RESUMEN
AIMS: Illegal drug markets are often assumed to be violent and predatory due to the absence of third-party enforcement. While cannabis markets are generally considered to be relatively more peaceful, there has been little investigation of the levels of conflict and victimization among small-scale cannabis growers, particularly under different cannabis policy and enforcement settings. This paper explores prevalence and predictors of conflict and social control among small-scale cannabis growers. METHODS: The data were obtained from an online convenience survey of small-scale cannabis growers from 13 countries (Austria, Canada, Denmark, Finland, France, Germany, Israel, New Zealand, Portugal, Switzerland, United Kingdom, United States, and Uruguay) from August 2020 to September 2021 (N = 5667). Key measures collected included the types of victimization due to cannabis growing, the perpetrators of these predatory actions, reasons for the conflict, and the grower's response to being victimized. Multivariate logistic regression models were used to identify predictors of different types of victimization and social control responses among cannabis cultivators. RESULTS: Most growers (76 %) never directly experienced violence or other victimization related to their cannabis cultivation. However, about one-quarter of growers had been victimized at some point, mostly involving theft, with physical violence rare. Growing outdoors, growing with others, growing more plants, and being a more seasoned grower increased the risk of victimization. Growers who were motivated by profit were more susceptible to theft. Surprisingly, growers in legal recreational jurisdictions experienced greater levels of theft and violent victimization than growers in illegal jurisdictions. Nonviolent social control responses predominated among the growers, mostly characterized by toleration but also avoidance and negotiation. CONCLUSION: While most growers reported no victimization, a substantial minority did so, largely theft rather than violence, and typically did not report employing retaliatory violence. Social control responses were mostly nonviolent. These findings varied under different cannabis policy and enforcement environments. Cannabis legalization does not eliminate opportunities for theft and violence related to cannabis cultivation.
RESUMEN
BACKGROUND: To examine the prospects for "ending the HIV epidemic" among persons who inject drugs (PWID) in Haiphong, Vietnam. Reaching an incidence of <0.5/100 person-years at risk (PY) was used as an operational definition for "ending the epidemic." METHODS: A respondent driven sampling study of 603 PWID was conducted from September to October 2014. Current heroin use (verified with urine testing and marks of injection) was an eligibility requirement. A structured questionnaire was administered by trained interviewers to obtain demographic, drug use, and risk behavior data; HIV counseling and testing and HCV testing was also conducted. Two methods (by assuming all new injectors were HIV negative at first injection and by slope of prevalence by years injecting) were used for estimating HIV among persons injecting for <5 years ("new injectors"). Comparisons were made to the HIV epidemic among PWID in New York City and modeling of the HIV epidemic in Can Tho province. RESULTS: HIV prevalence was 25% in 2014, down from 68% in 2006 and 48% in 2009; overall HCV prevalence in the study was 67%. Among HIV seropositive PWID, 33% reported receiving antiretroviral treatment. The great majority (83%) of subjects reported pharmacies as their primary source of needles and syringes and self-reported receptive and distributive syringe sharing were quite low (<6%). Estimating HIV incidence among non-MSM male new injectors with the assumption that all were HIV negative at first injection gave a rate of 1.2/100 person-years (95% CI -0.24, 3.4). Estimating HIV incidence by the slope of prevalence by years injecting gave a rate of 0.8/100 person-years at risk (95% CI -0.9, 2.5). CONCLUSIONS: The current HIV epidemic among PWID in Haiphong is in a declining phase, but estimated incidence among non-MSM new injectors is approximately 1/100 person-years and there is a substantial gap in provision of ART for HIV seropositives. Scaling up interventions, particularly HIV counseling and testing and antiretroviral treatment for all seropositive PWID, should accelerate the decline. Ending the epidemic is an attainable public health goal.
