Abstract
Already in early 2000s, concerns have been growing in the EU about increasing use of cocaine and it is estimated that below 1 % of the population administer the drug by smoking crack cocaine. New available data suggests an increase in the use of crack cocaine and an increase in the number of crack cocaine users entering treatment has been reported in several European countries. Robust estimations of crack cocaine use are however not available yet. The use of crack cocaine has long been associated with severe adverse socio-economic conditions as well as mental health problems, such as suicide ideation and depression. The aim of this study was to assess spatial trends in population-normalized mass loads of crack cocaine biomarkers (i.e., anhydroecgonine and anhydroecgonine methyl ester) in 13 European cities in six countries (the Netherlands, Belgium, Ireland, Portugal, Spain and Italy). Furthermore, temporal trends over a five-year period were evaluated through the analysis of historic samples collected in the Netherlands. Finally, the stability of the crack cocaine biomarkers in wastewater was investigated through batch experiments. The samples were analyzed with a new developed and validated hydrophilic interaction liquid chromatography coupled to mass spectrometry method. Targeted crack cocaine biomarkers were found in all cities. Also, crack cocaine biomarker was detected in wastewater from 2017 to 2021 in the Netherlands, but no significance between the years were found. With respect to biomarker in-sample stability, AEME was found to be stable in wastewater. This study assessed crack cocaine use for the first time on a broad scale, both temporal and in cities across Europe, with wastewater-based epidemiology and it shows the importance of wastewater analysis to monitor community loads of crack cocaine use.

Abstract
BACKGROUND Maladaptive decision-making is assumed to be a core feature of cocaine addiction. Indeed, numerous studies have reported deficits in non-social decision-making tasks and reward-related impulsivity in dependent cocaine users. However, social decision-making has not been examined in cocaine users yet. Moreover, it is unknown if even recreational and non-dependent cocaine use is linked to decision-making deficits. Therefore, we investigated whether recreational and dependent cocaine users exhibit alterations in social and non-social decision-making. METHOD The performance of healthy controls (n = 68), recreational cocaine users (n = 68) and dependent cocaine users (n = 30) in classical decision-making paradigms (Iowa Gambling Task, Delay Discounting) and in social interaction paradigms (Distribution Game, Dictator Game) was assessed. RESULTS Decisions in the social interaction tasks of both cocaine user groups were more self-serving compared with controls as cocaine users preferred higher monetary payoffs for themselves. In the Iowa Gambling Task, only dependent cocaine users were more likely to choose disadvantageous card decks, reflecting worse decision-making. They were also more likely to choose immediate smaller rewards over larger delayed rewards in the Delay Discounting task. CONCLUSIONS Our results imply that both recreational and dependent cocaine users are more concerned with their own monetary gain when interacting with another person. Furthermore, primarily dependent cocaine users are less foresighted and more impulsive regarding immediate reward. Overall, social interaction deficits are already present in recreational users, while non-social decision-making deficits occur predominantly in dependent cocaine users. Thus, social interaction training and cognitive remediation strategies may improve treatment success and quality of life in cocaine dependence.

Abstract
For well over a decade, researchers in Porto Alegre, Brazil, have been documenting the extent of the AIDS epidemic in the region, with a specific focus on the linkages between drug use and HIV seropositivity. Virtually all of the studies conducted during those years found injection drug use (IDU) to be the major vector for HIV seropositivity in this population. However, recent research found that the number of IDUs had declined significantly. Qualitative interviews and focus groups suggested many reasons for this decline: (1) many had died, because they had never heard of AIDS or HIV, and were unaware of how HIV is transmitted. As a result, they had become infected through the sharing of injection paraphernalia. (2) The quality of street cocaine had declined, making injection difficult. (3) Because of a fear of AIDS, some shifted to the smoking of crack, which had become a newly availability commodity in the street culture. Within this context, this article describes the qualitative data describing the decline of cocaine injecting and the corresponding emergence of crack use in Porto Alegre, Brazil, and related HIV risks.

Abstract
Description of a gas chromatograph designed for express analysis of explosives (2,4-dinitrotoluene, 2,4,6-trinitrotoluene, pentaerythritol tetranitrate), chemical warfare agents (mustard gas, lewisite, sarin) and drugs (heroin, cocaine hydrochloride, crack) is given. The devices comprises a multicapillary chromatographic column and an ion mobility increment spectrometer (MCC-IMIS). The main analytical characteristics of an IMIS (estimated detection limit (DL), linear dynamic range (LDR), speed of response) and a chromatographic column (separation power, degree of separation, a number of possible peaks at a chromatogram section, divided by analysis time) are determined. The maximum value of DL equal to 5 pg/ml was registered for cis-alpha-LW, and the lowest one of 0.001 pg/ml was for cocaine. The maximum value of LDR equal to 1000 was registered for sarin and the lowest one of 150 was for the ions of lewisite. Speed of response of one compound detection with the IMIS was 0.7 s.

Abstract
AIMS To examine whether neighborhood racial characteristics are associated with the under reporting of life time cocaine/crack use. DESIGN A household survey of high-risk communities with above-average admissions to state-supported drug and alcohol treatment programs. SETTING Chicago, Illinois, USA. PARTICIPANTS A total of 303 adults. MEASURES Self-reported use of cocaine/crack during a respondent's life time, hair test assays for cocaine use and level of neighborhood diversity measured using the Simpson Index. FINDINGS Respondents from more segregated neighborhoods were more likely than those from diverse neighborhoods to under report life time cocaine/crack use. CONCLUSIONS Neighborhood racial characteristics should be considered as an important factor in household surveys on illicit substance use.

Abstract
A continuing social problem is presented by the large number of individuals who use crack cocaine. Recent research has identified unique pyrolysis products of crack or burned cocaine as anhydroecgonine methylester (AEME) and ecgonidine (ECD) through gas chromatography/mass spectrometry (GC/MS) that allow for the detection of crack use distinct from other cocaine use. However, there have been no large-scale studies to document the presence and prevalence of these substances in sweat. A new sweat-testing appliance called a fastpatch was developed for this study. Through mild heating and a slightly larger collection pad than a standard Pharmchek( trade mark ) sweat patch, this product shows the promise of shorter required wear periods than standard sweat patches, and possibly longer time-periods of detected use. One hundred and eighty subjects wore 360 fastpatch prototypes (one per hand). However, subsequent analysis determined that only one patch per subject was needed to obtain sufficient sweat eluate for GC/MS. Cocaine use was detected in sweat of 92% of subjects through GC/MS, comparing favorably with 91% with EMIT urinalysis. Crack metabolites were detected in 54% of subjects. The predominant analyte detected was AEME. There were no significant differences in detection rates between 15-, 20- and 30-minute wear periods. All wear periods detected both cocaine use in general and crack use successfully. These results suggest that crack use as distinct from other cocaine use can be detected in sweat and that fastpatches are a promising new way to detect drugs of abuse.

Abstract
Body stuffer, sometimes called "mini packer", is the definition of someone who admits to or is strongly suspected of ingesting illegal drugs in order to escape detection by authorities, and not for recreational purposes or to transport the drug across borders. Cocaine is the drug most commonly involved in the body stuffer syndrome. Reported cases of body stuffer deaths are rare, however a fatality related to the ingestion of a plastic bag containing cocaine is described regarding a 17-year-old dealer. The authors describe how the cocaine body stuffer syndrome differs from the usual body packer. Histological and toxicological findings are examined and discussed for a better definition of this unique syndrome.

Abstract
A total of 30 human head-hair samples were analyzed for cocaine (COC), cocaethylene (CE), benzoylecgonine (BE), methylecgonine (EME), and norcocaine (NCOC) using a sensitive positive ion chemical ionization gas chromatography-tandem mass spectrometry (GC-MS-MS) method. All 30 hair samples had been previously submitted to the laboratory and had confirmed positive for cocaine. Hair samples (20 mg each) were cut into small segments (2-5 mm) and incubated overnight at 45 degrees C in 0.1 N HCl after the addition of 50 microL of an internal standard mix of COC-d3 (1.0 ng/mg), BE-d3 (0.5 ng/mg), EME-d3 (0.25 ng/mg), and NCOC-d3 (0.25 ng/mg). The samples were then extracted with Clean Screen extraction columns from United Chemical Technologies, Inc. The final extract was evaporated to dryness and derivatized with 50 microL of 1,1,1,3,3,3-hexafluoro-2-propanol and 50 microL of trifluoroacetic anhydride at 90 degrees C for 15 min. The derivatized samples were allowed to cool to room temperature, evaporated to dryness, and then reconstituted in 50 microL of ethyl acetate. Parent set masses (unbolded ions) and product ions were m/z 304 and m/z 182 and 82 (COC), m/z 307 and m/z 185 and 85 (COC-d3), m/z 318 and m/z 196 and 82 (CE), m/z 440 and m/z 318 and 105 (BE), m/z 443 and m/z 321 and 105 (BE-d3), m/z 296 and m/z 182, and 82 (EME), m/z 299 and m/z 185 and 85 (EME-d3), m/z 403 and m/z 386 and 105 (NCOC), m/z 406 and m/z 389 and 105 (NCOC-d3). Quantitation was accomplished by calculating the area ratio of the higher mass product ion (underlined ions) of analyte to the respective internal standard based on multilevel calibrations from 0.01 to 10.0 ng/mg. The GC-MS-MS method had a limit of detection of 0.01 ng/mg and a limit of quantitation of 0.05 ng/mg for all five analytes. COC, BE, and EME were detected in all 30 samples, and CE and NCOC were found in 19 and 29 samples, respectively. The average relative percentages of each metabolite normalized to the cocaine concentrations were 12.8%, 15.4%, 1.8%, and 2.5% for BE, CE, EME, and NCOC, respectively.

Abstract
The use of hair as a specimen for the determination of drug use remains controversial. Scientists disagree upon whether environmental drug contamination (e.g. smoke) can be differentiated from actual drug use. Children whose parents use drugs (particularly crack) at home are considered to be at risk. Using the hair of the children to determine exposure gives extra credibility to the child protective services and allows them to remove children from dangerous households. Children are tested when there are credible reasons for suspecting drug exposure. In Blackhawk Country, Iowa, this program was implemented in late 1994, and since then many children have tested positively for drugs, the majority of the hair containing cocaine or methamphetamine. In some cases, cocaethylene and benzoylecgonine were also found in the hair of the children. While the presence of benzoylecgonine can be explained by exposure to crack smoke, the presence of cocaethylene suggests ingestion of cocaine and alcohol. Blackhawk Country Juvenile Court have found the program to be so useful in helping children, that they have extended hair testing from Child Protective allegation investigations to ongoing court cases and even delinquency hearings.

Abstract
The use of cocaine in the United States has reached near epidemic proportions. A major factor responsible for the dramatic increase in cocaine use is the ability to freebase cocaine and extract essentially pure drug to be smoked as crack. As a result, a variety of respiratory problems temporally associated with crack inhalation have been reported. Cocaine may cause changes in the respiratory tract as a result of its pharmacologic effects exerted either locally or systemically, its method of administration (smoking, sniffing, injecting), or its alteration of central nervous system neuroregulation of pulmonary function. These changes include such diverse disorders as thermal airway injury, pulmonary edema and hemorrhage, hypersensitivity reactions, and interstitial lung disease. However, a review of the pulmonary pathology and dysfunction associated with crack and/or cocaine use indicates that the reported changes are most likely multifactorial, even idiosyncratic, and fails to reveal common features diagnostic of cocaine use. It is likely that the spectrum of cocaine-induced pulmonary disease will continue to enlarge.

Abstract
Cocaine has been shown to accumulate in hair of admitted users. Before using this test to verify cocaine use, however, it is crucial to differentiate between systemic exposure and external contamination from being in contact with crack smoke. In the present studies, the authors document that pyrolysis of crack results in hair accumulation of cocaine, but not its benzoylecgonine metabolite, whereas after admitted cocaine use both species are detectable in hair. External contamination with crack smoke is washable, whereas systemic exposure is not. The authors suggest these two criteria to distinguish systemic exposure from external contamination.
