Abstract
BACKGROUND There is evidence linking use of controlled substances with perpetration of interpersonal violence. While the United States constitution protects the right to own a firearm, federal law prohibits firearm purchase and possession by persons believed to be at high risk for violence, including those who use controlled substances unlawfully. METHODS We report here the results of a 13-year prospective observational study on the risk of violent crime associated with a history of criminal drug charges in a cohort of 79,678 legal purchasers of handguns in California in 2001. The main outcomes were post-purchase charges for any violent crime, violent Crime Index crimes (murder, rape, robbery, aggravated assault), and firearm-related violent crimes. The main exposure of interest was a history of pre-purchase charge(s) for drug-related offenses; we examined as a secondary exposure a history of marijuana-related charges. We estimated adjusted hazard ratios (aHR) with 95 % confidence intervals (CI) using Cox proportional hazards multiple events models. RESULTS We found that legal handgun purchasers in California with a history of drug-related charges, even those with marijuana charges only, had triple the risk of a post-purchase violent crime charge compared to purchasers with no criminal charges (drug charges only: aHR=2.9, 95 % CI 2.2-3.8; marijuana charges only: aHR=3.3, 95 % CI 1.8-6.0). In addition, a criminal history of drug charges only vs. no criminal history was associated with increased risk of one or more violent crime charges after the first post-purchase arrest event (aHR=1.6, 95 % CI 1.2-2.3). CONCLUSION It is incumbent on researchers and policy makers to understand the nature and causes of this risk in order to take effective steps towards mitigation.

Abstract
Federal restrictions have impacted funding for firearm-related research. We know little about the funding landscape for this research in the health sciences. A smaller proportion of articles reported funding in 2019 compared to 2000. Despite an increase in volume of publications, funding limitations still exist.
Federal funding for firearm-related research in the health sciences has incurred Congressional restrictions and executive actions. Little is known about the funding landscape for published scholarship in this field. This study’s aim was to characterize the number and sources of funding, including federal and non-federal sources, for firearm-related research articles published in health sciences journals. We performed a scoping review of original, empirical, peer-reviewed articles related to firearms published in health science journals and indexed in PubMed between January 2000 and December 2019, using the PRISMA extension for Scoping Review checklist. Four reviewers independently screened each article twice for inclusion. Included articles were reviewed again to identify funding sources. Articles were characterized as having explicitly declared funding, explicitly declared no funding, or no explicit funding declaration. Among articles with funding, we examined proportions by funding source. 812 articles met the inclusion criteria. 119 (14.7%) of the articles declared not having received any funding, and 240 (29.6%) had no funding declaration. 453 (55.8%) of the articles declared at least one source of funding. Of those, 221 (48.8%) reported at least one federal grant, and 232 (51.2%) reported at least one philanthropic grant. The number of published articles increased by 328.6% between 2000 and 2019. While the volume increased during the study period, the proportion of articles with funding was lower in 2019 (55.6%) than it was in 2000 (87.5%; proportion difference: 31.9%; 95% CI: 16.7%–47.2%). This study highlights the continued funding limitations in this field despite a growing volume of research.

Abstract
OBJECTIVES This study aims to examine whether periods of marijuana and other illicit drug dealing ("spells" of dealing) are associated with changes in young male offenders' gun carrying behavior. METHODS This paper uses 84 months of data from a sample of 479 serious juvenile male offenders who were assessed every six months for three years and then annually for four years. At each assessment, participants reported on engagement in illicit behaviors, including drug dealing and gun carrying, in each month since the prior interview. We used fixed effects models to assess within-individual changes in participants' gun carrying immediately before, during, and right after a dealing spell, while controlling for relevant time varying confounds (e.g., gang involvement, exposure to violence). Additionally, we tested moderation by type of drug sold. RESULTS There was a slight increase in gun carrying right before a drug dealing spell (OR = 1.3-1.4), then a more pronounced increase in gun carrying during the months of a drug dealing spell (OR = 8.0-12.8). Right after a dealing spell ends, youths' gun carrying dropped dramatically, but remained significantly elevated relative to their baseline levels (OR = 2.6-2.8). The association between drug dealing spells and increases in gun carrying was stronger when participants dealt hard drugs (e.g., cocaine, heroin) relative to marijuana. CONCLUSIONS These results suggest that designing and implementing programs to prevent the initiation of drug dealing and decrease involvement in drug dealing may help to substantially reduce illegal gun carrying and firearm violence among delinquent males.

Abstract
Objective: This study examines the effects of dynamic risk factors on handgun carrying from adolescence into young adulthood.Method: A nationally representative sample of 8,679 individuals (ages 12-26; 51.1% male; 58% White, 26.8% African American; 21.2% Hispanic ethnicity) from the National Longitudinal Survey of Youth (1997 cohort) interviewed at least three times across nine annual waves is used to estimate effects on handgun carrying. Key predictors include gang membership, selling and using drugs, violent crime, and arrest. Using mixed effects models, we focus on within-individual effects across three timeframes from ages 12 to 26: 1) predictors and handgun carrying measured concurrently, 2) predictors measured across one year and handgun carrying measured in the final month of the same year, and 3) predictors measured in the wave before handgun carrying. We also contrast estimates by sex and age.Results: All theoretically relevant predictors statistically significantly predict handgun carrying across the first two timeframes. However, none are statistically significant predictors of handgun carrying in the following year. Few significant sex and age differences emerge.Conclusions: Handgun carrying is an ephemeral behavior particularly during adolescence. The predictors of handgun carrying, which are grounded in gangs, drug use/sale, and crime involvement, appear to have short-term impacts that are consistent across age as well as across sex. Consequently, future work should focus on shorter-term changes in models and there is no evidence that intervention efforts must take fundamentally different approaches to reduce handgun use among males versus females or adolescents versus adults.

Abstract
This article examines whether weapon carrying influences the frequency and variety of violent, property, and drug delinquency adolescents commit through fixed-effects analyses of data from the Rochester Youth Development Study (RYDS). We conclude that weapon carrying contributes to violent, substance, and property delinquency, and delinquent behaviors learned during weapon carrying continue to affect substance and property delinquency long after carrying has ceased.

Abstract
The purpose of this study is to assess the association between gambling severity and exposure to guns among substance-using women recruited in the community. Data for these analyses come from the baseline phase of two community-based HIV prevention interventions conducted among alcohol and drug-using women in St. Louis, MO. Gun exposure was assessed using the Violence Exposure Questionnaire (VEQ), and DSM-IV pathological gambling (PG) symptoms and other psychiatric symptoms were assessed using the Computerized Diagnostic Interview Schedule; The Composite International Diagnostic Interview Substance Abuse Module assessed DSM-IV substance dependence, including cocaine dependence and alcohol dependence. Women in the study were predominantly African American (80%), mean age was 35.70 years ±8.8. Women exposed to guns were significantly more likely than women not exposed to guns to have gambled with all consequences: without meeting PG criteria (21% vs. 15%); to meet 1 to 4 PG criteria (22% vs. 12%), and to report 5 or more PG criteria (10% vs. 5%). These differences were significant at p < 0.0001. Based on the multivariate analysis, women who gambled without PG symptoms (OR = 1.77; 95% CI = 1.10-2.85) were nearly twice more likely to have exposure to guns than women who did not gamble. The risk for gun exposure increased with severity of gambling. Women who gambled and reported one to four PG criteria were twice as likely to have had an exposure to guns (OR 2.04; 95% CI = 1.45-3.06) and this risk increased to nearly threefold among women who met five or more criteria of PG (OR 2.65; 95% CI = 1.32-5.32). In addition, endorsing five or more criteria for major depressive disorder (OR 1.44; 95% CI = 1.00-2.06) and three or more criteria for antisocial personality adult criteria (OR 3.78; 95% CI = 2.03-7.02) were strong predictors for gun exposure among these women. The findings indicate that substance-using women with gambling behavior are at an enhanced risk to have exposure to guns.

Abstract
Gun-related violence is a public health concern. This study synthesizes findings on associations between substance use and gun-related behaviors. Searches through PubMed, Embase, and PsycINFO located 66 studies published in English between 1992 and 2014. Most studies found a significant bivariate association between substance use and increased odds of gun-related behaviors. However, their association after adjustment was mixed, which could be attributed to a number of factors such as variations in definitions of substance use and gun activity, study design, sample demographics, and the specific covariates considered. Fewer studies identified a significant association between substance use and gun access/possession than other gun activities. The significant association between nonsubstance covariates (e.g., demographic covariates and other behavioral risk factors) and gun-related behaviors might have moderated the association between substance use and gun activities. Particularly, the strength of association between substance use and gun activities tended to reduce appreciably or to become nonsignificant after adjustment for mental disorders. Some studies indicated a positive association between the frequency of substance use and the odds of engaging in gun-related behaviors. Overall, the results suggest a need to consider substance use in research and prevention programs for gun-related violence.

Abstract
We examine the prevalence and factors associated with lifetime gun-carrying among 858 urban out-of-treatment substance using women using data collected between 2000 and 2004 in a large Midwestern city. Instruments assessed gun ownership, carrying and access, psychopathology and personal lifestyle risk factors. Analyses were conducted using logistic regression. Illegal activities for income and lifetime violent victimization were the most significant predictors of gun carrying. The implications for practice and future research are discussed along with the study's limitations. The work was supported by grants from the National Institute on Drug Abuse and the National Institute on Alcohol Abuse and Alcoholism.

Abstract
Behavioral genetic research has consistently revealed that approximately one-half of the variance in antisocial behaviors is attributable to genetic factors. Even so, there is some reason to believe that different types of antisocial behaviors may have different developmental etiologies. The current study used this possibility as a springboard to examine the genetic and environmental influences on admission of drug-selling behaviors. Analysis of twin pairs drawn from the National Longitudinal Study of Adolescent Health revealed that 38% of the variance in a continuously coded drug-selling variable was accounted for by genetic factors and 69% of the variance in a dichotomously coded drug-selling variable was the result of genetic factors. The remaining variance for both measures was explained by nonshared environmental factors. The implications that these results have for drug research are discussed and avenues for future research are offered.
