  • Transcript

    • 1. The legal highs Dr Ioana Vlad
    • 2. Synthetic / emerging drugs • What are they? • How do patients present? • How do we treat? • What is all the fuss about?
    • 3. Issues - readily available in retail stores and online - cheap - highly attractive packaging - perceived as safe drugs - party pills / herbal highs / legal highs / nutritional supplements - not easily detectable in urine or blood samples
    • 4. Synthetic / emerging drugs • Synthetic cannabinoids • Synthetic cathinones • Novel psychedelics / synthetic LSD
    • 5. Synthetic cannabinoids
    • 6. Synthetic cannabinoids • Usually marketed as incense sticks • Smoked or ingested “with a carrier high in fat content” • Labeled “not for human consumption”
    • 7. Synthetic cannabinoids • • • • • • • Spice K2 Happy Tiger Incense Blueberry spice Purple rush Banana cream nuke Kronic
    • 8. Synthetic cannabinoids ( ~ 460) Naphthoylindoles JWH-018 JWH-081 JWH-250 AM-2201 JWH-073 JWH -200 Cyclohexylphenoles CP-47497 CP 47 CP 497 • structurally different from THC but same effect on cannabinoid receptors
    • 9. Synthetic cannabinoids • 1984 John Huffman University of Clemson (USA) • 2004 “Spice” appeared in London - The Psyche Deli company
    • 10. Advertised effects • Euphoria / relaxation / laughter / feelings of joy
    • 11. Clinical presentations • Agitation / paranoid psychosis • Seizures • Nausea, vomiting • Acute kidney injury • Hypokalaemia / hyperglycaemia • Hyperthermia • SVT / cardiomyopathy / acute LVF / AMI • Hypertension
    • 12. Synthetic cathinones
    • 13. Synthetic cathinones - chemically similar to cathinone found in the khat plant of eastern Africa - manufactured in China - tablets or powder / swallowed, snorted or injected - most common - 3,4 methylenedioxypyrovalerone (MDPV), mephedrone, methylone
    • 14. 3, 4-Methylenedioxypyrovalerone (MDPV) & other synthetic cathinones  effects similar to cocaine / amphetamines / MDMA - sometimes labeled as legal cocaine or legal amphetamines
    • 15. MDPV timeline  Developed in the 1960s for the treatment of chronic fatigue, but abandoned due to abuse and dependence  1969: Boehringer Ingelheim files a patent application for MDPV  2005: MDPV on recreational drugs markets and mentioned on Drugs forum
    • 16. MDPV timeline  2007: first seizure of MDPV as a recreational drug, by customs officials in Germany (shipped from China)  2009: MDPV made illegal in Denmark 2010: UK 2011: USA, Australia
    • 17.  Sold as bath salts / insect repellant / research chemical / plant food  Sold mostly on the internet, but can also be found in adult or herbal shops  Labeled “not for human consumption.”
    • 18.  Red Dove  Blue Silk  Cloud Nine  Ocean Snow  Lunar Wave  Vanilla Sky  Ivory Wave  White Lightning  Scarface  Purple Wave  Star Dust  Hurricane Charlie
    • 19. Advertised effects  Euphoric  Anorectic  Aphrodisiac  Anxiogenic  Increases alertness  Inhibits sleep
    • 20. Advertised effects “ Swim says he finds MDPV a wonderful compund for getting things done, like cleaning the flat, getting long boring e-mails written and sent and working through shitloads of Uni-grade maths at hyperspeed. The lack of euphoria is almost concieved as positive by SWIM as it doesn't distract him from the task at hand." "...lower doses of MDPV produces a clarity of thought far superior to just about every other stimulant I've ever tried."
    • 21. Clinical presentation dopamine-noadrenaline reuptake inhibitors (NDRI) - Agitation / aggression / paranoid delusions with violent behaviour / increased alertness/awareness / insomnia - Headache, confusion, seizures - Movement disorders - bruxism / muscle spasms - Abdominal pain - Rhabdomyolysis, renal failure; hyponatraemia - Tachycardia, hypertension, vasoconstriction – STEMI - Tachyarrhythmias - Hyperthermia
    • 22. MDPV  quick onset  peak effects for 3 - 4 hours  tachycardia, hypertension, and mild stimulation last 6 - 8 hours
    • 23. MDPV’s chemical ‘cousins’  α-pyrrolidinopropiophenone (α-PPP) - detected in Germany in seized "ecstasy" tablets  4'-methyl-α-pyrrolidinopropiophenone (MPPP) - Germany late 1990s / early 2000s  3',4'-methylenedioxy-α-pyrrolidinopropiophenone (MDPPP) - Germany late 1990s / early 2000s - imitation ecstasy
    • 24. Gen 2, 3 etc. of “bath salts” • Naphyrone / O-2482 / naphthylpyrovalerone – “Cosmic Blast” - marketed as a jewelry cleaner – triple reuptake inhibitor (serotonin / noradr / dopamine) – anecdotal reports of prolonged toxicity and severe hyperthermia • Pentedrone, Alpha-PVP, 3,4-DMMC
    • 25. What are the issues with MDPV?
    • 26. What are the issues with MDPV? "MDPV is the most compulsive drug swim has ever done, he just can't stop hitting that pipe, it's worse than fucking crack! He's been at it since 11am, 16 hours ago, and in that time he's done 150mg so far, solely via the pipe, far too much!! He's still got over 300mg left, aargh!!! ...He's not even sure if he's still enjoying it, don't think he is, but still he can't stop hitting that pipe for some reason (though he does know why really, dopamine = reward innit). Bloody strange substance! Any swimer fancy coming round and freeing swim of this bloody pipe?"
    • 27. What are the issues with MDPV? "MDPV is like the bastard with a whip you've got to obey or you get hurt. Then you obey and get hurt even worse. Finally, it's "Thank you sir may I have another... thank you sir, may I have another... thank you sir, may I have another..." and you wonder why you've come to enjoy feeling like shit nearly every waking moment. You vow never to touch MDPV again, then an hour or two after it wears off you find yourself eagerly using MDPV."
    • 28. Novel psychedelics / NBOMe Alexander Shulgin Albert Hofmann
    • 29. Novel psychedelics / NBOMe
    • 30. Novel psychedelics or synthetic LSD  25B-NBOMe / 25I-NBOMe  derivatives of the 2C family of phenethylamine psychedelics  very potent partial agonists 5HT – 2A receptor  snorted or dissolved into a liquid and placed on blotter paper under the tongue
    • 31. Advertised effects  90s – replacement for ecstasy  Colourful hallucinations  Feelings of empathy  Feelings of closeness with others
    • 32. Effects • Aggitation / extreme behaviours • Tahycardia, hypertension • Hyperthermia • Seizures • Metabolic acidosis • Multiorgan failure
    • 33. Effects - onset ~15 min - may last 6-10 hours - active at very low doses
    • 34. Treatment - Supportive care - benzodiazepines for agitation, seizures, tachycardia, and hypertension - Significant hyperthemia may require passive or active cooling - Consider checking electrolytes, renal and liver function tests, cardiac markers, CK - Observe until resolution of abnormal vital signs, vomiting, and psychiatric symptoms
    • 35. Legislation issues - June 2011 – synthetic cannabinoids banned in WA / QLD / VIC and then federal - October 2011 – MDPV banned in USA and most European countries - February 2012 – WA bans MDPV The problem: drugs could only be added to the list once identified
    • 36. DMEC Methedrone Ethedrone 3-MOMC 2-FMC 2-FEC 3-FMC 3-FEC 3-CMC 3-BMC Flephedrone 4-FEC Brephedrone FMMC 2,5-DMOMC bk-MDA 2,3-MDMC Methylone Ethylone O-2384 α-PVP (O-2387) 4-MeMABP 4-Me-NEB 4-Methoxybuphedrone Butylone Eutylone BMDB bk-DMBDB 5-Methylmethylone 5-Methylethylone 2-Methylbutylone 5-Methylbutylone Pentylone MMP MEP bk-Methiopropamine αPhthalimidopropiophen one α-PPP α-PBP EDMC 3,4-DMMC
    • 37. • Urine drug screens will not pick them up • Blood tests available – Expensive – Only for identified structures
    • 38. Legislation issues - Sept 2013 – NSW law banning “manufacture, supply and advertising of psychoactive substances (schedule 9)”
    • 39. Take home messages - drugs of abuse are forever changing - manipulation of basic chemical structures to avoid legal ramifications - the classes of drugs more important than names - effects: psychoactive and sympathomimetic - symptomatic management -BZDs are a useful adjunct
