Brussels, 01/1202014 (Agence Europe) - The European Commission proposed on Monday 1 December to ban two harmful new psychoactive substances, which have caused dozens of deaths in the EU over the last few years. One of the substances, 4,4'-DMAR, is a stimulant, like ecstasy, while the other, MT-45, is a potent opioid, like morphine. The proposals, which will have to be approved by qualified majority in Council, seek to ban the manufacture and the marketing of the two new psychoactive substances, which have caused serious concern in the EU. There have been 31 deaths associated with 4,4'-DMAR recorded in three member states over a period of approximately one year. A total of 28 deaths associated with MT-45 have been reported since it was detected in the EU in October 2013. (LC)
