Since the beginning of January 2018, we have tested a number of substances of particular health concern. In addition to a large number of amphetamine samples laced with caffeine, many samples submitted as alleged ecstasy contained high to very high levels of the active ingredient MDMA. In one sample submitted as an unknown substance, the new psychoactive substances 4-chloro-alpha-PVP (4Cl-PVP, 4-chloro-alpha-pyrrolidinovalerophenone) and N-ethylhexedrone (NEH) was identified. An alleged cocaine sample contained cocaine, amphetamine, caffeine and the two new psychoactive substances N-ethylhexedrone (NEH) and MPHP (4′-methyl-α-pyrrolidinohexiophenone).
