gram – as causes for that ban.

Iversen has said the home secretary how the ACMD will issue suggestion on one more legal high promoted as NRG-1. The chemical description of the drug may be the "napthyl analogue of pyrovalerone". Pyrovalerone is currently a banned class C drug in Britain. It is broadly prescribed in France as an appetite suppressant. The south-east Asian chemists who have flooded the market with mephedrone and with Spice, a herbal high very similar to cannabis which was banned last month, have synthesised this new legitimate choice, suppliers said.

A British supplier located in Belgium was quoted by Sky News as saying NRG-1 was staying marketed like a mephedrone replacement and could price as tiny as 25p a hit.

The earlier warning procedure to determine emerging harmful drugs will consist of analysis of examination of "drug amnesty bins" in clubs. A Home Office spokesman mentioned: "We keep on to keep an eye on the emergence and harms of newlegal highs to ensure that our approach is proportionate and proof dependent."

The ACMD's mephedrone report acknowledges the only facts so far that it could kill rests to the inescapable fact it has been discovered existing at seven out of 18 postmortems into suspected deaths in England. "That mephedrone may possibly are actually included inside a death cannot be confirmed till the applicable coroner or procurator fiscal has concluded his inquest," it says.
