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.

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.

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.
