Despite the effectiveness of PBS in reducing both cannabis use and negative cannabis-related consequences, few studies have examined whether there are sex and cultural differences in PBS use. In the present study, we compare PBS use across males and females and across five countries. We also examine whether the associations of PBS use with cannabis-related outcomes differ by sex and country. We recruited 1,175 college students (63.3% female; Mage = 20.96, SD = 3.95; 45.1% Freshman, 20.2% Sophomore, 16.6% Junior, 9.7% Senior, 8.4% other) who reported past-month cannabis use from eight universities in five countries (U.S., Spain, Argentina, Uruguay, and the Netherlands) to complete an online survey. The online survey included the Marijuana Use Grid (MUG; Pearson & Marijuana Outcomes Study Team, 2020), Protective Behavioral Strategies for Marijuana scale (PBSM; Pedersen et al., 2016; revised by Pedersen et al., 2017), and Brief-Marijuana Consequences Questionnaire (B-MACQ; Simons et al., 2012). Results of a series of ANOVAs suggested differences across countries on the PBSM total score, F(4, 1,126) = 20.93, p < .001, such that participants in the U.S. (M = 4.53, SD = 1.11) and Spain (M = 4.48, SD = 0.95) endorsed the most frequent PBS use and participants in the Netherlands (M = 3.46, SD = 1.49) endorsed the least frequent PBS use. There were many item-level differences in PBS use across countries with a pattern similar to that for the PBSM total score. Results of a series of independent sample t-tests suggested that females (M = 4.51, SD = 1.11) scored higher than males (M = 4.17, SD =1.09) on the PBSM total score, t(1,123) = -4.88, p < .001, as well as nearly every item. The correlations between PBSM total score and cannabis-related outcomes across gender and countries were mostly in the expected direction: more frequent PBS use was associated with less cannabis use and fewer cannabis-related consequences. These correlations were largest for the U.S. sample. Interestingly, however, the correlation between the PBSM total score and B-MACQ was positive for the Argentina sample and every correlation between the PBSM total score and cannabis-related outcome was positive for the Netherlands sample. The results of the present study suggest there are several gender and cultural differences in the use of cannabis-related PBS. However, future studies are needed to replicate these findings, especially given the relatively small samples for some of the countries in the present study (our smallest sample size was for Uruguay [n = 46]). Gender and cultural differences in PBS use should be considered in developing and tailoring PBS interventions, especially because the PBSM was validated with a U.S. sample and most existing interventions were developed for use with U.S. participants.","PeriodicalId":383892,"journal":{"name":"Abstracts from the 2020 Virtual Scientific Meeting of the Research Society on Marijuana July 24th, 2020","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131614453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research on the links of PMS to problematic substance use has largely omitted consideration of cannabis use. Design/Method: To fill these gaps, 87 cannabis using women (mean age = 28.9 years) completed a cross-sectional survey involving self-reports on their PMS symptoms on the Pre-Menstrual Scale – Short Form (PMS-SF), their usual motives for cannabis use on the Marijuana Motives Measure (MMM), their frequency of cannabis use in the last 30 days on the Cannabis Timeline Followback (C-TLFB), and their level of cannabis use problems on the Cannabis Use Disorder Identification Test (CUDIT). Analyses/Results: A series of multiple regressions were performed, along with Sobel tests of indirect effects, to examine the potential mediational role of cannabis motives in explaining the expected links of PMS symptoms with cannabis use frequency and problems. Separate models were run with cannabis use frequency and problems as outcomes, and with PMS affective and physiological symptoms as predictors. In each case, both coping motives and social motives (as a control to determine specificity) were tested as simultaneous mediators. PMS Affective (but not Physiological) symptoms were indirectly positively related to both cannabis use frequency and problems through Coping (but not Social) motives for use (Sobel tests = 2.01 and 2.26, respectively, p’s < .05). Discussion: Findings suggest that it is the affective symptoms of PMS (e.g., depressed mood), rather than the physiological symptoms (e.g., bloating, pain), that drive more frequent and problematic cannabis use in women. Moreover, the mechanism to explain this link appears to be coping (but not social) motives for cannabis use. Thus, those women with greater levels of PMS affective symptoms appear to use cannabis more frequently and problematically than other women by way of their greater use of cannabis to cope with negative mood.","PeriodicalId":383892,"journal":{"name":"Abstracts from the 2020 Virtual Scientific Meeting of the Research Society on Marijuana July 24th, 2020","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124651149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PTSD-cannabis relationship is important as cannabis use can worsen PTSD outcomes. Cannabis use motives are a useful construct for understanding the PTSD-cannabis relationship. Frequent pairing of a trauma cue with substance use to cope can lead to conditioned substance craving. The extant research has not yet examined potential mechanisms to explain this effect. We recruited 51 cannabis users with a trauma history for a cannabis cue-reactivity study to examine coping motives as a potential mediator of the hypothesized relationship between PTSD symptoms and cannabis craving to trauma cues. Participants first completed a validated cannabis use motives measure. They were then exposed to a personalized audio and visual cue based on their trauma experience and reported on their cannabis craving immediately following using a standardized measure. Coping motives were contrasted with enhancement motives as the mediator. Results supported our first hypothesis: PTSD symptoms were associated with increased cannabis craving following personal trauma cue exposure. However, our second hypothesis of an indirect effect through coping motives was not supported. We did find an independent main effect of coping motives on cannabis craving triggered by trauma cue exposure. The lack of an interaction between PTSD symptoms and coping motives on trauma-cue induced craving is potentially due to other factors we did not examine that help strengthen the relationship (e.g., sleep). These findings have important clinical implications for targeting both PTSD symptoms and coping motives to prevent the development of conditioned cannabis craving to trauma reminders.","PeriodicalId":383892,"journal":{"name":"Abstracts from the 2020 Virtual Scientific Meeting of the Research Society on Marijuana July 24th, 2020","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124016589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We developed a 13 item measure designed to characterize the 11 symptoms of CUD as described in the DSM 5 (APA, 2013). To evaluate the performance of this Self Reported Symptoms of Cannabis Use Disorder (SRSCUD) measure, we examined its associations with other measures of CUD symptoms, negative cannabis related consequences, and other known risk factors for CUD (i.e., coping motives). Colleges students (n =7000) recruited from 9 universities in 9 states throughout the U.S. Our analyses focus on past month cannabis users (n = 2077). We split our sample in half to conduct exploratory factor analysis (EFA,n = 1011) and confirmatory factor analysis (CFA, n = 1012). All items loaded saliently on a single factor of CUD symptoms in both EFA (.553 = λ = 805) and CFA models (.524 = λ = 830) (see Table 1). In our final model, we allowed correlated errors between the two indicators of tolerance (items 10 and 11) and the two indicators of withdrawal (items 12 and 13), and obtained acceptable model fit across most indices: CFI = .941, TLI = .927, RMSEA = .059, SRMR = .042. As shown in Table 2, the total score of the SRSCUD was strongly correlated with other CUD symptoms measures (.617 < r s < .697), demonstrating convergent validity. SRSCUD was moderately positively correlated with a well known risk factor for CUD (coping motives) and moderately negative correlated with a well known protective (cannabis protective behavioral strategies). We conducted receiver operator characteristic (ROC) curve analyses to identify well how our continuous measure of CUD symptoms could identify individuals who exceed the cutoffs for probable CUD on these other symptom measures. For the most well validated measure (CUDIT R), we had excellent sensitivity/specificity (mean score of 1.5 on SRSCUD) for predicting probable CUD. Although more research evaluating performance of the SRSCUD compared to a clinical diagnosis is needed, we have preliminary evidence for construct validity of this measure.","PeriodicalId":383892,"journal":{"name":"Abstracts from the 2020 Virtual Scientific Meeting of the Research Society on Marijuana July 24th, 2020","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133492100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although legalization of cannabis might give users a better sense of the quantity purchased and THC/CBD composition of products, issues in assessment and measurement can still preclude researchers from understanding use patterns. Given these challenges, the present work examines whether an individual’s average level of intoxication after cannabis consumption might serve as a better proxy for cannabis use than quantity of use. Data was aggregated from several studies related to cannabis use and health behaviors and collapsed across common variables (N = 2,659, Mean age = 34.08, 61.9% Male, 84.8% Caucasian). Our sample reported using cannabis either six or seven days per week, consuming approximately 1.12 ounces of cannabis per month (SD = .35 ounces), attaining an average intoxication of 3.49 on a scale from 0 (“Not at all”) to 6 (“Extremely high;” SD = 1.21), and experiencing a mild amount of cannabis-induced impairment as measured by the Cannabis-Associated Problems Questionnaire (CAPQ; M = 8.21, SD = 9.08). In this sample of frequent users, average intoxication levels were significantly related to cannabis problems (r = .153, p < .001) while quantity per month appeared to be unrelated (r = .005, p = .798). Using Meng’s (1992) procedure for comparing correlated correlation coefficients, these relations were found to significantly differ from each other (Z = - 5.53, p < .001). Our results provide preliminary evidence supporting cannabis-induced intoxication as a better proxy for cannabis use than quantity consumed. Individuals might more accurately remember their experiences of being high as opposed to recalling how much they consumed over a month’s span. Future work should continue to examine relations between intoxication and other indices of cannabis use to confirm and extend our findings.","PeriodicalId":383892,"journal":{"name":"Abstracts from the 2020 Virtual Scientific Meeting of the Research Society on Marijuana July 24th, 2020","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126972310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yakovenko","doi":"10.26828/cannabis.2021.01.000.19","DOIUrl":"https://doi.org/10.26828/cannabis.2021.01.000.19","url":null,"abstract":"Background and aim: A robust association exists between substance use and personality, with personality risk factors representing phenotypes of vulnerability to substance misuse. As such, personality risk factors may be valuable constructs for understanding specific motivations for substance misuse. Given the loosening of restrictions on cannabis worldwide, research focusing on understanding cannabis use in young adults, a particularly at-risk population, remains a vital area of research. The existing data provides extensive support for the mediating role of coping motives on personality risk factors and problematic cannabis use; however, the role of other types of motives has remained largely unexplored. Our study examined the mediating role of cannabis use motives between personality and cannabis misuse among university students. We also explored the predictive value of personality phenotypes for cannabis use problems. Research question and hypothesis: Do motivations for cannabis use mediate or explain the relationship between personality type and cannabis use problem severity? Hypothesis 1: sensation-seeking (SS) and impulsivity (IMP), but not anxiety sensitivity and hopelessness, will be associated with greater cannabis use problem severity. Hypothesis 2: motives for use (i.e., coping, conformity, social, enhancement, expansion) will mediate the association between personality risk and cannabis use problem severity. Method: A survey was administered to 1073 undergraduate students. We examined whether motivations for use (mediator variable) explained the relationship between personality (predictor variable) and cannabis use disorder severity (outcome variable) using an ordinary least-squares (OLS) based mediation analysis. Results: As hypothesized, SS and IMP predicted greater cannabis use problems. A noteworthy finding was that conformity motives were a significant mediator between SS and IMP and cannabis use, whereby higher levels of SS/IMP led to greater endorsement of conformity motives, which in turn led to lower cannabis misuse. Enhancement motives were also a significant mediator between IMP and cannabis use. Expansion motives were a significant mediator between SS and cannabis use. Conclusion: Understanding reasons for use (i.e., motives) allows us to identify those at greatest risk for cannabis misuse. Findings from this study may help explain the underlying mechanisms by which personality risk factors lead to cannabis use disorder in young adults. A greater understanding of these personality phenotypes may have implications for the development of personality-specific interventions for cannabis use.","PeriodicalId":383892,"journal":{"name":"Abstracts from the 2020 Virtual Scientific Meeting of the Research Society on Marijuana July 24th, 2020","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128879722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simon, James Murphy","doi":"10.26828/cannabis.2021.01.000.32","DOIUrl":"https://doi.org/10.26828/cannabis.2021.01.000.32","url":null,"abstract":"Cannabis is the most commonly used illicit drug in the US and appears to have an indirect effect on dopamine (DA) output in the mesolimbic projection, a circuit implicated in reward processing and effort expenditure. Thus, some have suggested that cannabis use might be associated with aberrant effort-based decision making. The most popular theory positing changes in motivation due to cannabis use is the amotivation syndrome hypothesis, which suggests that chronic cannabis use results in impaired executive functioning, arousal, and affective reactivity leading to reduced capacity for goal-directed behavior other than drug seeking. However, only one study has examined this among cannabis users, and the results suggested no difference between cannabis and non-cannabis users. Further, other studies suggest greater effort expenditure among the substance using groups compared to controls. The current study extends these findings by examining the relation between cannabis use and effort-related decision making in a sample of college students. Cannabis using (n = 25) and non-cannabis using (n = 22) students completed the Effort Expenditure for Rewards Task (EEfRT), in which participants choose between a ‘hard’ task that requires pressing a button 100 times with the nondominant little finger for a large sum of money (high effort/high reward) or an ‘easy’ task that requires pressing a button 30 times with the dominant index finger for a smaller sum of money (low effort/low reward). Results were then compared between the cannabis and non-cannabis using groups. On average, participants selected the hard trials 46% of the time (SD = 19%). Participants successfully completed the hard trials 74% of the time (SD 29%), while they completed the easy trials 97% of the time (SD = 6%). No participant selected only hard or easy trials during the duration of the task. Cannabis users (M=41.40, SD=3.55) completed significantly fewer trials compared to nonusers (M=43.64, SD=3.74). Further, Nonusers (M=26.82, SD=10.01) selected easy trials significantly more often compared to cannabis users (M=21.40, SD=8.34), and nonusers (M=99%, SD=2%) also successfully completed easy trials more often compared to cannabis users (M=95%, SD=7%). However, cannabis users and nonusers did not differ in the number of hard trials selected (Cannabis users M=16.82, SD=5.67; Nonusers M=16.82, SD=7.68) or the percentage of successfully completed hard trials out of the total number of hard trials (Cannabis users M=72%, SD=27%; Nonusers M=76%, SD =32%). Both the reward magnitude and probability of reward receipt predicted greater likelihood of selecting a hard trial.

Houston","doi":"10.26828/cannabis.2021.01.000.37","DOIUrl":"https://doi.org/10.26828/cannabis.2021.01.000.37","url":null,"abstract":"Impulsivity has been implicated as a factor in cannabis use and cannabis-related problems. However, impulsivity is a multi-faceted construct. Recent work in substance use has used the UPPS-P Impulsive Behavior Questionnaire (UPPS-P), which is designed to assess five facets of impulsivity. Research examining these facets of impulsivity and cannabis use characteristics is somewhat inconsistent, but generally has suggested that Sensation Seeking and Lack of Premeditation may be related to cannabis use and Negative Urgency may be associated with cannabis-related problems. In addition, a substantial literature exists suggesting that mindfulness, the ability to focus one’s attention on the present moment in a non-judgmental, non-reactive, and tolerant manner, is decreased in substance users. However, the literature specific to mindfulness and cannabis use characteristics is relatively inconsistent. Thus, the aim of the current study was to replicate and extend prior research on the associations between impulsivity, mindfulness, and cannabis use. A community sample of adults (N = 289, 137 female) completed an online survey that included the Short UPPS-P (SUPPS-P) impulsiveness questionnaire, Mindfulness Attention Awareness Scale (MAAS), and questions about cannabis use and cannabis-related problems. A logistic regression in the full sample revealed that SUPPS-P Lack of Premeditation and MAAS total scores, as well as alcohol consumption, were significant positive predictors of cannabis user status (i.e., use in the past 30 days). The Lack of Premeditation finding is consistent with prior studies, but the association between increased mindfulness and cannabis user status was unexpected. It’s possible that the mind set and physical setting in which cannabis is used has influence on the subjective experience, and thus, users may be seeking effects relevant for an overall sense of well-being similar to that seen in research on psychedelic drug use. In the subsample of cannabis users that reported use in the past 30 days (n = 87), no significant associations were revealed between impulsivity facets or mindfulness and cannabis use frequency. No impulsivity or mindfulness variables emerged as significant predictors of cannabis-related problems in users; although, consistent with prior studies, the association with SUPPS-P Negative Urgency approached significance. Alcohol-related problems were associated with cannabis-related problems as well. These findings extend the previous literature and have implications in identifying risk for problematic/disordered use as well as improving upon interventions and treatment approaches for problematic cannabis use.","PeriodicalId":383892,"journal":{"name":"Abstracts from the 2020 Virtual Scientific Meeting of the Research Society on Marijuana July 24th, 2020","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125641224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
