A bag of Spice

Synthetic cannabis is a herbal and chemical product which mimics the effects of cannabis. It is best known by the brand names K2[1] and Spice[2]. When synthetic cannabis products first went on sale it was thought that they achieved an effect through a mixture of legal herbs. Laboratory analysis in 2008 showed this was not the case and that they in fact contained synthetic cannabinoids which act on the body in a similar way to cannabinoids naturally found in cannabis, such as THC. Synthetic cannabinoids, including cannabicyclohexanol, JWH-018, JWH-073, and HU-210, are used in an attempt to avoid the laws which make cannabis illegal, making synthetic cannabis a designer drug. It has been sold under various brand names, online, in head shops and at some gas stations. It is marketed as an incense or "herbal smoking blend", but the products are usually smoked by users[citation needed]. Although synthetic cannabis does not produce positive results in drug tests for cannabis, it is possible to detect its metabolites in human urine. The synthetic cannabinoids contained in synthetic cannabis products have been made illegal in many European countries, but remain legal under federal law in the USA and Canada. Several US states have made it illegal under state law.

History

According to the Psychonaut Web Mapping Research Project, synthetic cannabis products, sold under the brand name Spice first appeared in Europe in 2004.[3] The brand "Spice" was released in 2004 by the now dormant company The Psyche Deli in London, UK. In 2006 the brand gained popularity. According to the Financial Times the assets of The Psyche Deli rose from £65,000 in 2006 to £899,000 in 2007. [4] The EMCDDA reported in 2009 that ‘Spice’ products were identified in 21 of the 30 participating countries. Because 'Spice' was the dominant brand until 2009, the competing brands that started to appear from 2008 on, were also dubbed 'Spice'. Spice can therefore relate to both the brand 'Spice', as to all herbal blends with synthetic cannabinoids added. A survey of readers of Mixmag in the UK in 2009, found that one in eight respondents had used synthetic cannabis, compared to 85% who had used cannabis.[5]

Ingredients

Synthetic cannabis is claimed by the manufacturers to contain a mixture of traditionally used medicinal herbs, each of which supposedly produces mild effects with the overall blend resulting in the cannabis-like intoxication produced by the product. Herbs listed on the packaging of Spice include Canavalia maritima, Nymphaea caerulea, Scutellaria nana, Pedicularis densiflora, Leonotis leonurus, Zornia latifolia, Nelumbo nucifera and Leonurus sibiricus. However, when the product was analysed by laboratories in Germany and elsewhere, it was found that many of the characteristic "fingerprint" molecules expected to be present from the claimed plant ingredients were not present. There were also large amounts of synthetic tocopherol present. This suggested that the actual ingredients might not be the same as what was listed on the packet, and a German government risk assessment of the product conducted in November 2008 concluded that it was unclear what the actual plant ingredients were, where the synthetic tocopherol had come from, and whether the subjective cannabis-like effects were actually produced by any of the claimed plant ingredients or instead might possibly be caused by a synthetic cannabinoid drug. Upon further analysis it was reported in a German toxicology report that there were some harmful effects of Spice.[6]

Synthetic cannabinoid ingredients

In January 2009, researchers at the University of Freiburg in Germany announced that an active substance in Spice was an undisclosed analogue of the synthetic cannabinoid CP 47,497.[7] Later that month, CP 47,497 along with its dimethylhexyl, dimethyloctyl and dimethylnonyl homologues, were added to the German controlled drug schedules.[8][9] In May the analogue of CP 47,497 was named cannabicyclohexanol.[10]

In July 2010, it was announced that JWH-018 is one of the active components in at least three versions of Spice, which had been sold in a number of countries around the world since 2002, often marketed as incense.[11][12][13][14] Another potent synthetic cannabinoid, HU-210, has been reported to have been found in Spice seized by U.S. Customs and Border Protection.[15] An analysis of samples acquired four weeks after the German prohibition of JWH-018 took place found that the compound had been replaced with JWH-073.[16]

Different ratios of JWH-018 and CP 47,497 and their analogues have been found in different brands of synthetic cannabis[17] and manufacturers constantly change the composition of their products.[18] The amount of JWH-018 in Spice has been found to vary from 0.2% to 3%.[19]

Safety

No official studies have been conducted on its effects on humans.[23] Though its effects are not well documented, extremely large doses may cause negative effects that are generally not noted in marijuana users, such as increased agitation and vomiting.[24] Professor John W. Huffman who first synthesised many of the cannabinoids used in synthetic cannabis is quoted as saying, "People who use it are idiots"[23] and that "It's like playing Russian roulette. You don't know what it's going to do to you."[25] A three gram package of Spice is said by one study, to have the same health effects on the lungs as a packet of cigarettes, although no conclusive evidence of this exists outside of the study.[6] A user who consumed 3 g of Spice Gold every day for several months showed withdrawal symptoms, similar to those associated with withdrawing from the use of narcotics. Doctors treating the user also noted that his use of the product showed signs associated with addiction.[26] One case has been reported where a user, who had previously suffered from cannabis induced recurrent psychotic episodes, suffered reactivation of their symptoms after using Spice. Psychiatrists treating him have suggested that the lack of an antipsychotic chemical, similar to cannabidiol found in natural cannabis, may make synthetic cannabis more likely to induce psychosis than natural cannabis.[27]

Drug testing

Spice does not cause a positive drug test for cannabis or other illegal drugs using GC-MS-screening with library search, multi-target screening by LC-MS/MS, or immunological screening procedures.[17][26] A study has been conducted into the detection of metabolites of JWH-018 in urine, the metabolites are mainly conjugates with glucuronic acid and can be reliably detected by GC–MS/MS and LC–MS/MS.[28]

Legal status

Europe

Austria
The Austrian Ministry of Health announced on 18 December 2008 that Spice would be controlled under Paragraph 78 of their drug law on the grounds that it contains an active substance which affects the functions of the body, and the legality of JWH-018 is under review.[29][30][31]
Germany
JWH-018, CP 47,497 and the C6, C8 and C9 homologues of CP 47,497 are illegal in Germany since 22 January 2009.[9][32]
Finland
Spice blends are classified as a medicine in Finland and therefore it is illegal to order them without a prescription. In practice it is not possible to get a prescription.[citation needed]
France
JWH-018, CP 47,497 (and its homologues) and HU-210 were all made illegal in France on 24 February 2009.[33]
Ireland
From June 2010, JWH-018, along with a variety of other designer drugs are illegal.[34]
Latvia
JWH-018, JWH-073, CP 47,497 (and its homologues) and HU-210 are all banned in Latvia as well as leonotis leonurus.[35]
Poland
JWH-018 and many of the herbs mentioned on the ingredient lists of Spice and similar preparations were made illegal in May 2009. The bill was passed by Polish Sejm,[36][37] Polish Senat[38] and was signed by the President.[39]
Romania
Spice was made illegal in Romania on 15 February 2010.[40]
Russia
On April 9, 2009, the Chief Medical Officer of the Russian Federation issued a resolution on reinforcing control over the sales of smoking blends. These blends, marketed under the trade names AM-HI-CO, Dream, Spice (Gold, Diamond), Zoom, Ex-ses, Yucatán Fire and others have been declared to contain Salvia divinorum, Hawaiian Wood Rose and Blue Lotus and are prohibited to be sold. These substances have been found to have "psychotropic, narcotic effects, contain poisonous components and represent potential threat for humans". The resolution does not mention JWH-018 or other synthetic cannabinoids.[41] On January 14, 2010, the Russian government issued a statement including 23 synthetic cannabinoids found in smoking blends Hawaiian Rose and Blue Lotus on the list of prohibited narcotic and psychotropic substances. Thus, all of these plants and compounds are now illegal in the Russian Federation.[42]
Slovak Republic
Spice is legal in the Slovak Republic. The National Anti-Drug Unit is considering adding it to the list of controlled substances.[43] The latest anti-drug law version (468/2009) valid since January 2010 still does not mention active compounds of Spice.[44]
Sweden
CP 47,497-C6, CP 47,497-C7, CP 47,497-C8, CP 47,497-C9, JWH-018, JWH-073 and HU-210 were all made illegal in Sweden on 15 September 2009. The bill was accepted on 30 July 2009 and was put in effect on 15 September 2009.[45]
Switzerland
Spice has been banned in Switzerland.[46]
United Kingdom
Spice was legal in the United Kingdom until December 2009, when it was classified as a Class B drug.[47]

South America

Chile
The Chilean Ministry of Health on April 24, 2009 declared the sale of synthetic cannabis to be illegal.[48]

Asia

South Korea
South Korea officially added JWH-018, CP 47,497 and HU-210 to the controlled substance list on July 1, 2009, effectively making these chemicals illegal.[49]
Japan
Japan has banned JWH-018, CP 47, 497, and homologues, and HU-210 since Oct. 2009[citation needed]

Australasia

New Zealand
Spice is currently legal in New Zealand.[50]

North America

Spice is currently legal in Canada. Health Canada is debating on the subject.[51][52] According to present status there are no Bills, nor amendments to such requesting the control of this substance all forms of JWHxxx are still uncontrolled in Canada as of June 3, 2010.[53]

United States

See also: JWH-018#United States

Some forms of synthetic cannabis (HU-210) are currently scheduled in the USA under federal law while others are not (JWH-073).[54][55][56] The Drug Enforcement Agency considers it to be a "drug of concern".[57] Several states have passed acts making it illegal under state law however, including Kansas in March 2010,[58] Georgia and Alabama in May 2010,[59][60] Tennessee and Missouri in July 2010,[61][62] Louisiana in August 2010, and Mississippi in September 2010. An emergency order was passed in Arkansas in July 2010, banning the sale of synthetic cannabis.[63] According to the National Conference of State Legislatures, several other states are also considering legislation, including Michigan, New Jersey, New York, Indiana, and Ohio.[62] Illinois passed a law on July 27, 2010 banning all synthetic cannabinoids that goes into effect January 1, 2011.[64]

Following cases in Okinawa and Japan involving the use of synthetic cannabis by Navy Army and Marine personnel resulted in the official banning of it,[65] a punitive general order issued on January 4, 2010 by the Commander Marine Corps Forces, Pacific prohibits the actual or attempted possession, use, sale, distribution or manufacture of synthetic cannabis as well as any derivative, analogue or variant of it.[66] On June 8, 2010, the U.S. Air Force issued a memorandum that banned the possession and use of Spice, or any other mood-altering substance, among its service members.[67]
