Sociometric network analysis in illicit drugs research: A scoping review.

BACKGROUND: Sociometric or whole network analysis, a method used to analyze relational patterns among social actors, emphasizes the role of social structure in shaping behaviour. Such method has been applied to many aspects of illicit drug research, including in the areas of public health, epidemiology, and criminology. Previous reviews about social networks and drugs have lacked a focus on the use of sociometric network analysis for illicit drugs research across disciplines. The current scoping review aimed to provide an overview of the sociometric network analysis methods used in illicit drugs research and to assess how such methods could be used for future research. METHODS: A systematic search of six databases (Web of Science, ProQuest Sociology Collection, Political Science Complete, PubMed, Criminal Justice Abstracts, and PsycINFO) returned 72 relevant studies that met the inclusion criteria. To be included, studies had to mention illicit drugs and use whole social network analysis as one of their methods. Studies were summarized quantitatively and qualitatively using a data-charting form and a description of the studies' main topics. RESULTS: Sociometric network analysis in illicit drugs research has grown in popularity in the last decade, using mostly descriptive network metrics, such as degree centrality (72.2%) and density (44.4%). Studies were found to belong to three study domains. The first, drug crimes investigated network resilience and collaboration patterns in drug trafficking networks. The second domain, public health, focused on the social networks and social support of people who use drugs. Finally, the third domain focused on the collaboration networks of policy, law enforcement, and service providers. CONCLUSION: Future illicit drugs research using whole network SNA should include more diverse data sources and samples, incorporate mixed and qualitative methods, and apply social network analysis to study drug policy.

Where "Old Heads" Prevail: Inmate Hierarchy in a Men's Prison Unit.

Research of inmate social order is a once-vibrant area that receded just as American incarceration rates climbed and the country's carceral contexts dramatically changed. This study reengages inmate society with an abductive mixed methods investigation of informal status within a contemporary men's prison unit. The authors collect narrative and social network data from 133 male inmates housed in a unit of a Pennsylvania medium-security prison. Analyses of inmate narratives suggest that unit "old heads" provide collective goods in the form of mentoring and role modeling that foster a positive and stable peer environment. This hypothesis is then tested with Exponential Random Graph Models (ERGMs) of peer nomination data. The ERGM results complement the qualitative analysis and suggest that older inmates and those who have been on the unit longer are perceived by their peers as powerful and influential. Both analytical strategies point to the maturity of aging and the acquisition of local knowledge as important for attaining informal status in the unit. In sum, this mixed methods case study extends theoretical insights of classic prison ethnographies, adds quantifiable results capable of future replication, and points to a growing population of older inmates as important for contemporary prison social organization.

Lessons from conducting trans-national Internet-mediated participatory research with hidden populations of cannabis cultivators.

BACKGROUND: Internet-mediated research methods are increasingly used to access hidden populations. The International Cannabis Cultivation Questionnaire (ICCQ) is an online survey designed to facilitate international comparisons into the relatively under-researched but increasingly significant phenomenon of domestic cannabis cultivation. The Global Cannabis Cultivation Research Consortium has used the ICCQ to survey over 6000 cannabis cultivators across 11 countries. In this paper, we describe and reflect upon our methodological approach, focusing on the digital and traditional recruitment methods used to access this hidden population and the challenges of working across multiple countries, cultures and languages. METHODS: Descriptive statistics showing eligibility and completion rates and recruitment source by country of residence. RESULTS: Over three quarters of eligible respondents who were presented with the survey were included in the final sample of n=6528. English-speaking countries expended more effort to recruit participants than non-English-speaking countries. The most effective recruitment modes were cannabis websites/groups (33%), Facebook (14%) and news articles (11%). While respondents recruited through news articles were older, growing practice variables were strikingly similar between these main recruitment modes. CONCLUSION: Through this process, we learnt that there are trade-offs between hosting multiple surveys in each country vs. using one integrated database. We also found that although perceived anonymity is routinely assumed to be a benefit of using digital research methodologies, there are significant limits to research participant anonymity in the current era of mass digital surveillance, especially when the target group is particularly concerned about evading law enforcement. Finally, we list a number of specific recommendations for future researchers utilising Internet-mediated approaches to researching hidden populations.

Global patterns of domestic cannabis cultivation: sample characteristics and patterns of growing across eleven countries.

BACKGROUND: This article aims to provide an overview of: demographic characteristics; experiences with growing cannabis; methods and scale of growing operations; reasons for growing; personal use of cannabis and other drugs; participation in cannabis and other drug markets; contacts with the criminal justice system for respondents to an online survey about cannabis cultivation drawn from eleven countries (N=6530). Important similarities and differences between the national samples recruited will be discussed. METHODS: This paper utilizes data from the online web survey of predominantly 'small-scale' cannabis cultivators in eleven countries conducted by the Global Cannabis Cultivation Research Consortium (GCCRC). Here we focus primarily on descriptive statistics to highlight key similarities and differences across the different national samples. RESULTS: Overall there was a great deal of similarity across countries in terms of: demographic characteristics; experiences with growing cannabis; methods and scale of growing operations; reasons for growing; use of cannabis and other drugs; participation in cannabis and other drug markets, and; contacts with the criminal justice system. In particular, we can recognise that a clear majority of those small-scale cannabis cultivators who responded to our survey are primarily motivated for reasons other than making money from cannabis supply and have minimal involvement in drug dealing or other criminal activities. CONCLUSIONS: These growers generally come from 'normal' rather than 'deviant' backgrounds. Some differences do exist between the samples drawn from different countries suggesting that local factors (political, geographical, cultural, etc.) may have some influence on how small-scale cultivators operate, although differences in recruitment strategies in different countries may also account for some differences observed.

Production, perceptions, and punishment: restrictive deterrence in the context of cannabis cultivation.

BACKGROUND: American authorities have invested extraordinary resources to keep up with the growth in cannabis cultivation, and state-level cannabis laws have been changing rapidly. Despite these changes, little research on the relationship between criminal justice sanctions and grower behaviours exist, in particular research that examines restrictive deterrence - the altering of an illegal behaviour as opposed to desisting from it completely. METHODS: We examine restrictive deterrence in the context of cannabis cultivation by modelling the relationship between the threat of sanctions and the size of cultivation site and number of co-offenders. We use data from an anonymous web survey where participants were recruited through advertisements on websites related to cannabis use and cultivation. Negative binomial regression were used on 337 cases that contain valid data on size of cultivation site and 338 cases that contain valid data on the number of co-offenders. RESULTS: Our study found some evidence that the severity of state sanctions reduces the size of cultivation sites among growers who reside in the state. However, the number of contacts with the police had the opposite effect. In addition, we did not find a restrictive deterrent effect for the number of co-offenders, suggesting that different factors affect different decision points. Interestingly, objective skill and subjective skill had positive and independent effects on size of site. CONCLUSIONS: Results suggest that state-level sanctions have a structuring effect by restricting the size of cultivation sites but further increases in sanctions or enforcement are unlikely to deter more individuals from growing cannabis. In fact, there may be some potential dangers of increased enforcement on cannabis growers.

The global diversion of pharmaceutical drugsnon-medical use and diversion of psychotropic prescription drugs in North America: a review of sourcing routes and control measures.

AIMS: North America features some of the world's highest consumption levels for controlled psychoactive prescription drugs (PPDs; e.g. prescription opioids, benzodiazepines, stimulants), with non-medical use and related harms (e.g. morbidity, mortality) rising in key populations in recent years. While the determinants, characteristics and impacts of these 'use' problems are increasingly well documented, little is known about the 'supply' side of non-medical PPD use, much of which is facilitated by 'diversion' as a key sourcing route. This paper provides a select review of the phenomenon of PPD diversion in North America, also considering interventions and policy implications. METHODS: A conceptual and empirical review of select-peer- and non-peer-reviewed research literature from 1991 to 2010 focusing upon PPD diversion in North America was conducted. RESULT: The phenomenon of PPD diversion is heterogeneous. Especially among general populations, a large proportion of PPDs for non-medical use are obtained from friends or family members. Other PPD diversion routes involve 'double doctoring' or 'prescription shopping'; street drug markets; drug thefts, prescription forgeries or fraud; as well as PPD purchases from the internet. CONCLUSIONS: The distinct nature and heterogeneity make PPD diversion a complex and difficult target for interventions. Prescription monitoring programs (PMPs) appear to reduce overall PPD use, yet their impact on reducing diversion or non-medical use is not clear. Law enforcement is unlikely to reach PPD diversion effectively. Effective reduction will probably require reductions in overall PPD consumption volumes, although such will need to be accomplished without compromising standards of good medical (e.g. pain) care.

Convenient labour: the prevalence and nature of youth involvement in the cannabis cultivation industry.

BACKGROUND: The emergence of cannabis cultivation in industrialised countries may offer adolescents, especially those living in regions suitable for outdoor cultivation, new opportunities to participate in the drug trade. The current study examines the prevalence and the nature of youth involvement in cannabis cultivation in an important agricultural region of Quebec, Canada. METHODS: A self-report delinquency survey was administered to 1262 adolescents between 13 and 17 years who were attending one of four secondary schools in that region. The study location was not chosen arbitrarily. The region was known for having a larger than average outdoor cannabis industry, and various media reports suggested that a substantial number of students missed school days during the cannabis harvest season, in October. RESULTS: A first set of findings show that 12% of respondents reported having participated in the cannabis cultivation industry in the past year. Such a prevalence rate is higher than for any other type of crime found in the survey (except for the general category of mischief)--including assault and theft, and is comparable to the prevalence rates found for drug dealing. Such a high prevalence rate comes in part out of need for labour in this low population density region: 35% of respondents who reported having participated in the industry in the past year, were "labourers", while many others only participated in small sites, destined for personal use. Another set of findings suggest that growers are a very diverse group: although cultivation is the most prevalent money-generating crime for gang members in the region, girls and otherwise conventional adolescents are also involved in high numbers. CONCLUSION: These results emphasise the need to design policies that concern not just the prevention of drug use among youth, but also youth involvement in the supply of drugs. In addition, it underlines the difficulty of planning general interventions in what appears to be a very heterogeneous population of growers.
