bath salts' and other emerging designer drugs,[url=http://www.chanel-handbags.us@#$%&/]chanel bag[/url]
DENVER,[url=http://www.raybansunglassesoutleta@#$%&/]@#$%& sunglasses cheap[/url], Aug. 30,[url=http://www.gucci-outlet.us@#$%&/]gucci backpack[/url], 2011 Scientists today reported development of much needed new tests to help cope with a wave of deaths, emergency room visits and other problems from a new genre of designer drugs sold legally in stores and online that mimic the effects of cocaine, ecstasy and marijuana. They spoke at the 242nd National Meeting Exposition of the American Chemical Society (ACS), being held here this week.
The reports,[url=http://www.lululemonoutlet-canada.ca/]lululemon outlet[/url], among more than 7,[url=http://www.canadagoosejacketsoutlet.ca/]@#$%& jackets[/url],500 on the ACS agenda,[url=http://www.katespadeoutlethandbags@#$%&/]kate spade@#$%&[/url], focus on drugs sold as "bath salts,[url=http://www.canadagoose.cc/]@#$%& jackets[/url]," "plant food,[url=http://www.poloralphlaurenoutletonline.us@#$%&/]cheap @#$%& polo shirts[/url]," "incense" and other products with colorful names, such as "Ivory Wave,[url=http://www.abercrombieand-fitch@#$%&/]abercrombiekids@#$%&[/url]," "Red Dove" and "legal marijuana." They provide users with a high,[url=http://www.northface-jackets.us@#$%&/]north face endurance challenge[/url], but many have not yet been made illegal and are undetectable with current drug tests. researcher discussed the challenges facing law enforcement and policy makers in regulating synthetic versions of marijuana.
"With the new method,[url=http://www.juicycoutureoutlethandbags.in.net/]juicycouture@#$%&[/url], we could work backwards and trace the substances back to the starting materials," said Sutcliffe. IRMS measures the relative amounts of an element's different forms,[url=http://www.lunetterayban-pas-cher.fr/]ray-ban[/url], or isotopic ratio. "This method was successful because the isotopic ratio of the starting material is transferred like a fingerprint through the synthesis,[url=http://www.instylerionicstyler.us@#$%&/]instyler wet to dry[/url]," he explained. These products are not in the supermarket soap aisle they are sold on the Internet,[url=http://www.moncler-outlet.it/]moncler sito ufficiale[/url], on the street and in stores that sell drug paraphernalia. They are sold in small individual bags for as low as $20 each for the real purpose of providing a cheap,[url=http://www.ferragamo-shoes-outlet@#$%&/]ferragamo belt[/url], legal high. Usually,[url=http://www.nikefreerun.fr/]free run @#$%&[/url], that would mean that these compounds (and derivatives thereof) would be illegal in those countries too,[url=http://www.@#$%&--trainers.co.uk/]trainers uk[/url], but because the bath salts are labeled "not for human consumption,[url=http://www.ugg-australia.it/]ugg australia[/url]," they get around this restriction and other legislation governing the supply of medicines for human use. However,[url=http://www.truereligionjean.cc/]true religion outlet store[/url], Florida and Louisiana two hotspots of bath salts abuse specifically banned the substances. soil, said Sutcliffe. The new method provides law enforcement with a tool to track down these bath salts manufacturers.
In previous work, Sutcliffe developed the first pure reference standard for mephedrone,[url=http://www.@#$%&-airmax2u@#$%&/]@#$%& air max 95[/url], as well as the first reliable liquid chromatography test for the substance, which could be easily run in a typical law enforcement lab. The team is also developing a color change test kit for mephedrone, which he estimates may be available by the end of the year. synthetic cannabinoids marketed as incense, a spice product or "legal marijuana" that give a high similar to marijuana without showing up in conventional drug tests.
"We can detect synthetic cannabinoids with modern analytical chemistry techniques, such as liquid or gas chromatography coupled to mass spectrometry, but these assays are too expensive for the 5,000 10,000 urine samples that most drug testing labs receive each day," said Lantz. Most labs screen for drugs with less expensive antibody assays, but because the structures of these substances are so dissimilar, different antibodies would likely be required for many of them, driving up the cost of a more comprehensive test. poison control centers,[url=http://www.longchamphandbags.us@#$%&/]longchamp bags[/url], up to 2,863 compared to only 14 in 2009. Drug Enforcement Agency (DEA) banned only five of those. A handful of states,[url=http://www.cheap-michaelkors.us@#$%&/]michael kors flip flops[/url], such as Washington, Georgia and Colorado, banned five of them,[url=http://www.marcjacobshandbagsoutlet.net/]marc jacobs daisy[/url], but they are not always the same five that the DEA banned. "The states banned several specific compounds without a particular basis for their choices," Lantz pointed out.
Colorado recently passed a law banning any substance that binds to a cannabinoid receptor in the human body. Congress. With more than 163,000 members, ACS is the world's largest scientific society and a global leader in providing access to chemistry related research through its multiple databases, peer reviewed journals and scientific conferences.
The increase in the global abuse of synthetic cathinones has given rise to significant legal and analytical challenges in their identification and quantification thus rapid methods of testing (especially in the field) are urgently required. This paper presents synthesis; characterisation; validated presumptive and quantitative methods for these substances (both in pure and adulterated samples) and a rapid,[url=http://www.oakleysunglasses-outletcheap@#$%&/]oakley si[/url], novel NMR screening technique for street samples containing components which cannot normally be detected using standard chromatographic methods.
Dr. Lantz:
There is no end to human ingenuity. Unfortunately, this phrase even provides to be true when it comes to methods and means of getting high. Synthetic Cannabinoids,[url=http://www.oakleyvaultsunglasses.us@#$%&/]fake oakley[/url], such as JWH 018 which is only one of many such substances (which is currently marketed as K2), and other substances such as Methylone (MDPV) and Mephedrone (which is currently marketed as "Bath Salts" or "Plant Food" respectively) present unique analytical chemistry challenges from a chromatographic point of view. Related challenges in terms of quantitation of these substances still exist. In the rush to make illegal and prosecute the possession and use of these substances, errors related the qualitative and quantitative reporting of these compounds can occur. This presentation will examine these challenges that exist and what lies ahead.
