Not all screens are created equal: examination of surface features and other physical properties of commonly used screen materials for smoking drugs.

BACKGROUND: Brass screens are considered an essential part of the safer drug smoking/inhalation supplies and are widely distributed by harm reduction programs in Canada. However, the use of commercially available steel wools as screens for smoking crack cocaine remains a common practice among people who smoke drugs in Canada. Use of these steel wool materials is associated with different adverse effects on health. This study aims to determine what changes folding and heating have on several filter materials, including brass screens and commercially available steel wool products, and examine the implications of these changes on health of people who smoke drugs. METHODS: This study investigated the microscopic differences, studied by optical and scanning electron microscopy, between four screen and four steel wool filter materials used in a simulated drug consumption process. New materials were manipulated, compacted into its own Pyrex® straight stem using a push stick and then heated with a butane lighter simulating a common method in preparing drugs for consumption. The materials were studied in the as-received (new), as-pressed (compressed and inserted into the stem tube but without heating) and as-heated (compressed and inserted into the stem tube and heated with a butane lighter) conditions. RESULTS: The steel wool materials with the smallest wire thicknesses were found to be the easiest to prepare for pipe use, but degrade significantly during shaping and heating, making them wholly unsuitable as a safe filter material. In contrast the brass and stainless steel screen materials remain mostly unchanged by the simulated drug consumption process. After the stainless steel pellet screen, the Brass Impact 2.0 screen material had the best characteristics of the materials tested due to its mesh wire diameter, pitch, alloy choice and its pre-strained state. CONCLUSION: Commonly used steel wool alternatives degrade during the handling and stem insertion, and heating the screens in the stem. Debris is generated by wool deformation on insertion and after heating that easily separates from the screen and can be inhaled during drug consumption. The brass and stainless steel screen materials are safer to use as they remain mostly stable during the simulated drug consumption process.

Smoke Gets in the Eye: A systematic review of case reports of ocular complications of crack cocaine use.

ISSUES: Use of crack cocaine and associated medical complications persists globally. Some reports in medical literature describe a sight-threatening condition commonly referred to as 'crack eye' or 'crack eye syndrome'. The purpose of this review is to describe what is known about crack eye from case reports in peer-reviewed literature. APPROACH: A structured search was completed in MEDLINE, TOXLINE, EMBASE, PsychInfo, Scopus and Biomed Central, to collect case reports and case series on corneal complications attributed to crack cocaine smoking. KEY FINDINGS: Of 111 articles screened, 11 contained case reports or series. Thirty individual cases of 'crack eye' were reported. The majority (63%) of cases had bilateral involvement; 83% of all cases with microbial culture results had corneal infections. Aggressive treatment caused an improvement in 95% of all cases and 23% of all cases were lost to follow up. Of those who received treatment for corneal complications associated with crack cocaine, 22% remained with significant visual impairment (hand motions only) in the affected eye. IMPLICATIONS: Clinicians should consider crack cocaine involvement in patients presenting with corneal disease without known predisposing factors, and elicit comprehensive drug histories to prevent a reduction in visual acuity. CONCLUSION: Corneal complications of crack cocaine smoking are caused by a number of synergistic factors, including direct toxicity of crack cocaine vapours to surface cells, impairment of neurogenic support to corneal epithelial integrity, desiccation of the eye surface due to diminished blinking reflex, low level chemical burns and mechanical denudement of surface cells through eye rubbing.

'It's our safe sanctuary': Experiences of using an unsanctioned overdose prevention site in Toronto, Ontario.

BACKGROUND: Overdose prevention sites (OPSs) are spaces where people can consume drugs under the supervision of trained volunteers or staff and receive help in the event of an overdose. Unsanctioned OPSs are a grassroots response to the current opioid crisis in Canada. METHODS: We used rapid evaluation methods to study the experiences of 30 individuals accessing the smoking and injection services at the first unsanctioned OPS in Toronto, Ontario using semi-structured interviews. Data were analyzed using an applied thematic analysis approach to identify emergent themes related to service user experiences, characteristics of the risk environment, and recommended changes to the service model. RESULTS: The OPS represented a safe sanctuary and brought a sense of belonging to a community that often experiences discrimination. Valued aspects included: shelter; protection from violence; safety from overdoses; free equipment; information about health and social services; food and beverages; and socializing and connecting with others. Integrating peer workers in the design and delivery of services encouraged service users to visit the site. The OPS changed the risk environment by: providing access to the first supervised smoking service in Toronto; having few explicit rules and a communal approach to making new rules; allowing assisted injection, and negotiating with police to allow people to access the site with minimal contact. Service users noted the need to ensure a safe space for women and recommended extended hours of operation and moving to a more permanent space with heat and lighting for both smoking and injecting drugs. CONCLUSION: The unsanctioned OPS in Toronto served an important role in defining new, community-led, flexible responses to opioid overdose-related deaths at a time of markedly increasing mortality. Providing harm reduction services in diverse settings and expanding services to include smoking and assisted injection may increase access for marginalized people who use drugs.

Distribution of Harm Reduction Kits in a Specialty HIV Hospital.

Casey House, a small Toronto, Ontario, hospital for people living with HIV, implemented a harm-reduction kit distribution program in October 2014 to decrease harms from reuse of injection and smoking equipment among its clients-inpatients and outpatients. Program statistics (November 2014-June 2017) show an increase in the number of kits-injection and smoking-distributed each year. The program is perceived by staff to communicate openness and increased willingness of clinicians and clients to discuss drug-related harms.

Scoping out the literature on mobile needle and syringe programs-review of service delivery and client characteristics, operation, utilization, referrals, and impact.

BACKGROUND: Needle and syringe program (NSP) service delivery models encompass fixed sites, mobile services, vending machines, pharmacies, peer NSPs, street outreach, and inter-organizational agreements to add NSP services to other programs. For programs seeking to implement or improve mobile services, access to a synthesis of the evidence related to mobile services is beneficial, but lacking. METHODS: We used a scoping study method to search MEDLINE, PSYCHInfo, Embase, Scopus, and Sociological for relevant literature. We identified 39 relevant manuscripts published between 1975 and November 2017 after removing duplicates and non-relevant manuscripts from the 1313 identified by the search. RESULTS: Charting of the data showed that these publications reported findings related to the service delivery model characteristics, client characteristics, service utilization, specialized interventions offered on mobile NSPs, linking clients to other services, and impact on injection risk behaviors. Mobile NSPs are implemented in high-, medium-, and low-income countries; provide equipment distribution and many other harm reduction services; face limitations to service complement, confidentiality, and duration of interactions imposed by physical space; adapt to changes in locations and types of drug use; attract people who engage in high-risk/intensity injection behavior and who are often not reached by other service models; and may lead to reduced injection-related risks. DISCUSSION: It is not clear from the literature reviewed, what are, or if there are, a "core and essential" complement of services that mobile NSPs should offer. Decisions about service complement for mobile NSPs need to be made in relation to the context and also other available services. Reports of client visits to mobile NSP provide a picture of the volume and frequency of utilization but are difficult to compare given varied measures and reference periods. CONCLUSION: Mobile NSPs have an important role to play in improving HIV and HCV prevention efforts across the world. However, more work is needed to create clearer assessment metrics and to improve access to NSP services across the world.

Zoning out methadone and rising opioid-related deaths in Ontario: Reforms and municipal government actions.

In this commentary, we argue that the use of amendments to bylaws by Ontario cities and municipalities to restrict where and how methadone maintenance treatment (MMT) clinics and pharmacies operate may run counter to efforts to prevent record high rates of opioid-related overdoses. As the province of Ontario seeks to reform the opioid treatment system, it is crucial to understand the structural (e.g., stigma) and treatment system organization factors that drive the actions of municipalities such as those described above. Changes that exacerbate these factors may lead to increased use of bylaws to curtail access at a time when efforts are underway to reduce alarming rates of opioid-related overdose.
