How many people in Canada use prescription opioids non-medically in general and street drug using populations?
Medical prescriptions for opioids as well as their non-medical use have increased in Canada in recent years. This study aimed to estimate the number of non-medical prescription opioid (PO) users in the general and street drug using populations in Canada. ⋯ There is an urgent need to further assess the extent and patterns of non-medical prescription opioid use, related problems and drug distribution channels in Canada.

Cannabis is the most commonly used illicit drug in Canada, used by 1 in 7 adults and 1 in 4 students. Other forms of drug use (e.g., alcohol or injection drug use) are increasingly approached within a public health policy framework that focuses on reducing harms rather than use per se. Cannabis, by contrast, remains formally controlled by a criminal justice approach that focuses on enforcing abstinence. ⋯ In a public health framework, cannabis use - especially in young populations - should be systematically monitored and high-risk patterns of use screened for in appropriate settings, e.g., schools and GP offices. Evidence-based primary and secondary prevention, treatment and enforcement need to be targeted at these high-risk patterns of use. Given the large cannabis user population, especially among young people, and the failure of the criminalization approach to discourage use, a public health framework for cannabis use is urgently needed in Canada.

To examine the relationship between density of fast food restaurants and measures of social and material deprivation at the community level in Nova Scotia, Canada. ⋯ Community-level deprivation in Nova Scotia is associated with fast food outlet density and lends support for environmental explanations for variations in the prevalence of obesity. Such findings are valuable to population health intervention initiatives targeting the modification of environmental determinants of obesity.

[The place of syringe exchange programs in reducing harm in Canadian prisoners].
The prevalence rates of illicit drug consumption within the prison system are much higher than those in the Canadian population in general. Of the substances used in detention, those of most concern to prison and public health authorities are injection drugs, as the sharing of injection drug equipment may be responsible for the high prevalence of blood-borne diseases in prison facilities. ⋯ However, despite their use in the community, needle-exchange programs are not yet allowed in penitentiaries. This article analyzes the limits of harm reduction strategies approved by the prison authorities and discusses the sources of resistance that continue to impede the realization of a pilot project to assess the feasibility of needle-exchange programs in detention in Canada.

ReviewApplying the lessons of SARS to pandemic influenza: an evidence-based approach to mitigating the stress experienced by healthcare workers.
We describe an evidence-based approach to enhancing the resilience of healthcare workers in preparation for an influenza pandemic, based on evidence about the stress associated with working in healthcare during the SARS outbreak. SARS was associated with significant long-term stress in healthcare workers, but not with increased mental illness. Reducing pandemic-related stress may best be accomplished through interventions designed to enhance resilience in psychologically healthy people. ⋯ Evidence supports the goal of developing and maintaining an organizational culture of resilience in order to reduce the expected stress of an influenza pandemic on healthcare workers. This recommendation goes well beyond the provision of adequate training and counseling. Although the severity of a pandemic is unpredictable, this effort is not likely to be wasted because it will also support the health of both patients and staff in normal times.
