2 The EU Early Warning System on NPS since 1997 Reporting - forensic analysis Targeted research Open source information

3 The EU Early Warning System on NPS Total: 527 substances under monitoring; 60% of which since synthetic cathinones monitored by the EWS 31 new in 2014; 18 new in methylone

6 Number of seizures of synthetic cathinones(nsz) NSz and quantity seized (powders), NSz and proportion of seizures by substance, seizures amounting to more than 1.1 tonnes in 2013

7 Number of seizures of synthetic cathinones(nsz) NSz and quantity seized (powders), NSz and proportion of seizures by substance, 2013 Many of them are used as replacements for stimulants. Typically supplied as a powder; but also in tablet, capsule and liquid form. They are soluble in water and the powder can be dissolved for oral use or intravenous and subcutaneous injection.

12 Pharmacology considerable diversity of pharmacology within the group of cathinones Cathinone Methamphetamine-like cathinones Methcathinone Schedule I Schedule I Toxicity similar to amphetamine, including: hypertension, hyperthermia, euphoria, locomotor activation, and hallucinations following higher or repeated doses.

13 Pharmacology considerable diversity of pharmacology within the group of cathinones Cocaine/MDMA cathinones 4-methylmethcathinone 4-MMC, mephedrone EU risk assessment, 2010 Schedule II (2015) Empathogen/stimulant-type effects; dependence potential Subjective effects similar to those of cocaine but also MDMA It has been reported to produce strong craving in humans and to be more addictive than cocaine. Acute toxicity: sympathomimetic toxidrome, agitation, vomiting, psychosis, chest pain, seizures, insomnia Liechti, M.E. Swiss Med Wkly. 2015;145:w

17 MDPV MDPV has potent cocaine-like stimulant properties. MDPV was reported in seizures in 27 MS, Norway and Turkey. In excess of seizures were reported, with two countries reporting >1000 seizures each (UK, FI). The total amount of powder seized was over 200 kg. EMCDDA monitoring of Internet suppliers and retailers selling MDPV identified more than 20 companies that may be based within the European Union and China, offering up to multi-kilogram quantities of the substance. A total of 525 non-fatal intoxications associated with MDPV have been reported by 8 MS. Key adverse effects associated with MDPV intoxication frequently reported in clinical case reports include: paranoid psychosis, hypertension, tachycardia, diaphoresis, severe agitation, auditory and visual hallucinations, profound anxiety, hyperthermia, violent outbursts and multiple organ dysfunction. There have been a total of 108 deaths associated with MDPV reported by 8 MS and Norway in which MDPV has been detected in biological samples.

18 α-pvp α-pvp, similarly to MDPV, is a potent psychostimulant with abuse liability and dependence potential. α-pvp has been available in the EU since at least February 2011 and has been detected in 28 MS, Turkey and Norway. In excess of 5200 seizures were reported with 8 countries reporting > 100 seizures each (UK, FI, SK, SE, IE, HU & TK). The total amount of powder seized was over 750 kg. It has been seized as a powder, but other forms including tablets have been detected. Multi-kilogram quantities of α-pvp have been seized at EU borders which usually originate from China. This includes the seizure of more than 280 kg in Illicit production and tableting sites have also been seized. α-pvp is sold as a research chemical online and is available in wholesale and consumer amounts. 140 serious adverse events associated with α-pvp have been reported by 9 MS. This includes acute intoxications requiring hospitalisation and more than 100 deaths; in at least 23 of these deaths α-pvp was the cause of death or contributed to it. 18

19 Conclusions Synthetic cathinones have carved a space in the illicit stimulants market. The injection of synthetic cathinones by high risk drug users has been reported in a number of countries in Europe. Injecting cathinones carries public health risks of bacterial infections and transmission of blood-borne viruses such as human immunodeficiency virus, hepatitis C virus and hepatitis B virus. Data suggests that injection of these substances lead to different treatment needs than illicit drugs (more frequent injecting, sharing of injecting equipment and psychosis). Research needed (pharmacological & toxicological studies). 19
