cannabis: A Pathfinder

This is a computer-generated pathfinder created against the Distant Reader study called cannabis.

Each Distant Reader study carrel is composed of many individual items. Each item is bibliographically described with author, title, date, summary, and keyword values. Below is a list of the items' most signficant keywords as well as lists of the items themselves. Purpusing the content of this pathfinder provides the student, researcher, or scholar with one way to get their heads around the scope of the carrel. The keywords include:

Use; Health; Marijuana; Participants; Alcohol; Students; Effects; Consequences; Motives; Age; Pain; Data; Time; Patients; Frequency; States; State; Tobacco; Control; Grams

Depending on how this pathfinder was created, many of the bibliographic sections will include elaborations on the meaning(s) of the given keywords. These elaborations were generated by feeding the items' summaries to a large langauge model and asking the model to address the question, "What is X?", where "X" is the keyword. The result will be a few sentences of elaboration. Be forewarned. The elaborations are often plausible, but they should not be take as truth. Instead, they should be taken as points for consideration.

• Development of Brief Alcohol and Cannabis Motives Measures: Psychometric Evaluation Using Expert Feedback and Longitudinal Methods by Bartel, Sara; Sherry, Simon ; Mahu, Ioan; Stewart, Sherry (2022) - Conclusions: The brief measures represent psychometrically-sound measures of cannabis and alcohol use motives with substantially less participant burden than the MMM and MDMQ-R. Key words: = cannabis motives; alcohol motives; test development; young adults Individuals are motivated to engage in cannabis and alcohol use to achieve a variety of effects (i.e., substance use motives). 2Based on publication history, 27 experts were considered to have expertise in both alcohol and cannabis motives; 21 were considered to have expertise in cannabis motives only; and 25 were considered to have expertise in alcohol motives only.

• Stress as a Moderator of the Effects of Coping Motives on Alcohol and Marijuana Use in Young Adulthood by White, Helene R.; Anderson, Kristen G.; Beardslee, Jordan (2018) - Crossover Analyses Table 3 shows the same main effects models for crossover effects, that is, marijuana motives predicting alcohol use and alcohol motives predicting marijuana use. Hierarchical regression analyses indicated that stronger alcohol coping motives were significantly related to greater frequency and quantity of alcohol use at ages 26 and 29 and stronger marijuana coping motives were significantly related to greater frequency of marijuana use at age 26 but not 29. Keywords: age; alcohol; coping; enhancement; frequency; marijuana; motives; stress; substance; use
• Discrepant Parent-Adolescent Reports of Parental Monitoring And Their Relations to Cannabis Use Among Justice-Involved Youth by Micalizzi, Lauren; Suazo, Nazaret; Paszek, Claudia; Hernandez, Lynn; Kemp, Kathleen; Jackson, Kristina; Spirito, Anthony (2022) - Key words: = cannabis use; juvenile justice; youth; parental monitoring; sources of parental knowledge The prevalence of past-year cannabis use (CU) increased among justice-involved youth (JIY) in recent years (Vaughn et al., 2020) and this trend is expected to continue as the cannabis legalization landscape evolves; as states continue to legalize adult CU, studies show corresponding increases in use among youth who had previous contact with the justice system (Kan et al., 2020). Parental monitoring and knowledge are two of the most frequently evidenced protective familial management strategies for youth substance use (Crouter & Head, 2002). Keywords: adolescent; cannabis; child; discrepancies; knowledge; model; monitoring; parent; reports; use
• Young Adults’ Knowledge of State Cannabis Policy: Implications for Studying the Effects of Legalization in Vermont by West, Julia C.; Peasley-Miklus, Catherine; Klemperer, Elias M. ; Priest, Jeffrey S.; Trutor, Megan; Carman, Chelsea; Roemhildt, Maria; Trites, Jeffrey; Villanti, Andrea C. (2022) - This study aimed to explore policy knowledge as another measure of exposure and describe the sociodemographic, cognitive, and behavioral correlates of cannabis policy knowledge in young adults in Vermont. In a series of multivariable analyses adjusting for age, sex, race and ethnicity, subjective financial status, and past-30-day cannabis use, young adults who reported slight risk of harm from weekly cannabis use had a higher prevalence of cannabis policy knowledge (aPR=1.28; 95% CI, 1.11-1.48) than those who reported no risk (Table 3).

• Parent and Adolescent Reports of Parental Monitoring and Sources of Parental Knowledge are Linked to Cannabis Use and Symptom Development in Adolescents by Parlette, Brianna; Treloar Padovano, Hayley; Pielech, Melissa; Meisel, Samuel; Miranda Jr., Robert (2022) - While most research relating parental monitoring to adolescent cannabis use relies solely on adolescent perceptions, our study suggests a unique role of parent perceptions for cannabis use and disorder symptoms, respectively. Thus, the distinction of parent-driven, active efforts to secure knowledge (i.e., solicitation and control) from child-driven processes (i.e., voluntary disclosure) is important for understanding which aspects of “monitoring” are protective against adolescent cannabis use and problem development.

• Novel Methods of Cannabis Use and Lower Sleep Duration Among High School Students by Winiger, Evan; Ma, Ming; Brooks-Russell, Ashley (2022) - High school (9th-12th grade) students from the Healthy Kids Colorado Survey with current cannabis use (n= 4,637) reported on numerous demographic variables, method of cannabis use (flower, edibles, dabs, and vaporizers) and average sleep duration on weeknights. Future studies should focus on specific type of high concentrate products (edibles, dabbing, vaping, etc.) on sleep outcomes and should also include longitudinal designs to better understand the influence of novel cannabis use on sleep during adolescence and into adulthood, and other possible health outcomes. Keywords: cannabis; cannabis use; methods; novel; sleep; students; use
• Local Laws Regulating Cannabis in California Two Years Post Legalization: Assessing Incorporation of Lessons from Tobacco Control by Padon, Alisa; Young-Wolff, Kelly; Avalos, Lyndsay; Silver, Lynn (2022) - There have been mixed findings on the effects of legalization on cannabis use among certain populations more vulnerable to harms such as youth, pregnant women and individuals at risk for cannabis use disorder (Ammerman et al., 2015; Anderson et al., 2019; Berg et al., 2018; Cerdá et al., 2017, 2019; Chu, 2014; Coley et al., 2019; Dilley et al., 2018; Schlienz & Lee, 2018; Shi, 2016; Stolzenberg et al., 2016), perhaps due in part to varied research methods and cannabis policy environments across the U.S. (Berg et al., 2018). In a 2017 meta-analysis, the National Academies of Science, Engineering and Medicine (NASEM) found substantial evidence supporting an association between cannabis use and serious harms such as psychosis, schizophrenia, and cannabis use disorder, among others, especially when use is initiated during adolescence and used frequently (National Academies of Sciences, Engineering, and Medicine, 2017).

• Offering an Alternative to Persons with Chronic Pain: How Access to Cannabis May Provide an Off-Ramp from Undesired Prescription Opioid Use by Bobitt, Julie ; Kang, Hyojung; Arora, Kanika; Bhagianadh, Divya; Milavetz, Gary; Kaskie, Brian (2023) - Patterns and correlates of medical cannabis use for pain among patients prescribed long-term opioid therapy. While the U.S. Food and Drug Administration has yet to approve cannabis use for medicinal purposes, the National Academies of Sciences, Engineering, and Medicine (2017) found substantial evidence that cannabis is an effective treatment for CP, and up to 80% of individuals who take medical cannabis report doing so to manage CP (Bonn-Miller et al., 2014; Keywords: alternative; cannabis; health; individuals; medical; opioid; pain; prescription; program; use
• Early Birds and Night Owls: Distinguishing Profiles of Cannabis Use Habits by Use Times with Latent Class Analysis by Hetelekides, Eleftherios ; Joseph, Verlin; Pearson, Matthew; Bravo, Adrian Jorge; Prince, Mark; Conner, Bradley (2022) - With regard to the auxiliary variables, morning and daily cannabis use classes reported lower use of protective behavioral strategies and greater scores on indicators of use, motives, related negative consequences, and perceptions/norms compared to weekend non- morning use classes. Alternatively, “wake and bake” is a colloquial term that refers to morning cannabis use and is integrated in the cannabis subculture, though “wake and bake” is discouraged by individuals who have been using cannabis for a long time (Lau et al., 2015). Keywords: cannabis use; class; classes; daily; datasets; latent class; marijuana; morning class; morning use; sample; study; use; use classes; weekend; weekend use
• Understanding Changes in Social Cannabis Use among Young Adults During the COVID-19 Pandemic: A Social Network Analysis by DiGuiseppi, Graham; Fedorova, Ekaterina ; Conn, Bridgid; Lankenau, Stephen; Davis, Jordan; Ataiants, Janna; Wong, Carolyn (2022) - Given that the traditionally social nature of cannabis use— whether for recreational or medical purposes— may run counter to social distancing recommendations, particularly among young adults and, whose cannabis use during the pandemic appeared to have increased (Boehnke et al., 2021; Fedorova et al., 2021; Graupensperger et al., 2021; Schepis et al., 2021), additional research is needed to better understand how social isolation and restriction resulting from a pandemic could significantly alter social cannabis use for young adult users. Among young adult college student cannabis users, social cannabis use was reported almost twice as often (7 days per month) than solitary cannabis use (4 days per month) on average (Buckner et al., 2016).

• Beyond the bong: Edible marijuana use among college students by Vidourek, Rebecca A.; King, Keith A.; Burbage, Michelle (2018) - The present study examines edible marijuana use among college students and attitudes towards use and legalization. Such high rates of edible marijuana use may be a cause for concern for health professionals. Keywords: edibles; health; marijuana; marijuana use; ohio; research; students; study; use; users
• Public Education Can Be Used to Increase Support for Equity in Cannabis Policy by Allen, Jane; Lee, Youn; Woodlea, Robyn; Malo, Vincenzo; Zitney, Lauren (2023) - Few participants (24.9%) were familiar with the concept of equity in cannabis policy, and a substantial proportion—from about 20% to 35%—provided a “neutral” or “don’t know” response when asked about support for specific policies. Exposure to an educational message was associated with greater perceived importance of equity in cannabis policy (p < 0.05) and greater support for equity-focused policies.

• Relationship Between Cannabis Use and Immediate, Delayed, and Working Memory Performance Among Older Adults by Maynard, Madison; Paulson, Daniel; Dunn, Michael; Dvorak, Robert (2023) - The primary limitation to this study was its sample size – although cannabis use was assessed among many respondents, cannabis use groups were largely variant in size. Past research identified cognitive effects of cannabis use among adolescents and young adults that can persist for several weeks after intoxication, though little is known about how these effects generalize to older adults. Keywords: adults; cannabis; cannabis use; effects; memory; use; users
• A Latent Variable Analysis of Psychomotor and Neurocognitive Performance After Acute Cannabis Smoking by Smith, Shelby; Julia Wrobel; Brooks-Russell, Ashley; Kosnett, Michael; Sammel, Mary (2023) - Linear regression models were utilized to quantify associations between factor scores and cannabis use groups (daily vs. occasional vs. no use). Key words: = factor analysis; cannabis use; drug tolerance; reaction time; neurocognitive and psychomotor performance; cannabis impaired driving With 38 U.S. states having legalized recreational and/or medicinal cannabis use, public policy related to cannabis impaired driving is of increasing significance.

• cannabis-309 by None (None) - Similarly, in the Canadian province of Ontario, exclusive use of ingestion- based methods of cannabis use increased among adults aged 18 years or older between 2017 and 2022, while exclusive use of inhalation-based methods decreased (Nigatu et al., 2024). These trends are concerning, as prior research characterizing the health effects of cannabis use has largely focused on smoking dried flower as the primary mode of cannabis use, while growing evidence suggests that cannabis-attributable harms vary by mode of use (Gunn et al., 2020; Russell et al., 2018; Steeger et al., 2021).

• Alcohol and Marijuana Polysubstance Use: Comparison of PTSD Symptom Endorsement and Severity Patterns by Kearns, Nathan T.; Cloutier, Renee M.; Carey, Caitlyn; Contractor, Ateka A.; Blumenthal, Heidemarie (2019) - Symptom Level Analyses Symptom level profile analysis for the PTSD intrusion symptoms indicated no main effect of substance use group (F[1,527] = 0.18, p = .672) and that parallelism between the groups was tenable (F[4,2108] = 0.48, p = .749). For example, only 3.4% of trauma-exposed participants in our larger sample (n = 1,029) reported only using marijuana in the past month (i.e., no alcohol or other substance use), meaning that any evaluation of “past-month marijuana use” participants would actually be overwhelmingly comprised of alcohol-marijuana polysubstance users.

• Chronic Marijuana Use, Inhibitory Control, and Processing Speed in Young Adult College Students by Cavalli, Jessica M.; Cservenka, Anita (2020) - Over the past two decades, there has been an overall decline in perceived harmfulness of MJ use in adults ages 18-30 (Schulenberg et al., 2018), despite growing evidence that chronic MJ use may be associated with cognitive impairment (Becker et al., 2014; Broyd et al., 2016; Crean et al., 2011; Yusoff et al., 2013). This study recruited young adults within a narrow age range in order to determine how MJ use may affect inhibitory control during the protracted maturation of executive functioning; to our knowledge, the current study is one of few studies that have examined chronic MJ use on inhibitory control during young adulthood (Crane, Schuster, & Gonzalez, 2013; Lisdahl & Price, 2012).

• The Relation Between Impulsivity and Estimation of Marijuana Weight by Parnes, Jamie; Kentopp, Shane; Sommerfeld, Joshua; Conner, Bradley (2021) - Most researchers would and do argue that when we measure marijuana use, we are attempting to measure the quantity of cannabinoids ingested, not how often marijuana is used (Freeman & Lorenzetti, 2020). Despite the importance of measuring both frequency and quantity consumed to depict marijuana use most accurately, as noted, most studies solely rely on reported frequency. Keywords: estimation; impulsivity; lack; marijuana; quantity; research; use
• Reasons for Marijuana Use and Its Perceived Effectiveness in Therapeutic and Recreational Marijuana Users Among People Living with HIV in Florida by Sajdeya, Ruba; Joseph, Verlin; Stetten, Nichole; Ibañez, Gladys; Wang, Yan; Powell, Lauren; Somboonwit, Charurut; Corsi, Karen; Cook, Robert (2021) - To our knowledge, our study is among the first to report self-scored marijuana effectiveness for different reasons for marijuana use among PLWH and the first to compare the reasons for use and the perceived effectiveness of marijuana across different groups of marijuana use motivation. Our research team developed and revised a questionnaire consisting of 25 items representing possible marijuana use reasons that demonstrate a range of social factors and physical and mental health symptoms and effects that are common among PLWH.

• Are Drinking Cognitions Associated with Marijuana and Concurrent Alcohol and Marijuana Use among Adolescents and Young Adults? by Pritschmann, Ricarda K.; Gebru, Nioud Mulugeta; Litt, Dana M.; Zhou, Zhengyang; Lewis, Melissa A. (2022) - Email: rpritschmann@ufl.edu Alcohol Cognitions and Substance Use 60 Unlike alcohol use, marijuana use has increased in the past decade among adolescents (ages 15 – 18 years) and young adults (ages 18 – 29 years; Johnston et al., 2020, Schulenberg et al., 2020). Research further indicates that marijuana use likely has a substitutionary and complimentary relation with alcohol use (O’Hara et al., 2016), but it is more likely that marijuana is used as a complement to alcohol among 14-20 year-olds (Pape et al., 2009).

• Assessing Cannabis Use Disorder in Medical Cannabis Patients: Interim Analyses from an Observational, Longitudinal Study by Sagar, Kelly; Dahlgren, Mary Kathryn; Smith, Rosemary; Lambros, Ashley; Gruber, Staci (2021) - Importantly, correlation analyses revealed that number of MC uses/week was not significantly correlated with total CUDIT-R scores, further supporting the idea that frequency of MC use is not likely a useful indicator of problematic use in MC patients, and raising questions regarding the validity of the CUDIT-R in those who use cannabis for medical purposes. We hypothesized that MC patients would exhibit increased frequency of use relative to baseline, but endorse few problems associated with MC use given their primary motivation for use is symptom alleviation.

• A Pilot Daily Diary Study of Changes in Stress and Cannabis Use Quantity Across the Menstrual Cycle by Hanzal, Nacera; Joyce, Kayla M.; Tibbo, Philip G.; Stewart, Sherry H. (2019) - Moreover, the fact that the difference in stress and cannabis use levels reported premenstrually were both relative to the ovulatory phase (and to the follicular phase in the case of cannabis use), points specifically toward the involvement of estrogen since it is estrogen that: begins increasing during the follicular phase, is highest during ovulation, and declines sharply during the premenstrual phase (Feher, 2012; Groome et al., 1996; Levy et al., 2000). Based on SRD (Levenson et al., 1980) and SMT (Khantzian, 1997) predictions, we also hypothesized that cannabis use quantity (during the first consumption episode following the stress assessment) would similarly increase in the menstrual and premenstrual phases versus other MC phases.
