Cannabis use, use frequency, and use disorder in large metropolitan, small metropolitan, and nonmetropolitan areas.

BACKGROUND: Despite significant geographical heterogeneity of sociodemographic and clinical characteristics, little is known about potential differences in cannabis use behaviors in U.S. geographic areas. In this study, we examined cannabis use behaviors in large metropolitan, small metropolitan, and nonmetropolitan areas. We focused on interactions between geographic areas and health insurance status and medical cannabis laws (MCL). METHODS: Data came from the 2015-2018 National Survey on Drug Use and Health (NSDUH; N = 171,766 adults; N = 36,175 cannabis users). Weighted chi-squares tests of independence and multivariable Poisson regression models were used to examine study questions. RESULTS: Past-year use was highest in large metropolitan areas (16.08 %). Frequent use was highest among nonmetropolitan area users (48.67 %). Uninsured adults had a higher likelihood of past-year use (RRR = 1.21, 95 % CI = 1.14, 1.29) and frequent use (RRR = 1.27, 95 % CI = 1.14, 1.41), but a lower likelihood of cannabis use disorder (RRR = 0.77, 95 % CI = 0.66, 0.89). Uninsured adults in nonmetropolitan areas had a higher likelihood (RRR = 1.62, 95 % CI = 1.39, 1.88) of past-year use than insured nonmetropolitan area adults. MCL state residency was associated with a higher likelihood of frequent use among nonmetropolitan (RRR = 1.39, 95 % CI = 1.11, 1.74) and small metropolitan users (RRR = 1.30, 95 % CI = 1.15, 1.47). Cannabis use disorder likelihood did not vary by geographic area. CONCLUSIONS: Lack of health insurance and MCL state residency are significant variables affecting cannabis use behaviors in small metropolitan and/or nonmetropolitan areas.

Initial development of a brief assessment of cocaine demand.

Cocaine demand is a behavioral economic measure assessing drug reward value and motivation to use drug. The purpose of the current study was to develop a brief assessment of cocaine demand (BACD). Results from the BACD were compared with self-report measures of cocaine use. Participants consisted of treatment-seeking individuals with cocaine use disorder (N = 22). Results revealed that indices of brief demand were significantly associated with various self-report measures of cocaine use. Overall, these results support the utility of a BACD for assessing cocaine demand.

Association of Electronic Prescribing of Controlled Substances With Opioid Prescribing Rates.

Importance: The majority of US states have passed mandates requiring the use of electronic prescribing of controlled substances (EPCS) as a tool to reduce rates of opioid prescribing. It is not known whether increasing use of EPCS will have the intended effect. Objective: To assess the association between use of EPCS and trends in opioid prescribing. Design, Setting, and Participants: In this retrospective, longitudinal cohort study of all patients and prescribers in the 50 US states and the District of Columbia from 2010 to 2018, changes in state-level use of EPCS and concurrent changes in opioid prescribing in each state are described. Then the association between changes in the use of EPCS and opioid prescribing are estimated using state and year fixed-effects models that include covariates for policy change and state demographic change. Data Analysis was performed on May 5, 2020. Main Outcomes and Measures: The proportion of controlled substances in each state prescribed using EPCS based on opioid prescriptions per 100 persons and morphine milligram equivalents (MME) of opioids. Results: In 2018, the population-weighted percent of opioids prescribed using EPCS was 27%, up from 0% as of 2013. National rates of opioid prescriptions decreased from 78 prescriptions per 100 persons in 2013 to 53 in 2018. Over the same period, there was a decrease from 64 071 MME per 100 persons in 2013 to 40 906 MME per 100 persons in 2018, representing 36% of the 2013 level. By 2018, EPCS increased to 69.4% in states with mandates for its use and 23.6% in states without mandates. In multivariable models, a 10 percentage-point increase in the use of EPCS was associated with an additional 2 prescriptions per 100 persons (95% CI, 1.3-2.8) and a 0.8% (95% CI, 0.06%-1.5%) increase in MME per 100 persons. Conclusions and Relevance: These data suggest that an increased use of EPCS was not associated with decreased opioid prescribing or a decrease in the amount prescribed and may have been associated with a small increase in opioid prescribing. Opioid prescribing is associated with a variety of social and public health factors, and thus, despite the appeal, EPCS adoption alone may be insufficient to reduce opioid prescribing. Policy makers should consider levers to ensure that EPCS is integrated with outside data and that information is actively used to inform prescribing decisions.

Are risk minimization measures for approved drugs in Europe effective? A systematic review.

Objectives: The effectiveness of risk minimization measures (RMMs) requires evaluation. This study aims to evaluate the results of cross-sectional surveys assessing the effectiveness of RMMs in Europe (EU RM Surveys) and review the regulatory consequences. Methods: The authors searched for study reports and manuscripts of completed EU RM surveys in the EU PAS Register, MEDLINE, and Google between 01/2011 and 01/2018. Regulatory responses were extracted from Assessment Reports. Random effects models to combine proportions were used. Results: Twenty-four EU RM surveys were identified. Twenty-three studies targeted health-care professionals (HCPs). The pre-specified sample size was reached in 52% of studies. HCP participation was 5% defined as completers/invited and 89% for completers/eligible. Receipt of materials was recalled by 60% of HCPs and 77% of items scored knowledge >60%. Eight studies targeted patients/caregivers. The pre-specified sample size was reached in only two. Participation was 93%, defined as completers/eligible. Materials were received by 50-80% of patients and read by over 90%. Patients only scored knowledge >60% in 38% of items. Further action was requested by regulators in 59% of studies. Conclusion: Surveys are necessary to evaluate many RMMs. Challenges remain in the design, conduct, and reporting of these studies which may benefit from the use of standard definitions and further guidance on reporting.

Trajectories of dispensed prescription opioids among beneficiaries enrolled in a Medicaid controlled substance "lock-in" program.

PURPOSE: "Lock-in" programs (LIPs) are used by health insurers to address potential substance (eg, opioid) misuse among beneficiaries. We sought to (1) examine heterogeneity in trajectories of dispensed opioids (in average daily morphine milligram equivalents (MMEs)) over time: prior to, during, and following release from a LIP, and (2) assess associations between trajectory patterns and beneficiary characteristics. METHODS: Medicaid claims were linked to Prescription Drug Monitoring Program records for a cohort of beneficiaries enrolled in the North Carolina Medicaid LIP (n = 2701). Using latent class growth analyses, we estimated trajectories of average daily MMEs of opioids dispensed to beneficiaries across specific time periods of interest. RESULTS: Five trajectory patterns appeared to sufficiently describe underlying heterogeneity. Starting values and slopes varied across the 5 trajectory groups, which followed these overall patterns: (1) start at a high level of MMEs, end at a high level of MMEs (13.1% of cohort); (2) start medium, end medium (13.2%); (3) start medium, end low (21.5%); (4) start low, end medium (22.6%); and (5) start low, end low (29.6%). We observed strong associations between patterns and beneficiaries' demographics, substance use-related characteristics, comorbid conditions, and healthcare utilization. CONCLUSIONS: In its current form, the Medicaid LIP appeared to have limited impact on beneficiaries' opioid trajectories. However, strong associations between trajectory patterns and beneficiary characteristics provide insight into potential LIP design modifications that might improve program impact (eg, LIP integration of substance use disorder assessment and referral to treatment, assessment and support for alternate pain therapies).

Access to Strong Opioid Analgesics in the Context of Legal and Regulatory Barriers in Eleven Central and Eastern European Countries.

BACKGROUND: In 2011-2013, >95% of the global opioid analgesics consumption occurred in three regions, accounting for 15% of the world population. Despite abundant literature on barriers to access, little is known on the correlation between actual access to opioid analgesics and barriers to access, including legal and regulatory barriers. OBJECTIVE: This study aimed to evaluate the correlation between access to strong opioid analgesics and barriers to access in national legislation and regulations in 11 central and eastern European countries that participated in the Access to Opioid Medication in Europe (ATOME) project. DESIGN: Two variables were contrasted to assess their correlation: the country level of access to strong opioid analgesics indicated by the Adequacy of Consumption Measure (ACM) and the number of potential legal and regulatory barriers identified by an external review of legislation and regulations. MEASUREMENTS: A linear correlation was evaluated using a squared linear correlation coefficient. RESULTS: Evaluation of the correlation between the ACM and the number of potential barriers produces an R2 value of 0.023 and a correlation plot trend line gradient of -0.075, indicating no correlation between access to strong opioid analgesics and the number of potential barriers in national legislation and regulations in the countries studied. CONCLUSIONS: No correlation was found, which indicates that other factors besides potential legal and regulatory barriers play a critical role in withholding prescribers and patients essential pain medication in the studied countries. More research is needed toward better understanding of the complex interplay of factors that determine access to strong opioid analgesics.

"It Ruined My Life": The effects of the War on Drugs on people who inject drugs (PWID) in rural Puerto Rico.

BACKGROUND: The War on Drugs has raised the incarceration rates of racial minorities for non-violent drug-related crimes, profoundly stigmatized drug users, and redirected resources from drug prevention and treatment to militarizing federal and local law enforcement. Yet, while some states consider shifting their punitive approach to drug use, to one based on drug treatment and rehabilitation, nothing suggests that these policy shifts are being replicated in Puerto Rico. METHODS: This paper utilizes data from 360 PWID residing in four rural towns in the mountainous area of central Puerto Rico. We initially recruited 315 PWID using respondent-driven sampling (RDS) and collected data about risk practices and conducted HIV and HCV testing. During a second phase, we conducted 34 micro-ethnographic assays, in which we randomly recruited 34 participants from the first phase and included their ego networks in this phase. Our ethnographic inquiry produced significant data regarding the effects of the war on drugs on the local drug trade, drug availability, and injectors' social networks. RESULTS: Findings suggest that repressive policing has been ineffective in preventing drug distribution and use among those in our study. This type of law enforcement approach has resulted in the disproportionate incarceration of poor drug users in rural Puerto Rico, and mainly for nonviolent drug-related crimes. In addition, incarceration exposes PWID to a form of a cruel and unusual punishment: having to quit heroin "cold turkey" while the prison environment also represents a HIV/HCV risk. In turn, the war on drugs not only diverts resources from treatment but also shapes treatment ideologies, punishing non-compliant patients. CONCLUSION: Shifting the emphasis from repression to treatment and rehabilitation is likely to have a positive impact on the health and overall quality of life of PWID and their communities.

Statistical Considerations Concerning Dissimilar Regulatory Requirements for Dissolution Similarity Assessment. The Example of Immediate-Release Dosage Forms.

When performing in vitro dissolution testing, especially in the area of biowaivers, it is necessary to follow regulatory guidelines to minimize the risk of an unsafe or ineffective product being approved. The present study examines model-independent and model-dependent methods of comparing dissolution profiles based on various compared and contrasted international guidelines. Dissolution profiles for immediate release solid oral dosage forms were generated. The test material comprised tablets containing several substances, with at least 85% of the labeled amount dissolved within 15 min, 20-30 min, or 45 min. Dissolution profile similarity can vary with regard to the following criteria: time point selection (including the last time point), coefficient of variation, and statistical method selection. Variation between regulatory guidance and statistical methods can raise methodological questions and result potentially in a different outcome when reporting dissolution profile testing. The harmonization of existing guidelines would address existing problems concerning the interpretation of regulatory recommendations and research findings.

[The Reverse Traffic of Drugs Phenomenon: experience in Galicia, Spain]. / El tráfico inverso de medicamentos: experiencia en Galicia.

IInter-state movement of drugs between EU countries by pharmaceutical companies and distribution warehouses is a permitted activity called parallel trade. As Spain is among the states with lower price of these products, its main activity is shipping to other countries; however, a phenomenon has emerged in acquiring drugs for this purpose, called "reverse traffic" that develops without observing the health regulations in the legal distribution channel in our country; in which, the pharmaceutical distribution warehouses, rather than getting drugs from other pharmaceutical companies or pharmaceutical distribution warehouses under the current legislation, obtain them from community pharmacies, thus reversing the legal supply circuit, as this drugs do not end dispensed to the public. This paper studies the risks to public health caused by these practices, detailing the results of health inspections in Galicia, where in relation to the total pharmaceutical establishments sanctioning procedures in the period 2011-2014, were sanctioned for this reason 15 community pharmacies and 5 distribution warehouses, the maximum fines belonging to a network consisting of a pharmaceutical distribution warehouse, with a 1,000,000 € fine and closure for 3 years, and 4 community pharmacies, with 2,400,000 € total fine; It also specifies the methodology of action, identifies the scene of illegal acquisition to make this trade with the greatest economic benefits, highlights the strengths of the success and further action to improve its approach.

Experiences with policing among people who inject drugs in Bangkok, Thailand: a qualitative study.

BACKGROUND: Despite Thailand's commitment to treating people who use drugs as "patients" not "criminals," Thai authorities continue to emphasize criminal law enforcement for drug control. In 2003, Thailand's drug war received international criticism due to extensive human rights violations. However, few studies have since investigated the impact of policing on drug-using populations. Therefore, we sought to examine experiences with policing among people who inject drugs (PWID) in Bangkok, Thailand, between 2008 and 2012. METHODS AND FINDINGS: Between July 2011 and June 2012, semi-structured, in-depth interviews were conducted with 42 community-recruited PWID participating in the Mitsampan Community Research Project in Bangkok. Interviews explored PWID's encounters with police during the past three years. Audio-recorded interviews were transcribed verbatim, and a thematic analysis was conducted to document the character of PWID's experiences with police. Respondents indicated that policing activities had noticeably intensified since rapid urine toxicology screening became available to police. Respondents reported various forms of police misconduct, including false accusations, coercion of confessions, excessive use of force, and extortion of money. However, respondents were reluctant to report misconduct to the authorities in the face of social and structural barriers to seeking justice. Respondents' strategies to avoid police impeded access to health care and facilitated transitions towards the misuse of prescribed pharmaceuticals. The study's limitations relate to the transferability of the findings, including the potential biases associated with the small convenience sample. CONCLUSIONS: This study suggests that policing in Bangkok has involved injustices, human rights abuses, and corruption, and policing practices in this setting appeared to have increased PWID's vulnerability to poor health through various pathways. Novel to this study are findings pertaining to the use of urine drug testing by police, which highlight the potential for widespread abuse of this emerging technology. These findings raise concern about ongoing policing practices in this setting.

Clinical use and control of the dispensing of thalidomide in Brasilia-Federal District, Brazil, from 2001 to 2012.

The use of thalidomide was never discontinued in Brazil where it is prescribed for leprosy type 2 reaction. Babies with birth defects compatible with the thalidomide embryopathy phenotype were born after 1965, an indication that control on drug dispensing and use failed in the country. The article reports data on thalidomide dispensing and clinical uses in the Federal District in 2011/12, when new rules were put into effect, and data on drug dispensing and use obtained ten years earlier. It was found that the number of patients making use of thalidomide declined from 819 in 2001 to 369 in 2011/12. Leprosy accounted for over 70% of prescriptions in both time periods analyzed in this study. In the same time interval, however, use for lupus erythematosus decreased from 13.7 to 4.9%, while that for multiple myeloma increased from 2.9 to 20.3% of all prescriptions. Thalidomide prescription for the remaining approved indications was far less frequent, and so was the use for off label indications that accounted for <1% of prescriptions in 2001 and 2011/12. Registration of prescribing doctors, patients and dispensing units at the state department of health, apparently rendered this control more effective and reliable.

O uso da talidomida nunca foi interrompido no Brasil, sendo prescrita para tratar a reação tipo 2 da hanseníase. Crianças com defeitos congênitos compatíveis com o fenótipo da embriopatia causada pela talidomida nasceram após 1965, evidenciando que o controle do uso e da dispensação do medicamento falhou no país. O artigo relata dados sobre a dispensação e usos clínicos da talidomida no Distrito Federal em 2011/12, quando a nova regulamentação passou a vigorar, e dados sobre a dispensação e uso do medicamento 10 anos antes. Os resultados mostraram que o número de pacientes que usaram talidomida decresceu de 819 em 2001 para 369 em 2011/12. A hanseníase foi a indicação clínica para mais de 70% das prescrições nos períodos analisados no estudo. No mesmo período, entretanto, o uso para lupus eritematoso reduziu de 13,7 para 4,9%, enquanto o uso para mieloma múltiplo cresceu de 2.9 para 20,3% de todas as prescrições. A prescrição de talidomida para as outras indicações aprovadas foi muito menor, enquanto para indicações não aprovadas correspondeu a < 1% das prescrições em 2001 e 2011/12. O cadastro dos prescritores, pacientes e unidades dispensadoras na secretaria estadual de saúde, aparentemente tornou esse controle mais eficiente e confiável.
