Attitudes toward legalization of marijuana in the United States, 1986-2016: Changes in determinants of public opinion

Drug treatment courts and community-level crime

Research has recognized Adult Drug Treatment Courts (DTCs) as benefitting participants, with a wide body of research demonstrating lower levels of recidivism and drug use. A budding community-level body of research, however, has returned mixed results, some studies showing increases in arrests and crime relative to DTC initiation. Since DTCs cover over three-fourths of the US population, results showing such unintended consequences must be validated and rectified if held. This study estimated effects for DTCs for community-level crime effects from 1990 to 2018 using a stacked event study identification strategy. Most results indicated no significant effects. However, for population groups between 10,000 and 50,000, DTCs were associated with reductions in some crime categories. Violent index offenses offered the most robust results, and there was a small increase in non-index crimes in communities with populations between 50,000 and 100,000.

Public support for reinvesting resources from enforcing drug possession to health-promoting alternatives: A nationally representative poll of adults in the United States

BACKGROUND

The legal enforcement of drug possession is associated with a host of negative consequences for people who use drugs (PWUD), has demonstrated little effectiveness at curbing drug use, and has contributed to lasting financial, social, and health-related racial disparities in Black and Brown communities in the United States (U.S.). One policy alternative is reinvesting resources typically used for enforcing drug possession into health-promoting services such as drug treatment or harm reduction that can better serve the needs of PWUD than the criminal legal system. We sought to characterize the prevalence and correlates of national public support for this reinvestment in the U.S.

METHODS

A nationally representative sample of U.S. adults (N = 1,212) completed the Johns Hopkins COVID-19 Civic Life and Public Health Survey (wave three, fielded November 11-30, 2020). The outcome is support for reinvestment of resources spent on enforcing drug possession into health-promoting alternatives (i.e., drug treatment, harm reduction, housing support, or community-based resources). We measured potential correlates including socio-demographics and social/political attitudes, including political ideology (conservative, moderate, liberal) and racial resentment toward the Black community. Analyses accounted for complex survey weights.

RESULTS

Weighted prevalence of support for reinvestment of resources was 80 %. Multivariable logistic regression (controlling for confounders) showed that white respondents were more likely than Black (OR = 2.51, 95% CI = 1.08, 5.87) to favor reinvestment. Respondents with moderate (OR = 0.34, 95 % CI = 0.15-0.79) or conservative (OR = 0.21, 95 % CI = 0.09-0.50) political ideology (compared to liberal) and medium (OR = 0.26, 95 % CI = 0.09-0.74) or high (OR = 0.12, 95 % CI = 0.04-0.35) levels of racial resentment (compared to low) were less likely to support reinvestment.

CONCLUSION

There is substantial national support for reinvesting resources into health-promoting alternatives, though political ideology and racial resentment temper support. Results can inform targeted messaging to increase support for moving drug policy from the criminal legal sphere toward public health.

A Pragmatic, Person-Centered View of Cannabis in the United States: Pursuing Care That Transcends Beliefs

BACKGROUND

Rates of cannabis use are increasing in the United States, likely as a result of changes in societal attitudes and expanding legalization. Although many patients report wanting to discuss the risks and benefits of cannabis use with their clinical providers, many providers hold conflicting beliefs regarding cannabis use and often do not engage patients in discussion about cannabis. This dilemma is underscored by the limitations imposed on cannabis related research, and lack of empirically based best-practice guidelines for clinicians when addressing cannabis use with patients.

OBJECTIVES

We aimed to briefly summarize clinician and patient attitudes toward cannabis use and review current clinical guidelines and provide suggestions to assist health care providers and clinicians in increasing their comfort and skill in discussing cannabis use with patients.

METHODS

A narrative review on attitudes toward cannabis use and clinical guidelines was performed to summarize the literature and provide evidence-based recommendations.

RESULTS

Attitudes toward cannabis use have been shaped by personal and political factors and contribute to clinician hesitance in speaking with patients about the topic. Administrative barriers have hindered the development of clearer public health guidelines that might enable the dissemination of evidence-based information on the health effects of cannabis use and might ultimately lead to better health outcomes.

CONCLUSION

Not discussing cannabis use with patients may be a crucial missed opportunity for harm reduction. In the absence of empirically supported best-practice guidelines, a person-centered approach can facilitate conversations on the harms and benefits of cannabis use.

The effects of race and class on community-level stigmatization of opioid use and policy preferences

BACKGROUND

With opioid use and overdose rates continuing to plague minority communities in the U.S., we explored whether a geographic community's racial composition and social class affect how opioid use in the community is stigmatized and what policy preferences arise in response.

METHODS

We use case vignettes in a randomized, between-subjects study (N = 1478) with a nation-wide survey. The vignettes describe a community where opioids are harmfully used, varying whether the community was (1) wealthy or poor, (2) predominantly Black or White and (3) facing prevalent use of painkillers or heroin. We tested how these variables affect public stigmatization of opioid use (measured with ratings of responsibility, dangerousness, sympathy, concern, anger, and disappointment) preferred levels of social distance from communities with opioid use (measured with responses to questions about living, working, and interacting in the community), and policy preferences for responding to opioid use (measured with levels of support for providing a safe-consumption site in the community, treating drug use in the community punitively, treating drug use in the community as an illness, and funding drug treatment in the community through income redistribution).

RESULTS

Compared to wealthy communities with opioid use, poor communities with opioid use were less stigmatized in terms of responsibility, sympathy, concern, anger, and disappointment; they were also met with less support for punitiveness, more support for treating drug use as an illness, and preferences for greater social distance. Compared to White communities with opioid use, Black communities with opioid use were less stigmatized in terms of responsibility, and they were met with stronger preferences to not live and work there and with reduced support for using income redistribution to provide drug treatment for people in the community. Poor-Black communities with opioid use were also perceived to be more dangerous than both poor-White and wealthy-Black communities with opioid use.

CONCLUSION

These results point to class- and race-based territorial stigma affecting how communities with opioid use are judged and whether policies for providing communities with treatment are supported.

The political economy of a failed drug reform: Insights from Peru's main legal coca valley

As the world's second largest coca producer, Peru has a flourishing market for coca for non-narcotic uses. With more than 20,000 hectares and approximately 35,000 officially registered farmers in the Peruvian legal scheme for coca cultivation and commercialization, this market is formally under the monopoly of the National Enterprise of Coca (ENACO). Nonetheless, ENACO only captures 2% of all coca produced nationally and has experienced a sustained reduction of farmers' participation and coca purchases within the legal trade. At different times, these problems have opened the way to demands from left-wing political parties, subnational governments, coca growers' organizations and even Peru's central drug control institutions to reform the legal coca market in Peru. However, none of these attempts have succeeded. Based on a policy analysis of the legal coca trade and analysis of official data, together with a case study of Peru's main legal coca valley (La Convención) this article seeks to understand the current crisis of the legal coca trade as well as the repeated failures of reform. Peru's political centralism and the historical marginalization of Andean culture help to explain the successful blocking of reform attempts to the legal coca trade.

Impacts of recreational cannabis legalization on use and harms: A narrative review of sex/gender differences

Legalization of cannabis use for non-medical (recreational) purposes is changing the global cannabis landscape. As attitudes toward cannabis use become more positive and prevalence of use increases in complex ways, concerns emerge about the potential for increased cannabis-attributable harms. Understanding the who, why, and when of this likely increase in cannabis-attributable harms is thus an important public health priority. Both sex and gender contribute to variability in the use, effects, and harms of cannabis and thus sex/gender considerations are important when evaluating the impacts of cannabis legalization. The goal of this narrative review is to broadly discuss sex/gender differences in attitudes toward and prevalence of cannabis use, whether there are sex/gender differences in the impacts of cannabis legalization, and why these sex/gender differences might exist. One of our strongest conclusions is that men have always been more likely to use cannabis than women, yet the sex/gender gap in prevalence of cannabis use has narrowed over time, and this might be partly due to cannabis legalization. The existing evidence suggests that there have also been sex/gender differences in the impacts of legalization on cannabis-attributable harms such as cannabis-involved motor vehicle collisions and hospitalizations, though these results are more variable. The body of literature reviewed has focused almost exclusively on samples of cisgender research participants, and thus future research should encourage inclusion of transgender and gender-diverse participants. More consideration of sex- and gender-based analysis in research evaluating long-term impacts of cannabis legalization is a clear research priority.

A Scoping Review of Risk and Protective Factors for Negative Cannabis Use Consequences

Objective

Numerous reviews have examined risk and protective factors for alcohol-related negative consequences, but no equivalent review of risk and protective factors exists for cannabis-related negative consequences (CRNCs)-a gap filled by the present study. This scoping review examined survey-based research of risk and protective factors for CRNCs such as neglecting responsibilities, blacking out, or needing more cannabis.

Methods

Three databases (PubMed, PsycINFO, and Google Scholar) were searched for peer-reviewed manuscripts published between January 1, 1990, and December 31, 2021. A qualitative synthesis was performed using the matrix method and the results were organized using the socioecological model as a framework.

Results

Eighty-three studies were included in the review. There was considerable variation in measures and operationalizations of CRNCs across studies. Risk factors were identified in the intrapersonal (depression, social anxiety, PTSD, impulsivity, sensation seeking, motives, expectancies), interpersonal/community (trauma, victimization, family and peer substance use, social norms), and social/policy (education, employment, community attachment, legalization, availability of substances) domains of influence. Protective behavioral strategies were a robust protective factor for CRNCs. Males consistently reported more CRNCs than females, but there were no differences observed across race.

Conclusions

Future research should identify person- and product-specific patterns of CRNCs to refine theoretical models of cannabis misuse and addiction. Public health interventions to reduce the risk of negative consequences from cannabis should consider utilizing multilevel interventions to attenuate the cumulative risk from a combination of psychological, contextual, and social influences.

Depressive symptoms faced by non-native international medical students in China during COVID-19

This study examines depressive symptoms faced by non-native international medical students studying in China during the COVID-19 pandemic. The targeted population for this cross-sectional study included non-native medical students studying in Chinese universities. This study used convenience sampling. An online, self-administered questionnaire was distributed to international medical students studying in Chinese universities from February 2020 to June 2021. The questionnaire collected demographic data, information regarding struggles faced, and used the CES-D-10 Likert scale to assess both the challenges and depression symptoms, respectively. By analyzing the 1,207 students’ responses, the study found that students with poor Chinese language were two times more likely to suffer from depressive symptoms (OR = 2.67; value of p 0.00). Moreover, female students were found more prone (76.35%) than their male counterparts (44.96%). The study found that food adaptability, health issues, accommodation issues, and financial issues were related factors contributing to depressive symptoms among non-native international medical students during the COVID-19 pandemic. The study tried to highlight the factors that resulted in depressive symptoms among non-native international medical students, and the findings may help diplomatic representatives take necessary actions to help their citizens during this difficult time.

Sharing pro-marijuana messaging on social media: The moderating role of legislation

ObjectivesThis study investigates whether recreational marijuana legislation and perceived social norms (descriptive and injunctive) affect college students' propensity to share pro-marijuana messages. We examine which referent group (close friends, typical student, parents) most influence those norms. Participants: A sample of 343 college students participated in the study. Of these students, 214 were from Washington State, where recreational marijuana is legal, and 129 were from Wyoming, where recreational marijuana is illegal. Method: Data, from an online survey, were analyzed through PROCESS analyses. Results: College students in Washington State who believed a typical peer would want them to share pro-marijuana messaging were marginally more likely to share pro-marijuana messages than their counterparts in Wyoming. However, among students who thought a typical peer would not approve of them sharing pro-marijuana messaging, the opposite pattern emerged. Conclusion: Restrictive recreational marijuana legislation does not uniformly abate related message sharing on social media.

Attitudes in 2020 Towards Medical and Recreational Marijuana in Prohibitionist Nebraska

Despite considerable change in the legal status of marijuana in the United States in the 21st century, the state of Nebraska has become an outlier in maintaining a complete prohibition on the substance. We estimate overall public support for medical and recreational marijuana in the state of Nebraska. Our data comes from the 2020 Nebraska Annual Social Indicators Survey, an address-based sample of Nebraskan adults. We asked a question from the Pew Research Center if participants support legal marijuana for medical AND recreational use, medical use only, or if they think it should not be legal. We estimate that 83.18% of Nebraskans support medical marijuana legalization. There is less consistent support for legal recreational use than medical use alone. There are also associations between support preferences and age, political party, gender, and the amount of stigma a participant reports in their community towards people that use various substances.

Acceptance towards decriminalization of medical marijuana among adults in Selangor, Malaysia

Introduction

The issue of decriminalization of medical marijuana has gained public attention globally due to the decisions of various governments in developed and developing countries who have decriminalized marijuana for medical purposes. The action was the result of the change in perception towards medical marijuana use, which is now believed to be safe, acceptable, and should be decriminalized. Due to the progress of modernization and the wide access to information, the change in perception towards medical marijuana seems to be inevitable and might have already permeated among the public in Malaysia. However, at the moment there is no baseline data to determine any of this claim.

Objective

To determine the prevalence and factors associated with acceptance towards decriminalization of medical marijuana among adults in Selangor, Malaysia.

Methodology

The study was a cross-sectional study conducted in year 2021 among 462 adults aged 18 years old and above in Selangor, Malaysia. The respondents were sampled using a multistage random sampling. The data was collected via self-administered questionnaires and has been analyzed using SPSS version 25.

Result

More than half of the respondents in this study (64.7%) show acceptance towards the decriminalization of medical marijuana in Malaysia. The results of statistical tests indicate that there are significant associations between age (p < 0.001), gender (p = 0.005), ethnicity (p < 0.012), level of education (p < 0.011), employment status (p = 0.001), ever smoked (p < 0.001), given up smoking (p = 0.002), ever used substance (p < 0.001), current substance use (p < 0.001), given up substance (p < 0.001), exposure to medical marijuana-related content (p < 0.001), perceived risk associated with medical marijuana use (p < 0.001), perceived risk of harm of medical marijuana use (p < 0.001), and perceived approval of medical marijuana use (p < 0.001) with acceptance towards decriminalization of medical marijuana. The predictors for acceptance towards decriminalization of medical marijuana are perceived high approval of medical marijuana use (aOR = 7.023, p < 0.001, 95%CI = 3.534,13.955), perceived low risk of medical marijuana (aOR = 5.716, p < 0.001, 95%CI = 2.828,11.554), perceived low risk of harm from medical marijuana use (aOR = 3.480, p = 0.001, 95%CI = 1.702,7.114), current substance use (aOR = 2.264, p = 0.050, 95%CI = 1.001,5.118), and ever used substance (aOR = 2.005, p = 0.004, 95% CI = 0.054,0.576).

Conclusion

The results of the survey show that the current acceptance level towards decriminalization of medical marijuana is considerably high. However, the acceptance is mainly among those who are exposed to the substance and those who perceive low risk of medical marijuana. Thus, a further exploration of this phenomenon is needed, especially by increasing the sample size and expanding the study location to other states.

A Systematic Review of Trends in US Attitudes toward Cannabis Legalization

METHODS

A systematic search was conducted for publications in PubMed, EMBASE, and PsycINFO up to October 2019. Six studies with a regionally or nationally representative adult US-based populations were included. A secondary analysis was conducted using data from the National Survey of Drug Use and Health. Hierarchical age-period-cohort analysis assessed the trends in perceived harmfulness and availability of cannabis between 1996 and 2018. Ecological comparisons were made between these perceptions and support for cannabis legalization over time.

RESULTS

A steep growth in support for cannabis legalization began in the 1990s and continued to grow in a relatively linear manner. Most people developed more liberal views, with no evidence that changes within any one sociodemographic group was disproportionately responsible for the overall attitudinal change. Increases in the proportion of people who use cannabis, non-religious population and political liberalism may partially explain the increased support for legalization. The decline in perceived harmfulness of cannabis, as reflected in the media, may have contributed to the increased support for legalization. However, perceptions of the availability of cannabis remained stable despite significant relaxations in cannabis regulations.

CONCLUSIONS

The US population has become more accepting of cannabis legalization. The attitudinal change is related to changes in the perceived risks and benefits of cannabis use, influenced by broader political and cultural changes over the study period.

Bioethical insights from the Fiqh Council of North America's recent ruling on medical cannabis

There is growing momentum to legalize medical cannabis across the United States. Positive public attitudes and permissive policies are based on growing anecdotal experiences and medical evidence that enumerate the health benefits of cannabis. Against this backdrop, Muslim stakeholders are (re)-evaluating their stance on the issue for Muslim patients who may benefit from such novel treatments, Muslim physicians who could incorporate the provision of cannabis into practices, and Muslim entrepreneurs who may seek to engage with the pharmaceutical and business aspects of the growing industry. Given this renewed interest, the Fiqh Council of North America (FCNA), a deliberative body comprised of Islamic jurists and medical consultants, examined the medical as well as religious evidence surrounding medical cannabis in order to furnish Muslim Americans with religious guidance. In 2018, they resolved that, while the use of intoxicating substances is proscribed by Islamic law, medical cannabis was permissible for Muslims to use with the following stipulations: Non-psychoactive preparations of cannabis are permitted to treat illnesses for which therapeutic effects of cannabis are certain, and psychoactive preparations are contingently permissible in cases of dire necessity. In this paper we first discuss the deliberative process and ethico-legal rationale brought to bear in furnishing the ruling, and then proceed to critically examine its conceptual gaps, practical limitations, and future implications. Clarifying the nuances around the religious permissibility of medical cannabis is important for Muslim patients and providers whose attitudes and behaviors may be informed by the ruling, as well for stakeholder groups within pharmaceutical and health policy circles who aim to address the needs of the global Muslim community that may stand to benefit from advances in medical cannabis research and therapeutics.

Public health impacts to date of the legalisation of medical and recreational cannabis use in the USA

The legality of cannabis use has been changing in a number of jurisdictions around the world. In the U.S., it has been legalised for medicinal and/or recreational uses in 34 jurisdictions and counting. This study leverages the decades-long experience of legalisation in the U.S. to provide an overview of the associated changes in public attitudes, cannabis markets and adverse health effects. We found a broad-based warming of public attitudes toward legalisation, potentially influenced by the increasingly positive portrayal of cannabis in media and declines in cannabis risk perceptions. Potency of cannabis products increased significantly while prices fell sharply. Although adults were less responsive to price changes than adolescents, adults who use cannabis regularly were sensitive to prices, with an estimated 10% price reduction leading to about 2.5% increase in the rate of use. Overall, past-year cannabis use has increased in adults since 2002, and adults over 26 years old who resided in states with medicinal cannabis laws were more likely to have used cannabis in the past 30 days, to have used daily, and to have higher rates of cannabis use disorders than adults who resided in states without legalised medicinal cannabis. Traffic fatalities involving cannabis temporarily increased in some states post-legalisation, and there were more presentations to medical services related to chronic regular cannabis use. There is suggestive evidence that adverse health consequences have increased among people who use cannabis regularly since legalisation. More robust research is needed to determine whether these effects of legalisation are temporary or long-term.

Emerging Use of Epidiolex (Cannabidiol) in Epilepsy

The first plant-derived, purified pharmaceutical-grade cannabidiol (CBD) medication, Epidiolex, was approved in the United States by the FDA on June 25, 2018. Its approval for patients ≥ 2 years of age with Dravet syndrome (DS) or Lennox-Gastaut syndrome (LGS) markedly altered the treatment of medically refractory seizures in these disorders. This state-of-the-art review will discuss the history of CBD, its current pharmacology and toxicology, evidence supporting its use in a variety of epileptic syndromes, common side effects and adverse effects, and pharmacokinetically based drug-drug interactions. Owing to the importance in considering side effects, adverse effects, and drug-drug interactions in patients with medically refractory epilepsy syndromes, this review will take a deeper look into the nuances of the above within a clinical context, as compared to the other antiepileptic medications. Furthermore, despite the limited data regarding clinically significant drug-drug interactions, potential pharmacokinetic drug-drug interactions with CBD and other antiepileptics are theorized on the basis of their metabolic pathways. The article will further elucidate future research in terms of long-term efficacy, safety, and drug interactions that is critical to addressing unanswered questions relevant to clinical practice.

Facing the option for the legalisation of cannabis use and supply in New Zealand: An overview of relevant evidence, concepts and considerations

ISSUES

Non-medical cannabis policies are changing, including towards legalisation-with-regulation frameworks. New Zealand will hold a public referendum on cannabis legalisation in 2020. We reviewed data on cannabis use and health/social harms; policy reform options; experiences with and outcomes of reforms elsewhere; and other relevant considerations towards informing policy choices in the upcoming referendum.

APPROACH

Relevant epidemiological, health, social, criminal justice and policy studies and data were identified and comprehensively reviewed.

KEY FINDINGS

Cannabis use is common (including in New Zealand) and associated with risks for health and social harms, mainly concentrated in young users; key harms are attributable to criminalisation. 'Decriminalisation' reforms have produced ambivalent results. Existing cannabis legalisation frameworks vary considerably in main parameters. Legalisation offers some distinct advantages, for example regulated use, products and user education, yet outcomes depend on essential regulation parameters, including commercialisation, and policy ecologies. While major changes in use are not observed, legalisation experiences are inconclusive to date, including mixed health and social outcomes, with select harms increasing and resilient illegal markets. It is unclear whether legalisation reduces cannabis exposure or social harms (e.g. from enforcement) for youth.

IMPLICATIONS/CONCLUSIONS

No conclusive overall evidence on the outcomes of legalisation elsewhere exists, nor is evidence easily transferable to other settings. Legalisation offers direct social justice benefits for adults, yet overall public health impacts are uncertain. Legalisation may not categorically improve health or social outcomes for youth. Legalisation remains a well-intended, while experimental policy option towards more measured and sensible cannabis control and overall greater policy coherence, requiring close monitoring and possible adjustments depending on setting-specific outcomes.

Characteristics of Older Adults Who Were Early Adopters of Medical Cannabis in the Florida Medical Marijuana Use Registry

Use of medical marijuana is increasing in the United States and older adults are the fastest growing user group. There is little information about the characteristics and outcomes related to medical marijuana use. This study is a descriptive analysis of older adults (aged ≥50 years old) who were early adopters of a medical marijuana program in the U.S. state of Florida. Per state legislation, initial and follow-up treatment plans were submitted to the University of Florida College of Pharmacy. Data collection included demographics, clinical history, medical conditions, substance use history, prescription history, and health status. Follow-up treatment plans noted changes in the chief complaint and actions taken since the initial visit. Of the state's 7548 registered users between August 2016 and July 2017, N = 4447 (58.9%) were older adults. Patients utilized cannabidiol (CBD)-only preparations (45%), preparations that had both tetrahydrocannabinol (THC) and CBD (33.3%) or were recorded to use both CBD-only and THC + CBD products (21.7%). The chief complaints indicating medical cannabis treatment were musculoskeletal disorders and spasms (48.4%) and chronic pain (45.4%). Among other prescription medications, patients utilized antidepressants (23.8%), anxiolytics and benzodiazepines (23.5%), opioids (28.6%), and cardiovascular agents (27.9%). Among all drug classes with potential sedating effects, 44.8% of the cohort were exposed to at least one. Patients with follow-up visits (27.5%) exhibited marked improvement as assessed by the authorizing physicians. However, the patient registry lacked detailed records and linkable information to other data resources to achieve complete follow up in order to assess safety or efficacy. Future improvements to registries are needed to more adequately capture patient information to fill knowledge gaps related to the safety and effectiveness of medical marijuana, particularly in the older adult population.

Potential Adverse Drug Events with Tetrahydrocannabinol (THC) Due to Drug-Drug Interactions

Tetrahydrocannabinol (THC) is the primary psychoactive ingredient in cannabis. While the safety of THC and cannabis has been extrapolated from millennia of recreational use, medical marijuana programs have increased exposure among medically complex individuals with comorbid conditions and many co-prescribed medications. Thus, THC should be recognized as a pharmacologically complex compound with potential for drug–drug interactions and adverse drug events. This review summarizes potential adverse drug events related to THC when combined with other medications. Metabolic drug–drug interactions are primarily due to THC conversion by CYP3A4 and CYP2C9, which can be impacted by several common medications. Further, CYP2C9 polymorphisms are highly prevalent in certain racial groups (up to 35% in Caucasians) and increase the bioavailability of THC. THC also has broad interactions with drug-metabolizing enzymes and can enhance adverse effects of other medications. Pharmacodynamic interactions include neurological effects, impact on the cardiovascular system, and risk of infection. General clinical recommendations for THC use include starting with low doses and titrating to desired effects. However, many interactions may be unavoidable, dose-limiting, or a barrier to THC-based therapy. Future work and research must establish sufficient data resources to capture medical marijuana use for such studies. Meanwhile, clinicians should balance the potential risks of THC and cannabis and the lack of strong evidence of efficacy in many conditions with patient desires for alternative therapy.
