BACKGROUNDnThis 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.nnnMETHODSnThis 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.nnnRESULTSnOverall 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.nnnCONCLUSIONSnThese 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.

BACKGROUNDnInternet-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.nnnMETHODSnDescriptive statistics showing eligibility and completion rates and recruitment source by country of residence.nnnRESULTSnOver 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.nnnCONCLUSIONnThrough 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.

BACKGROUNDnThe production and consumption of cannabis for the treatment of medical conditions is of increasing importance internationally; however, research on different aspects of the phenomenon is still scarce. In this article, we report findings from a cross-cultural study of small-scale cannabis cultivation for medical purposes. This kind of comparative study has not been done previously.nnnMETHODSnThe data were gathered with a help of web surveys conducted by the Global Cannabis Cultivation Research Consortium (GCCRC) in Australia, Belgium, Denmark, Finland, Germany and the UK (N=5313). In the analysis we compare reports of medical motives, for what conditions cannabis is used, whether users have diagnoses for these conditions and whether the use of cannabis been recommended as a treatment of those conditions by a medical doctor. Descriptive statistics are used to show the main commonalities and noteworthy disparities across different countries.nnnRESULTSnFindings from countries were quite similar, even though several national differences in details were found. Growing cannabis for medical purposes was widespread. The majority of medical growers reported cultivating cannabis for serious conditions. Most of them did have a formal diagnosis. One fifth had got a recommendation from their doctor, but in most cases cannabis use was self-medication which was not discussed with their doctors.nnnCONCLUSIONnThere is a wider demand for licit access for medical cannabis than currently available in these countries. Ideologically, medical growers can be seen distancing themselves from both the legal and illicit drug markets. From a harm reduction perspective, it is worrying that, in the context of present health and control policies in these countries, many medical growers are using cannabis to treat serious medical conditions without proper medical advice and doctors guidance.

Research on cannabis cultivation has identified several factors associated with a growers likelihood of detection by law enforcement. However, these studies are difficult to compare, as they drew from different data sources and methods, and have focused on only one geographical location. This article revisits the issue of detection using a large sample of cannabis cultivators recruited in three countries: Belgium (nu2009=u2009659), Denmark (nu2009=u2009560) and Finland (nu2009=u20091296). Respondents were recruited in the context of a self-reported online survey conducted successively in each country between 2006 and 2008. Multivariate analyses suggest several country-specific similarities and differences. Importantly, the Finnish growers reported being arrested significantly more often than Belgians or Danes. The probability that Finnish growers would be arrested increased with time spent on growing, the size of the cultivation site and when respondents did not work alone. In Denmark, the risks increased with the size of the cultivation-related network, but decreased when respondents started growing later in life. In Belgium, no cultivation-related characteristics were associated with detection. The results indicate that the risks of apprehension for cannabis cultivation are typically country-specific. These findings are discussed in the context of country-specific policies in regards to cannabis.

Abstract Aim: To compare characteristics of recreational vs. medical growers in a sample of small-scale cannabis cultivators from 12 countries. Methods: Six thousand eight hundred ninety six respondents who took part in an online survey were divided into three groups as: those who reported growing for recreational use, those cultivating for medical purposes who also reported use of other illegal drugs, and those who reported cultivation for medical use and didn’t use other illegal substances. The groups were compared using multinomial logistic regression. Findings: In comparison to recreational growers, the two groups of medical growers included more females, consumed cannabis more frequently, and were more likely to cite health-related motivations for growing. The medical growers without other illicit drug use shared some of the same features with the medical growers with illicit drug use, but in comparison to both other groups, they were older, used less alcohol and tobacco, and were less likely to be involved in illicit activities other than drug crimes. Conclusions: Findings suggest that claims of medical use are not simply an attempt to justify personal cannabis consumption, but do at least partly reflect a genuine belief in medical benefit. However, those growing cannabis for medical reasons form a heterogeneous group of people.

Green, green grass of home – Small-scale cannabis cultivation and social supply in Finland

Pekka Hakkarainen; Jussi Perälä

Three different datasets are used to study the home growing of cannabis and social supply connected to it in Finland. Data from a representative population survey (N=2,023) traces the prevalence of home growing. Data from an online questionnaire among cannabis growers (N=1,298) in spring 2009 and interviews with home growers (N=38) are used to draw a portrait of growers and to describe their thinking: What does home growing involve in practice? Who are the growers? What is the purpose of growing, and what happens to the crop?

BACKGROUNDnIt is now commonly accepted that there exists a form of drug supply, that involves the non-commercial supply of drugs to friends and acquaintances for little or no profit, which is qualitatively different from profit motivated drug dealing proper. Social supply, as it has become known, has a strong conceptual footprint in the United Kingdom, shaped by empirical research, policy discussion and its accommodation in legal frameworks. Though scholarship has emerged in a number of contexts outside the UK, the extent to which social supply has developed as an internationally recognised concept in criminal justice contexts is still unclear.nnnMETHODSnDrawing on an established international social supply research network across eleven nations, this paper provides the first assessment of social supply as an internationally relevant concept. Data derives from individual and team research stemming from Australia, Belgium, Canada, Czech Republic, Finland, Germany, Hong Kong, the Netherlands, England and Wales, and the United States, supported by expert reflection on research evidence and analysis of sentencing and media reporting in each context. In situ social supply experts addressed a common set of questions regarding the nature of social supply for their particular context including: an overview of social supply research activity, reflection on the extent that differentiation is accommodated in drug supply sentencing frameworks; evaluating the extent to which social supply is recognised in legal discourse and in sentencing practices and more broadly by e.g. criminal justice professionals in the public sphere. A thematic analysis of these scripts was undertaken and emergent themes were developed. Whilst having an absence of local research, New Zealand is also included in the analysis as there exists a genuine discursive presence of social supply in the drug control and sentencing policy contexts in that country.nnnRESULTSnFindings suggest that while social supply has been found to exist as a real and distinct behaviour, its acceptance and application in criminal justice systems ranges from explicit through to implicit. In the absence of dedicated guiding frameworks, strong use is made of discretion and mitigating circumstances in attempts to acknowledge supply differentiation. In some jurisdictions, there is no accommodation of social supply, and while aggravating factors can be applied to differentiate more serious offences, social suppliers remain subject to arbitrary deterrent sentencing apparatus.nnnCONCLUSIONnDue to the shifting sands of politics, mood, or geographical disparity, reliance on judicial discretion and the use of mitigating circumstances to implement commensurate sentences for social suppliers is no longer sufficient. Further research is required to strengthen the conceptual presence of social supply in policy and practice as a behaviour that extends beyond cannabis and is relevant to users of all drugs. Research informed guidelines and/or specific sentencing provisions for social suppliers would provide fewer possibilities for inconsistency and promote more proportionate outcomes for this fast-growing group.

Characteristics of cannabis cultivation in New Zealand and Israel

Purpose n n n n nThe purpose of this paper is to explore the characteristics of small-scale cannabis cultivation in New Zealand and Israel. n n n n nDesign/methodology/approach n n n n nAn online survey of predominantly small-scale cannabis cultivators had previously been conducted in 11 countries in 2012/2013. The same core online survey was subsequently conducted in New Zealand and Israel in 2016/2017, and comparisons made with the original 11 countries. n n n n nFindings n n n n nOnly around one third of the New Zealand and Israeli cannabis growers had sold cannabis, and the majority of these did so only to cover the costs of cultivation. The median number of cannabis plants cultivated per crop by the New Zealand and Israeli growers was five and two, respectively. The leading reasons provided for growing cannabis by both the New Zealand and Israeli growers were to provide cannabis for personal use and to share with others. A higher proportion of New Zealand than Israeli growers reported growing cannabis for medicinal reasons. A total of 16 per cent of the New Zealand and 17 per cent of Israeli growers had come into contact with the police due to their cannabis cultivation. The findings suggest small-scale cannabis cultivation in New Zealand and Israel is largely a means of “social supply” of cannabis, and this is consistent with the findings from the original 11 countries. The higher incidence of growing cannabis for medicinal purposes in New Zealand may reflect the limited official access to medical cannabis. Significant minorities of small-scale cannabis growers in both countries had contact with police, putting them at risk of the negative consequences of a criminal conviction. n n n n nOriginality/value n n n n nTo date, the research into cannabis cultivation has largely consisted of studies of individual countries. However, given the global popularity of cannabis use, and the recent spread of cannabis cultivation to countries that traditionally have not produced cannabis, via utilisation of indoor growing techniques, there is now a strong case for international comparative research. Following the success of the surveys in the original 11 countries, New Zealand and Israeli members of the Global Cannabis Cultivation Research Consortium international collaboration chose to undertake surveys in their own countries in 2016/2017.

How do People Attribute their Polydrug Use? A Mixed Methods Approach

Kati Kataja; Karoliina Karjalainen; Jenni Savonen; Pekka Hakkarainen; Sanna Kaisa Hautala

ABSTRACT In Finland, polydrug use is generally seen as stigmatized deviant behavior. By means of the mixed methods approach, this article focuses on how people explain their polydrug use and what they attribute it to. Our findings show that these explanations vary according to sociodemography. Moreover, polydrug use is not always presented as planned and goal-oriented behavior, but also something that can occur due to sudden situational factors beyond the control of the person. Our findings implicate that the judgments regarding the deviance of polydrug use are contextual and different sociodemographic groups consider whether it is deviant behavior or not differently.
