RESUMO

Abstract Background Therapeutic properties of ibogaine in the treatment of addiction are attracting both clinicians and patients to its use. Since ibogaine is not an authorized medicine, the quality of these products is not always known, increasing the probability of adverse reactions. Objective This study collects different types of iboga-derived samples from treatment providers, vendors and online buyers to analyse their content. Methods Analysis of iboga products (n = 16) was performed using gas chromatography and mass spectrometry methods (GC/MS). Products included Iboga root bark, Total Alkaloids (TA), Purified Total Alkaloids (PTA HCl), ibogaine hydrochloride (ibogaine HCl) and one Voacanga africana root bark. Results The content of ibogaine was highly variable, ranging from 0.6% to 11.2% for products sold as iboga root bark, from 8.2% to 32.9% for products sold as TA, 73.7% for one sample sold as PTA and from 61.5% to 73.4% for products sold as ibogaine HCl. One sample did not show any iboga alkaloids. Other alkaloids and unknown substances were found in almost all samples. Discussion The purity of iboga products is highly variable. These results should be taken into consideration by suppliers and users, especially regarding correct dosing to avoid overdose, as well as potential interactions with other substances.

RESUMO

New psychoactive tryptamines may be a public health risk since they intend to mimic the hallucinogenic effects of regulated psychoactive drugs. Few studies describe uses and clinical effects of unregulated new psychoactive tryptamines. This study aims (1) to explore the presence of tryptamines classified as NPS among the substances delivered for analysis to a harm-reduction organization; (2) to describe the substances found in the samples after analysis; and (3) to compare analytical results of regulated vs. non-regulated tryptamines. Samples delivered and analyzed by gas chromatography-mass spectrometry from 2006 to 2015 were included. A descriptive study of results was conducted. From 25,296 samples that were delivered, 436 were tryptamines; from these 232 (53.21%) were non-regulated. The most delivered non-regulated tryptamine was 4-AcO-DMT. A search of the PubMed database in July 2016 revealed that no studies in humans have ever been carried out with 4-AcO-DMT. Unregulated tryptamines likely contained one unadulterated substance (p ≤ 0.001). The number of samples submitted which contained tryptamines increased during the course of the study, with significant differences in client expectations vs. analysis results between the controlled and uncontrolled groups. There is a need for further research in order to prevent the potential health risks associated with their use.

RESUMO

OBJECTIVE: This paper aims to present results of the analysis of clephedrone (4-CMC), 4-chloroethcathinone (4-CEC), and brephedrone (4-BMC) on recreational drug markets and a systematic review of all the available information concerning these substances. MATERIAL AND METHODS: Samples collected by the drug checking service of the Spanish harm reduction NGO-Energy Control were analyzed and systematic research was conducted. Between June 2014 and October 2016, 1,471 samples with at least one NPS were analyzed, 397 of which contained cathinones. RESULTS: Clephedrone was found in 29 samples, brephedrone in 8, and both were present in 2 samples. 4-Chloroethcathinone was detected in 5 samples. Eleven out of the 47 purchased samples (23.4%) were tested to contain the substance the user expected. Samples received were mainly sold as 3-MMC, MDMA, ketamine, and other cathinones. No literature on the effects or toxicity of these substances was found; the only information available was on internet fora. On many posts, users exhibit concerns about potential toxicity and side effects of using these substances. CONCLUSION: Since the emergence of these substances could prove to be the next step to the cat-and-mouse game existing between drug producers and legislation, further clinical and epidemiological research should be carried out in order to build evidence to support policy for public health issues.

RESUMO

BACKGROUND: The popularization of anonymous markets such as Silk Road is challenging current drug policy and may provide a new context for old issues, such as adulteration of heroin with fentanyl derivatives. The aims of this paper are to report the presence of ocfentanil, a novel, potent, non-controlled fentanyl analog, in samples sold as heroin in the hidden web, and to summarize the effects reported by users. METHODS: In 2015, four samples allegedly bought as heroin in cryptomarkets of the hidden web were sent to Energy Control for analysis. Energy Control is a Spanish harm reduction NGO that offers anonymous drug checking with the purpose of adapting counselling to the specific substances present in the drug and monitor the drug market. Identification was performed by GC/MS and LC/MS/MS. We contacted the submitters of the samples and performed an Internet search to retrieve additional information. RESULTS: One sample contained ocfentanil, caffeine and heroin. Three samples contained the aforementioned substances plus paracetamol. Two out of the four contacted users reported distinct short acting, opioid-like effects. No fora discussion could be found about the effects of ocfentanil, neither web pages nor individuals advertising the substance. CONCLUSION: We report the presence of a new substance detected in the hidden web as an adulterant of heroin, ocfentanil. It has short acting opioid-like effects, roughly the same potency as fentanyl, and can be injected, snorted or smoked. Severe side effects have been associated with its use, including one death. No discussion about this substance could be found in the Internet, which suggests this substance has not been sold as such. Available data about purities of drugs purchased in cryptomarkets suggest that adulteration is not a severe problem and this agrees with users' perceptions. However, this study suggests that adulteration is a real threat not only at the street level, but also for users that buy substances in cryptomarkets, and suggest the need for harm reduction initiatives in this setting.

RESUMO

INTRODUCTION: User surveys indicate that expectations of higher drug purity are a key reason for cryptomarket use. In 2014-2015, Spain's NGO Energy Control conducted a 1-year pilot project to provide a testing service to cryptomarket drug users using the Transnational European Drug Information (TEDI) guidelines. In this paper, we present content and purity data from the trial. METHODS: 219 samples were analyzed by gas chromatography associated with mass spectrometry (GC/MS). Users were asked to report what substance they allegedly purchased. RESULTS: 40 different advertised substances were reported, although 77.6% were common recreational drugs (cocaine, MDMA, amphetamines, LSD, ketamine, cannabis). In 200 samples (91.3%), the main result of analysis matched the advertised substance. Where the advertised compound was detected, purity levels (m±SD) were: cocaine 71.6±19.4%; MDMA (crystal) 88.3±1.4%; MDMA (pills) 133.3±38.4mg; Amphetamine (speed) 51.3±33.9%; LSD 123.6±40.5µg; Cannabis resin THC: 16.5±7.5% CBD: 3.4±1.5%; Ketamine 71.3±38.4%. 39.8% of cocaine samples contained the adulterant levamisole (11.6±8%). No adulterants were found in MDMA and LSD samples. DISCUSSION: The largest collection of test results from drug samples delivered from cryptomarkets are reported in this study. Most substances contained the advertised ingredient and most samples were of high purity. The representativeness of these results is unknown.

RESUMO

OBJECTIVE: The aim of this study was to describe the presence and composition of cathinone derivatives (CDs) in drug samples analyzed at a Drug Testing Service. MATERIAL AND METHODS: Data provided by the Drug Testing Service at Energy Control (a Spanish organization working in risk reduction among recreational drug users) were obtained from samples delivered as, or containing CDs, between January 2010 and June 2012. Specimens were identified by combining thin layer chromatography and gas chromatography associated with mass spectrometry. RESULTS: Two hundred and thirty-seven (3.8%) of the 6199 samples were delivered as, or contained CDs. 22 different CDs were detected, alone or in different combinations. Methylone (24.9%), mephedrone (24.5%), 4-methylethcathinone (9.28%), and methylenedioxypyrovalerone (6.8%) were the most common CDs. These substances were also found in 80 (1.3%) of 6042 samples delivered allegedly containing drugs different from CDs (such as 3,4-methylenedioxy-N-methylamphetamine (MDMA), amphetamines, ketamine…). CONCLUSIONS: Cathinone derivatives were markedly present in the Spanish drug market during the studied period. There is no evidence to conclude that use of CDs will become widespread or relevant for public health, but the phenomenon must be followed, as the potential risks of these new drugs of abuse are substantial.
