Naphyrone, also known as O-2482 and naphthylpyrovalerone,〔 〕 is a drug derived from pyrovalerone that acts as a triple reuptake inhibitor, producing stimulant effects and has been reported as a novel designer drug. No safety or toxicity data is available on the drug. The drug has been marketed under the name NRG-1, although only a minority of samples of substances sold under this name have been found to actually contain naphyrone, and even samples that proved to contain genuine β-naphyrone were in some cases also found to contain the 1-naphthyl isomer α-naphyrone in varying proportions, further confusing the reported effects profile. ==Use in the United Kingdom== Naphyrone emerged as a new legal high in the United Kingdom only months after the ban of similar drug mephedrone (which was also a cathinone derivative). Until July 2010 the substance was not controlled by the Misuse of Drugs Act 1971 and was therefore not illegal for someone to possess. The Medicines Act prevented naphyrone from being sold for human consumption, and therefore it was sometimes sold as 'pond cleaner' or as another substance not normally consumed by humans. In response to this emerging trend of new designer drugs, Home Office Minister James Brokenshire said, "action to address the issue of emerging legal highs coming on to the market is a priority for the government." A study by researchers at Liverpool John Moores University found that only one out of ten products labelled as "NRG-1" actually contained naphyrone when they were subjected to laboratory analysis. Compounds found in products labelled NRG-1 included MDPV, flephedrone, mephedrone, butylone and caffeine, one product tested was inorganic in composition.〔 In the case of an individual possessing a product labelled NRG-1 that contains MDPV or other illegal substances, they are in possession of a controlled substance. On 12 July 2010, the Home Office announced that naphyrone had been banned and made a Class B drug, following a report from the Advisory Council on the Misuse of Drugs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Naphyrone」の詳細全文を読む スポンサード リンク
