Following the initial popularity of mephedrone (4-methylmethcathinone) there has been a stream of new recreational drugs entering the global market. The lack of clinical studies on the effects and toxicity of these drugs has made interpretation of toxicological findings difficult. In an attempt to assist in a better understanding of the extent of their use and the fatalities that have been linked to these compounds we present our collated findings in post-mortem and criminal casework where these have been detected and/or implicated. Between January 2010 and December 2012 we have detected new psychoactive substances (NPS) in 203 cases, with 120 cases in 2012 alone. The drugs detected in in life or post-mortem blood and urine are, in order of decreasing frequency; mephedrone, 4-methylethcathinone, BZP, MDPV, TFMPP, methoxetamine, 4-fluoromethcathinone, 4-methylamphetamine, PMA, methylone, PMMA, naphyrone, alpha-methyltryptamine, butylone, MDAI, desoxypipradrol, D2PM, MPA, synthetic cannabinoids, 2-AI, 5-IAI, 5-MeODALT, MDPBP, 5/6-APB, pentedrone and pentylone. Other drugs or alcohol were detected in 84% of the cases including other NPS and in fatalities it should be noted that alternative causes of death (including mechanical suicide, accidental death and non-psychoactive drug overdose) accounted for the majority. Related to this was that of all fatalities involving cathinones, 41% of these were hangings or other mechanical suicides, this was a higher proportion than seen with other drugs found in such cases. The presence of multiple NPS and/or other stimulants was a particular feature in various cases, however, of the drug deaths only 7% solely involved NPS. Across all case types and including some cases investigated in 2013, NPS concentrations showed a wide range but these and selected cases are presented to assist toxicological interpretation in future cases.
