Cannabis donation as a harm reduction strategy: a case study.

BACKGROUND: The United States (US) continues to experience unprecedented rates of overdose mortality and there is increased need to identify effective harm reduction practices. Research from Canada describes cannabis donation through harm reduction agencies as an adjunctive strategy to mitigate the negative consequences of more harmful drugs. This case study describes the operational logistics, feasibility, and potential benefits of a cannabis donation program that was operated through a harm reduction program in rural Michigan. CASE PRESENTATION: We applied a community driven research approach to gather information from harm reduction program staff about the implementation and evolution of cannabis donation efforts in Michigan. We also examined 20-months (September 2021 through May 2023) of administrative data from a cannabis company to compare the sale and donation of cannabis products. Ten cannabis-experienced harm reduction clients received cannabis donations, with clinical staff determining client interest and appropriateness, and providing weekly pick-up or delivery. To expand product availability and sustainability, we examined administrative data from a commercialcannabis company that volunteered to provide donations. This administrative data suggests that while flower products constitute most of the adult and medical sales, edible, oil, and topical products predominated donations. Further, cost analysis suggests that donations represent only 1% of total gross sales and account for much less than the expected yearly donation amount. CONCLUSIONS: Research suggests there is potential to reduce alcohol and drug use related harms of more dangerous substances through substitution with cannabis. This case study is the first to document cannabis donation as a harm reduction practice in the US and suggests potential for sustainability dependent on state laws. Findings from this case study provide a starting point for inquiry into cannabis donation as a harm reduction strategy in the US; future research is needed to fully understand the individual-level outcomes, public health impacts, necessary legal regulations, and best practices for cannabis donation programs through harm reduction organizations.

Fentanyl Exposure and Detection Strategies Utilized by Clinical Trial Participants Seeking Linkage to Opioid Use Disorder Treatment at a Syringe Service Program.

INTRODUCTION: The USA continues to face a fentanyl-driven overdose epidemic. Prior research has demonstrated users of illicit opioids are concerned about fentanyl exposure and overdose, but the strategies they report using to detect fentanyl's presence lack empirical support. This study compares self-report and biologically detected fentanyl use and investigates overdose risk and risk reduction behaviors among a sample of high-risk people who use opioids. METHODS: Structured enrollment interviews conducted as part of a larger clinical trial assessed self-reported fentanyl exposure as well as strategies used to determine believed fentanyl exposure and prevent overdose among 240 participants enrolled at a Chicago, IL syringe service program. Urinalysis measured actual fentanyl exposure. RESULTS: Most participants identified as African American (66.7%) and had considerable overdose experience (76.7% lifetime and 48% in the past year). Most also tested positive for fentanyl (93.75%) despite reporting no past year use of fentanyl or fentanyl-adulterated drugs (64.17%). The most utilized approaches reported for identifying fentanyl exposure were stronger effects of the drug (60.7%), sight or taste (46.9%), and being told by someone using the same drugs (34.2%). Few participants (14%) reported using fentanyl test strips. No significant associations were identified between self-report and urinalysis measures or urinalysis results and risk reduction strategies. CONCLUSION: This study adds to prior fentanyl exposure risk research. The disconnect between participants' fentanyl detection methods and reported overdose experiences supports the need for more research to identify and understand factors driving access and use of overdose prevention resources and strategies.

Prevalence and factors associated with neck injection among people who inject drugs in San Francisco, California.

BACKGROUND: Groin and neck injections are generally a last resort for people who inject drugs (PWID) who do not have easy access to functioning veins. These alternative injection practices can lead to an increased likelihood of adverse health outcomes. There is still much we do not know about groin and neck injections among PWID in the US, as the literature to-date comes from studies primarily focused on groin injections outside the US. We assessed prevalence, predictors, and associated behaviors of neck injection through a survey fielded in San Francisco, California, US. METHODS: The sample comes from a longitudinal observational study that used targeted sampling to recruit PWID in San Francisco. The current study sample includes 239 PWID who completed their 12-month survey between June 2019 and June 2020. RESULTS: About a third of the sample reported injecting in their neck in the past 30 days, with the most common reason being lack of available veins. Age, past 6-month abscess / soft tissue infection, and past 30-day use of opioids mixed with cocaine were significantly associated with past 30-day neck injection in the final multivariate model. Past 30-day neck injection was also significantly associated with being injected by another person in the past 30 days. CONCLUSIONS: PWID at higher risk for vein deterioration were more likely to inject into their neck. Harm reduction strategies such as safer injection counseling, safe smoking supplies, use of "street doctors," and safe consumption sites may reduce instances of neck injection and/or associated health risks.

Age of onset and alcohol and cannabis use disorders among Mexican American young adults: Robust substance-specific effects of early use as a risk factor.

We investigated the substance-specific and cross-substance risk associated with early onset (before age 15) of drunkenness and cannabis use in the subsequent development of alcohol (AUD) and cannabis use disorder (CUD) in Mexican American young adults. Survival analyses employed Cox proportional hazards models for AUD and CUD, separately. In cross-risk analyses, we modeled estimates for those participants reporting lifetime use of both substances. Early onset of drunkenness and early onset of cannabis use were associated with shorter time to AUD and CUD, respectively, even after accounting for psychiatric disorders. While there were no cross-risk associations, adjusting for psychiatric disorders and early onset cannabis use attenuated the association of early drunkenness with AUD.

Consuming illicit opioids during a drug overdose epidemic: Illicit fentanyls, drug discernment, and the radical transformation of the illicit opioid market.

BACKGROUND: North America continues to face an opioid overdose epidemic, driven by persistent increases in illicit fentanyls and fluctuations in potency leading to uncertainty for consumers. This qualitative study was conducted to better understand how people who inject drugs (PWID) came to recognize fentanyl as a growing adulterant of heroin and the subsequent sensory discernment strategies they employed to continue injecting. Our main objective was to investigate how observations and knowledge are combined as homegrown techniques for detecting fentanyl and minimizing risk. Secondary objectives were to examine the impact of growing fentanyl adulteration on individual drug use behavior. METHODS: Between April and May 2019, 28 PWID (18 men, 10 women; average age = 38.43 years, SD = 9.26) were purposely recruited from a needle services program in Greensboro, North Carolina. Study participants were interviewed in-person using a qualitative, semi-structured instrument. Interviews were analyzed with a general inductive approach using NVivo12. RESULTS: Participants described methods for detecting fentanyl in illicit opioids. Sudden increases in the potency of the 'rush' and sharp decreases in the length of the 'high' were chief indicators along with changes in drug color and texture. Heavy sedation was associated with fentanyl use and histamine-releasing effects characterized as 'pins and needles' were ascribed to injecting fentanyl as a component of the rush. Fentanyl's short high helped explain higher injection frequency and heavy sedation was the leading reason for co-using fentanyl with cocaine/crack or methamphetamine. CONCLUSION: PWID have the capacity to recognize changes to the illicit opioid supply. Study participants navigated unpredictable fluctuations in the illicit opioid market by employing homegrown discernment techniques, modifying drug use behavior, and co-using non-opioid drugs. Researchers and policymakers should involve PWID as subject matter experts to help modernize harm reduction for the fentanyl age with practical strategies to boost resiliency and save lives.

Consumer discernment of fentanyl in illicit opioids confirmed by fentanyl test strips: Lessons from a syringe services program in North Carolina.

BACKGROUND: The United States (U.S.) continues to witness an unprecedented increase in opioid overdose deaths driven by precipitous growth in the supply and use of illicitly-manufactured fentanyls (IMF). Fentanyl's growing market share of the illicit opioid supply in the U.S. has led to seismic shifts in the composition of the country's heroin supply. The growth in fentanyl supply has transformed illicit opioid markets once offering heroin with fairly consistent purity and potency to a supply overpopulated with fentanyl(s) of inconsistent and unpredictable potency. In response, people who inject drugs (PWID) have developed a number of sensory strategies to detect fentanyl in illicit opioids. The current study examined the accuracy of sensory discernment strategies by measuring study participants' descriptions of the last opioid injected and checked with a fentanyl test strip (FTS) by that test's positive/negative result. The primary objective was to determine associations between FTS results and descriptions of the illicit opioid's physical appearance and physiological effects. METHODS: Between September-October 2017, a total of 129 PWID were recruited from a syringe services program in Greensboro, North Carolina and completed an online survey about their most recent use of FTS. Participants were instructed to describe the appearance and effects associated with the most recent opioid they injected and tested with FTS. We conducted bivariate and multivariate analyses to determine differences in positive vs negative FTS results and the physical characteristics and physiological experiences reported. An exploratory analysis was also conducted to describe the types and bodily locations of unusual sensations experienced by PWID reporting positive FTS results. RESULTS: For physical characteristics, 32% reported that the drug was white before adding water and 38% reported the solution was clear after adding water. For physiological effects compared to heroin, 42% reported a stronger rush, 30% a shorter high, 30% a shorter time to the onset of withdrawal symptoms, and 42% experienced unusual sensations. In the multivariable model adjusting for demographics and polydrug correlates, white color of drug before adding water, stronger rush, shorter time to withdrawal, and unusual sensations were significantly associated with a positive FTS result. The most common unusual sensations were pins and needles (51%), warming of the head and face (35%), and lightheadedness (30%), and the most common locations where sensations occurred were face and neck (61%), arms/legs (54%), and chest (37%). CONCLUSION: We found positive FTS results were significantly associated with the physical characteristics and physiological effects described by PWID. Descriptions concerning physical appearance were consistent with law enforcement profiles of illicitly-manufactured fentanyl and physiological effects were concomitant with scientific and clinical medical literature on iatrogenic fentanyl use. Taken together, these findings suggest sensory strategies for detecting fentanyl in illicit opioids may be an effective risk reduction tool to help consumers navigate unpredictable markets more safely.

Comparing medical and recreational cannabis use among employees: associations with health and work-related outcomes.

Nearly one in five US employees reports having used cannabis in the past year. As policies and laws regarding cannabis use rapidly change, concerns have arisen over employees' use of cannabis, for both medical and recreational purposes. While extant workplace research has not distinguished between types of cannabis users, other studies have found that medical users are clinically and socio-demographically different from non-medical users. This study utilized a sample of employed National Survey on Drug Use and Health (NSDUH) respondents to examine differences in workplace characteristics and health outcomes among employed medical, recreational, and mixed-use cannabis users. While some differences were initially seen when examining health and work-related outcomes between the groups, several changed after controlling for other important health-related factors. One key difference between the user groups is the higher percentages of medical and mixed-use cannabis users in the construction and mining industries. This study discusses future research needs, as well as practical implications for workers and employers.
