3 Amphetamines Ecstasy - MDMA The rela2ve amount of metamphetamine has the recent years been increasing in Norway1, and since 2009 it became the most common; Complex drug with many ac2ons Blokkerer reopptak av dopamin og serotonin i synapser i CNS Hemmer produksjonen av serotonin S2mulerer sympa2kus The three Es: Energi Empa2 Eufori 1Seizures.

4 Ecstasy psykiske senvirkninger NPS - Background and defini@on (I) Senker serotoninnivået i CNS Personlighetsendringer Schizofrene trekk Kogni2v dysfunksjon Læreproblemer Nedsa> oppmerksomhet Nedsa> hukommelse Either synte2c, semi- synte2c or naturally occuring substances intended to illicit a psychoac@ve response, being either s@mulant, hallucinogenic, seda@ve or a combina@on of these There are many chemical similari2es between legal highs and endogenous neurotransmi>ers, specifically serotonin, norepinephrine and dopamine 1 Several classes of legal highs have been modeled on exis@ng and controlled drugs of abuse because of ease in synthesizing (esp. phenylethylamine (amphetamine), cocaine, phencyclidine and tryptamine classes). 1 1 Gibbons S. Clinical Toxicology (2012), 50, Knut Erik Hovda, European Society of Emergency Medicine, Turkey NPS - Background and defini@on (II) Marketed as not for human consump2on, plant food, bath salts or even pond cleaner Significant variability in the contents of novel psychoac2ve substances 1,2,3 Typically appearing in smaller groups first (olen clubbers etc) increasing # of users Informa@on spread especially through internet NPS - Bakgrunn og definisjon (III) Vanligvis utøres ikke ru2nemessig screening (blod- eller urinprøver) e>ersom det olest ikke vil påvirke den aku>e behandlingen Drama2sk økning i 2lgjengelighet og bruk de siste årene: : 164 nye psykoak2ve stoffer ble formelt meldt inn gjennom systemet for 2dlig varsling (EWS) 1. 1 Ramsey J et al (2010).

Below is the grouping used by EMCDDA: 1. Phenetylamines 2. Tryptamines 3. Piperazines 4. Cathinones 5. Synte2c cannabinoids 6. Other substances 1. Phenetylamines Effects: s2mulant, entactogenic or hallucinogenic effects The most common group un2l 2010 Examples: amphetamine, methamphetamine, PMA, PMMA, MDMA, MBDB, MDEA, mescaline, 2C- E, Benzofurans and benzodifuranes (e.g. BromoDragonfly, benzo fury) Knut Erik Hovda, European Society of Emergency Medicine, Turkey Knut Erik Hovda, European Society of Emergency Medicine, Turkey

5 PMMA (I) PMMA (II) PMMA; Para- methoxy- methyl- amphetamine Sudden outbreak in Norway in 2010, classified as a narco2c in November reported mortali2es1 + found in persons driving under the influence during 14 months Why PMMA? Possibly because of one of the precursors in the produc2on of amphetamine & metamphetamine became illegal in Russia1 Why this high mortality with PMMA? Olen sold as ecstasy or amphetamine, but with a slower onset of symptoms. Users olen think it is weak drugs and use more to gain effect. Norway; locally produced??? 1Vevelstad M et al.

NAACT 2011 Washington DC Alfa-Methyl-Tryptamin 2. Tryptamines Effects: predominantly hallucinogenic effects Examples: α- Methyltryptamine (AMT), dimethyltryptamine (DMT), psilocin, psilocybin, LSD, 4- OH- metyletyltryptamin (4- OH- MET) Psilocybin AMT 3. Piperazines Effects: s2mulants Examples: 1- (3- chlorophenyl)piperazine (mcpp), 1- benzylpiperazine (BZP), A2, TFMPP, Beans (Happy Popper) Serotonin 4. Cathinones Effects: s2mulants, olen also hallucinogenic effects The second most common group Bath salts (US) or plant food (Europe) olen refers to this group Examples: mephedrone, flefedron, efedron, methylone, methylene dioxy- pyruvalone (MDPV), methcathinone 5

6 Mephedrone 5. cannabinoids/thc- analogues/ Spice The first cathinone to be formally risk- assessed Effects: hallucinogenic, seda2ve and depressant effects (some2mes also s2mulant proper2es) Higher affinity for the CB1 receptor compared to classical cannabinoids Increasing fastest along with the cathinones now most common Examples: JWH- 011, JWH- 018, JWH- 019, JWH- 122, JWH- 133, JWH- 250, JWH- 251, Remix, Space Sta2on, Rainbow in Heaven, Black Widow, Double Dutch, Jamaican Spirit, Jamaican Potpurri, DJ, Bonzai Citrus, XXXL, Package 69, Aroma2c Potpurri The first report on Mephedrone (female 18yrs) died in Stockholm December Since that appearantly among the most frequently used novel psychoac2ve drug in various recrea2onal se ngs; A night- club study showing 53% last month use and 41% use on the night of the survey2 Internet surveys from UK clubbers: approx 40% life2me- use in 20103, and 61% in Possible decrease with change in legisla2on; possible change towards similar products ( research chemicals / legal alterna2ves to mephedrone ) 1Gustavsson D, Escher C.

Effects: Large varia2ons; depending on the substance Examples: plant derived and synte2c psycoac2ve substances (indanes (e.g. MDAI), narco2c analge2cs, synthe2c cocaine deriva2ves, ketamine- and phencyclidine deriva2ves), and medicinal products Originally developed as an anesthe2c in the 60 s Used as a recrea2onal drug for at least three decades Very easy to make from easily available ingredients Stable, high- frequency use in many countries; Example - Norway; number of seizures (rela2vely & total), but small part of the total number of seizures Oslo; 5th most common main agent for all tox. hospitaliza2ons in and Withdrawals can be severe BZD drug of choice.

8 Data om akuie forgijninger med NPS Conclusion Trends in Europe; (Nye) rusmidler er vanlige Systema2ske data er 2lgjengelige for: Prevalensen av bruk Beslagstall Bruken av rusklinikker for problem drug use Rusrelaterte dødsfall Det finnes ingen systema5ske data om aku> toksisitet for disse rusmidlene Conclusion (II) Increasing number of substances; difficult to keep up Increasing # of reports on severe toxicity and mortali2es Difficult to be ahead of 2me ; how do we collate data regarding Clinical toxicology? Effects and side- effects are highly varying and unpredictable Na2onal varia2ons, but the new recrea2onal drugs respect no borders Fast- track varia2ons in panorama depending on legisla2on, availability of substances/precursors etc. Impuri2es might compose big user- and diagnos2c problems Anbefalt liieratur May encompass various unthinkable problems..
