Abstract
Cannabis use disorder (CUD) and frequency of use are highly related to social anxiety disorder (SAD). With updates to diagnostic criteria of psychiatric disorders and recent changes in cannabis laws, the present study sought to explore the relationships between cannabis use, CUD, and social anxiety in a large nationally representative sample of individuals with lifetime (N = 1255) and past-year SAD (N = 980). Notably, we found that at the symptom level, at least weekly cannabis use was significantly related to fear or avoidance of social situations interfering with relationships in both samples. Weekly + cannabis use and CUD were significantly associated with lifetime SAD symptom severity, but only weekly + cannabis use was related to SAD severity in the past-year sample. We also found that weekly + cannabis use but not CUD was related to greater odds of seeking treatment for SAD and suicide attempt history. Overall, these data provide an updated examination of cannabis use and SAD using DSM-5 criteria and a large nationally representative sample and also highlight the importance of weekly + cannabis use as a marker of severity and suicide risk in individuals with SAD.

Abstract
Background: Despite evidence of the contribution of childhood trauma to the development of problematic cannabis use, its mediating pathways are largely unknown. Given the link between cannabis motives with trauma and problematic cannabis use, motives of use may represent a construct through which trauma impacts problematic cannabis use. Methods: A sample of 339 medical cannabis patient and non-patient young adult users from the Los Angeles area were sampled at baseline and one year later. The current study examined the impact of childhood trauma on problematic use through a variety of cannabis use motives. Results: Controlling for age, socioeconomic status, perceived stress, and baseline problematic use, endorsing the use of cannabis to cope with distress at baseline uniquely mediated the associations between different childhood trauma types (e.g., physical abuse, neglect, sexual trauma) and problematic use one year later. Experience of any childhood trauma was positively associated with coping motives, whereas emotional and physical abuse were positively associated with pain motives, and sexual abuse was positively associated with sleep motives. Using cannabis for coping and increasing attention/focus were also positively associated with higher problematic use, whereas using cannabis for sleep was inversely associated with problematic use one year later. Conclusions: The motives of coping with distress and inattention may represent intermediate constructs through which trauma leads to later problematic cannabis use. Results highlight the need to clarify the pathways between health and non-health-oriented motives and cannabis use over time.

Abstract
Cannabis is often used to manage pain among persons who suffer from chronic pain. Yet, despite much literature suggesting cannabis use problems are associated with mental health problems, little work has examined mechanisms of this relationship among a chronic pain population. Chronic pain is also associated with emotion dysregulation. Individuals with chronic pain who experience cannabis use problems may have less capacity to regulate negative emotions, which could relate to greater anxiety, depression, and suicidal ideation. Thus, the current study explored whether emotion dysregulation explained, in part, the relation between cannabis use problems and anxiety, depression, and suicidal ideation among adults with chronic pain. Participants were 431 opioid-using adults with current moderate to severe chronic pain, 176 were current cannabis users, of which 30.20% reported cannabis use problems. Results indicated a significant indirect relationship between cannabis use problems and anxiety [95% CI (.03, .05)], depression [95% CI (.03, .06)], and suicidal ideation [95% CI (.01, .01)] via emotion dysregulation. Tests of specificity suggested potential for a bi-directional effect for suicidal ideation (p < .001). Initial findings suggest that emotion dysregulation may be an important mechanism in the relationship between cannabis use problems and mental health among adults with chronic pain.

Abstract
PURPOSE OF REVIEW Historically, anxiety disorders have not been considered as important determinants of suicide, but in the last years, many works have challenged this assumption. Here, we will review the available evidence on the relationship between suicide and anxiety disorders (e.g., obsessive-compulsive disorder, post-traumatic stress disorder, generalized anxiety disorder, panic disorder, and body dysmorphic disorder), with special emphasis on findings published in the last years. RECENT FINDINGS Overall, anxiety disorders increase the risk of suicide. Specifically, 16% of patients with social anxiety disorder reported suicidal ideation in the previous month, and 18% of them had a history of suicide attempts. Similarly, in patients with panic disorder, suicidal ideation prevalence ranged between 17 and 32%, and 33% of them had a history of suicide attempts. Generalized anxiety disorder (GAD) was the most frequent anxiety disorder in completed suicides (present in 3% of people who committed suicide) and also subthreshold GAD was clearly linked to suicide ideation. Post-traumatic stress disorder was positively associated with suicidal ideation, and in patients with obsessive-compulsive disorder, suicide ideation rates ranged from 10 to 53% and suicide attempts from 1 to 46%. Body dysmorphic disorders presented a suicide ideation prevalence of about 80%. Suicide risk is increased in subjects with anxiety disorder. This risk is higher in the presence of comorbidities, but it is not clear whether it is independent from such comorbidities in some disorders.

Abstract
Cannabis use is a major public health concern, and identification of factors that increase risk of negative consequences of cannabis use may aid in the prevention and treatment of such disorders. Social anxiety has been shown to be robustly linked to negative consequences of cannabis use and cannabis use disorder. However, mechanisms that underlie these co-occurring conditions are not well understood. Socially anxious individuals engage in post-event processing (PEP; i.e., reviewing past social events in great detail), which tends to increase their negative affectivity. Given that negative affectivity can increase cannabis craving, PEP may place socially anxious individuals at risk for cannabis use. The current study set out to test this hypothesis using a web-based experimental design. Participants (N = 191) were randomized to complete one of three tasks, a negative PEP induction task, positive PEP induction task, and a neutral control task. Participants completed measures of cannabis use at baseline and one week after the task. Among participants engaging in negative PEP, social anxiety was related to increase in cannabis use quantity following the task relative to the other conditions. Negative PEP may be an important therapeutic target for socially anxious cannabis users.

Abstract
Cannabis use disorder (CUD) co-occurs with anxiety disorders at high rates. Little is known about the mechanisms linking CUD and anxiety disorders. One theoretically-driven perspective is that individuals with anxiety disorders may be more apt to use FSBs (i.e., behaviors that may be effective in decreasing anxiety in the short-term, but can maintain and even exacerbate anxiety in the long-term), which can perpetuate cannabis use despite cannabis-related problems. The present study tested whether FSB use explained the relation of anxiety symptom severity with cannabis quantity and related problems among 77 adults with CUD and comorbid anxiety disorders seeking outpatient CUD treatment. Results indicated that FSB frequency was significantly related to anxiety symptom severity and cannabis problem severity, but not cannabis quantity. Anxiety symptom severity was indirectly (via FSB frequency) related to cannabis problem severity, but not to cannabis quantity. These novel findings suggest that more frequent use of FSBs may play an important role in cannabis problem severity among individuals with CUD and anxiety disorders.

Abstract
OBJECTIVES Cannabis has been legalized for medical use in almost half of the states in the U.S. Although laws in these states make the distinction between medical and recreational use of cannabis, the prevalence of people using medical cannabis and how distinct this group is from individuals using cannabis recreationally is unknown at a national level. METHODS Data came from the 2013 National Survey on Drug Use and Health (NSDUH). All adults endorsing past year cannabis use who reported living in a state that had legalized medical cannabis were divided into recreational cannabis use only and medical cannabis use. Demographic and clinical characteristics were compared across these two groups. RESULTS 17% of adults who used cannabis in the past year used cannabis medically. There were no significant differences between those who used medically versus recreationally in race, education, past year depression and prevalence of cannabis use disorders. In adjusted analyses, those with medical cannabis use were more likely to have poorer health and lower levels of alcohol use disorders and non-cannabis drug use. A third of those who reported medical cannabis use endorsed daily cannabis use compared to 11% in those who reported recreational use exclusively. CONCLUSIONS Adults who use medical and recreational cannabis shared some characteristics, but those who used medical cannabis had higher prevalence of poor health and daily cannabis use. As more states legalize cannabis for medical use, it is important to better understand similarities and differences between people who use cannabis medically and recreationally.

Abstract
Given increasing marijuana use and abuse among young adults in the United States and the associated physical and mental health consequences, it is important to improve our understanding of factors that may contribute to problematic marijuana use. A convergence of theory and research underscores the relevance of particular marijuana use motives generally, and coping-related motives specifically, in enhancing risk for marijuana use problems. Distress tolerance is a transdiagnostic emotion vulnerability factor that may relate to coping-related motives for marijuana use. The current study was designed to further explore this relationship within a treatment-seeking sample of young adults (Mage=24.40; SD=2.06 years). Results were consistent with hypotheses, suggesting distress tolerance is related to coping motives for marijuana use within this treatment-seeking sample, even after accounting for a number of theoretically relevant covariates. Theoretical and applied implications of distress tolerance as it relates to coping motives for marijuana use as treatment targets are discussed.

Abstract
Social anxiety disorder appears to be a risk factor for cannabis-related problems. Although it is presumed that increases in cannabis craving during elevated social anxiety reflect an intent to cope with greater negative affectivity, it is unclear whether increases in physiological arousal during social stress are related to cannabis craving, especially among those with social anxiety disorder. Similarly, no studies have assessed motivational reasons for cannabis use during elevated social stress. Thus, the current study tested whether increases in state social anxiety (measured subjectively and via physiological arousal) were related to greater cannabis craving among 126 current cannabis users (88.9% with cannabis use disorder, 31.7% with social anxiety disorder, 54.0% non-Hispanic Caucasian) randomly assigned to either a social interaction or reading task. As predicted, cannabis users in the social interaction condition reported greater cannabis craving than those in the reading condition. This effect was particularly evident among those with social anxiety disorder. Although physiological arousal did not moderate the relationship between condition and craving, coping motives were the most common reasons cited for wanting to use cannabis and were reported more among those in the social interaction task. These experimental results uniquely add to a growing literature suggesting the importance of elevated state social anxiety (especially among those with social anxiety disorder) in cannabis use vulnerability processes.

Abstract
Research in community and clinical samples has documented elevated rates of cannabis use and cannabis use disorders (CUDs) among individuals with trauma exposure and posttraumatic stress disorder (PTSD). However, there is a lack of research investigating relations between, and correlates of, trauma and cannabis phenotypes in epidemiologic samples. The current study examined associations between trauma (i.e., lifetime trauma exposure and PTSD) and cannabis phenotypes (i.e., lifetime cannabis use and CUD) in a nationally representative sample. Participants were individuals who participated in Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (n = 34,396; 52.4% women; age, M = 48.0 years, SD = 16.9). Lifetime DSM-IV Criterion A trauma exposure was significantly associated with lifetime cannabis use (OR = 1.215) but was only marginally associated with CUD (OR = 0.997). Within the trauma-exposed sample, lifetime PTSD showed a significant association with CUD (OR = 1.217) but was only marginally associated with lifetime cannabis use (OR = 0.992). Partially consistent with hypotheses, lifetime trauma was associated with greater odds of lifetime cannabis use, whereas PTSD was associated with greater odds of CUD. Longitudinal research investigating patterns of onset of these events/disorders is needed.

Abstract
OBJECTIVE Socially anxious cannabis users are especially vulnerable to cannabis-related impairment, yet mechanisms underlying this vulnerability remain unclear. Socially anxious persons may use cannabis despite related problems if they believe such problems are common, and thus socially acceptable. Yet no known studies have examined the impact of beliefs regarding others' cannabis-related problems on one's own use-related problems. METHOD This study investigated the impact of beliefs about a close friend's experience with cannabis-related problems on the relationship between social anxiety and cannabis-related problems. The sample consisted of 158 (75% female) current (past-month) cannabis-using undergraduates. RESULTS Believing one's friend experienced more cannabis problems was related to experiencing more cannabis-related problems oneself. In fact, perceived friend's problems accounted for 40% of the unique variance in one's own cannabis problems. Descriptive norms (others' use) and injunctive norms (others' approval of risky use) were unrelated to the number of one's own problems. Social anxiety was related to experiencing more cannabis problems. This relation was moderated by perceived friend's problems such that greater social anxiety was related to more cannabis-related problems among participants who believed their friend experienced more cannabis-related problems. This was not the case among participants who believed their friend experienced fewer problems. CONCLUSIONS Normative beliefs regarding a close friend's cannabis problems were robustly and uniquely related to experiencing more cannabis-related impairment. Beliefs regarding friends' experience with cannabis-related problems may play an especially important role in the experience of cannabis-related problems among socially anxious users.

Abstract
BACKGROUND The aim of the current study was to investigate the association between anxiety and cannabis use/cannabis use disorders in the general population. METHODS A total of N = 267 studies were identified from a systematic literature search (any time- March 2013) of Medline and PsycInfo databases, and a hand search. The results of 31 studies (with prospective cohort or cross-sectional designs using non-institutionalised cases) were analysed using a random-effects meta-analysis with the inverse variance weights. Lifetime or past 12-month cannabis use, anxiety symptoms, and cannabis use disorders (CUD; dependence and/or abuse/harmful use) were classified according to DSM/ICD criteria or scores on standardised scales. RESULTS There was a small positive association between anxiety and either cannabis use (OR = 1.24, 95% CI: 1.06-1.45, p = .006; N = 15 studies) or CUD (OR = 1.68, 95% CI: 1.23-2.31, p = .001; N = 13 studies), and between comorbid anxiety + depression and cannabis use (OR = 1.68, 95% CI: 1.17-2.40, p = .004; N = 5 studies). The positive associations between anxiety and cannabis use (or CUD) were present in subgroups of studies with ORs adjusted for possible confounders (substance use, psychiatric illness, demographics) and in studies with clinical diagnoses of anxiety. Cannabis use at baseline was significantly associated with anxiety at follow-up in N = 5 studies adjusted for confounders (OR = 1.28, 95% CI: 1.06-1.54, p = .01). The opposite relationship was investigated in only one study. There was little evidence for publication bias. CONCLUSION Anxiety is positively associated with cannabis use or CUD in cohorts drawn from some 112,000 non-institutionalised members of the general population of 10 countries.

Abstract
OBJECTIVE Individuals with greater social anxiety are particularly vulnerable to cannabis-related impairment. Descriptive norms (beliefs about others' use) and injunctive norms (beliefs regarding others' approval of risky use) may be particularly relevant to cannabis-related behaviors among socially anxious persons if they use cannabis for fear of evaluation for deviating from what they believe to be normative behaviors. Yet, little research has examined the impact of these social norms on the relationships between social anxiety and cannabis use behaviors. METHOD The current study investigated whether the relationships of social anxiety to cannabis use and use-related problems varied as a function of social norms. The sample comprised 230 (63.0% female) current cannabis-using undergraduates. RESULTS Injunctive norms (regarding parents, not friends) moderated the relationship between social anxiety and cannabis-related problem severity. Post hoc probing indicated that among participants with higher (but not lower) social anxiety, those with greater norm endorsement reported the most severe impairment. Injunctive norms (parents) also moderated the relationship between social anxiety and cannabis use frequency such that those with higher social anxiety and lower norm endorsement used cannabis less frequently. Descriptive norms did not moderate the relationship between social anxiety and cannabis use frequency. CONCLUSIONS Socially anxious cannabis users appear to be especially influenced by beliefs regarding parents' approval of risky cannabis use. Results underscore the importance of considering reference groups and the specific types of norms in understanding factors related to cannabis use behaviors among this vulnerable population.

Abstract
Social anxiety is robustly associated with cannabis-related problems. This relation appears to be largely explained by coping-oriented motives for cannabis use. Yet, factors associated with coping motives among socially anxious individuals have yet to be identified. The current study tested whether experiential avoidance (i.e., unwillingness to experience distressing internal states) and its subfacets mediated the relation between social anxiety and coping motives for cannabis use. The sample consisted of current (past-month) cannabis-using adults (n = 103). Results indicated that social anxiety was robustly related to experiential avoidance, which was robustly related to coping motives. Follow-up analyses indicated that behavioral avoidance was the only experiential avoidance subtype to be related to both social anxiety and coping motives after controlling for theoretically relevant variables. Experiential avoidance (globally) and behavioral avoidance (specifically) mediated the relation between social anxiety and coping motives. Together, the results suggest experiential avoidance (especially behavioral avoidance) may play an important role in cannabis use behaviors, particularly among socially anxious users.
