‘It Helped to Calm Me’
BACKGROUND: Research on the benefits of cannabis use continues to expand, and those benefits may extend to parents and pregnant people. However, there are few studies that examine perspectives of pregnant and parenting individuals who use cannabis, and no studies with parents who are medical cannabis patients for treatment of qualifying conditions (e.g., chronic pain, anxiety). METHODS: We used a thematic content analysis approach to analyze 24 s…

Controlled Use of Cannabis Among Young Adults in Los Angeles Across Changes in Cannabis Policies
The availability of cannabis has increased due to expanding legalization of cannabis across the USA. Controlled use of cannabis - rules by cannabis users that limit use - is a significant but understudied area in the present policy environment, particularly among young adults. A prospective Los Angeles-based cohort aged 18-26 who used cannabis in the past 90 days was assessed during eight survey waves across 9 years. Four discrete waves were anal…
Role Strain Among Parents Who are Medical Cannabis Patients in Pennsylvania
As medical cannabis legalization expands in the United States, more parents and people of child-bearing age are becoming medical cannabis patients (MCP). This analysis uses the theory of role strain to explore how parents navigate being an MCP in Pennsylvania. Twenty four semi-structured qualitative interviews with parents from an ongoing registry study of MCP were analyzed using an a priori codebook and complemented by codes to capture emergent …
Cannabis Practices and Cannabinoid/Terpene Preferences in Medical Cannabis Patients Who Use Cannabis for Pain and Anxiety
Therapeutic potential of cannabinoids and terpenes in cannabis products is complicated by the possibility to alleviate pain yet exacerbate anxiety symptoms. Little is known about how cannabis practices, and preferences for cannabinoids and terpenes differ among medical cannabis patients who use cannabis to relieve pain, or anxiety, or both. A concurrent explanatory mixed-methods design was utilized. The quantitative analytical sample ( n = 1,060)…
Mental and Physical Health-Related Cannabis Motives Mediate the Relationship between Childhood Trauma and Problematic Cannabis Use over Time among Emerging Adult Cannabis Users
Background While growing evidence has identified mental and physical health-related cannabis use motives as significant mechanisms between childhood trauma and problematic cannabis use (PCU) for emerging adults (EA), there is a need to understand the longitudinal stability of these pathways and how they impact PCU as cannabis users age into later adulthood.Methods The current study extends an analysis examining the impact of childhood trauma (e.g…
Pre-Post Cannabis Legalization for Adult Use
Cannabis was legalized for adult use in California in 2016 for individuals 21 and older. Among 18-20-years-olds, who can possess cannabis legally as medical cannabis patients (MCP) but not as non-patient cannabis users (NPU), the impact of adult use legalization (AUL) on cannabis and other substance use is unknown. Two cohorts of 18-20-year-old cannabis users (MCP and NPU) were surveyed, one in 2014-15 ( n = 172 "pre-AUL") and another in 2019-20 …
Coping Motives Mediate the Association of Trauma History with Problematic Cannabis Use in Young Adult Medical Cannabis Patients and Non-Patient Cannabis Users
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 w…
Miscarriage and Abortion Among Women Attending Harm Reduction Services in Philadelphia
Background: Reproductive health research among women who use drugs has focused on pregnancy prevention and perinatal/neonatal outcomes, but there have been few investigations of miscarriage and abortion, including prevalence and associated factors. Methods: Using cross-sectional data from a sample of non-pregnant women receiving harm reduction services in Philadelphia in 2016–2017 we examined lifetime miscarriage and abortion (n = 187). Separatel…
A Qualitative Study of Self and Caregiver Perspectives on How Autistic Individuals Cope With Trauma
Autistic individuals use many strategies to cope with trauma, many of which are traditionally recognized as coping, but some of which may be less easily recognized given their overlap with autism-related behaviors. Findings highlight considerations for conceptualizing coping in autism, including factors influencing how individuals cope with trauma, and how aspects of autism may shape or overlap with coping behavior. Research building on these fin…
Pain Profiles among Young Adult Cannabis Users
Background Pain is a primary reason for medical cannabis use among young adults, however little is known about the patterns of pain in this group. This study identified pain profiles among young adult cannabis users and examined related antecedents and distal outcomes.Methods Past 30-day cannabis users aged 18–26, both medical cannabis patients and non-patients, were enrolled in Los Angeles in 2014–2015. A latent class analysis was used to identi…
Prevalence and Correlates of Syringe Disposal Box Use in a Philadelphia Neighborhood with High Levels of Public Drug Injection
Background: Philadelphia (Pennsylvania, USA) is facing an unprecedented public health crisis due to fentanyl use. To combat drug-related litter, the Philadelphia Department of Public Health installed 7 public syringe disposal boxes (SDB) in Kensington, the neighborhood most impacted by the opioid crisis and home to a syringe exchange. Methods: We used street- and business-intercepts to recruit residents (N=358) and business owners/staff (N=78) wh…
Overdose response among trained and untrained women with a history of illicit drug use
Little is known about differences in bystander behavior among people who use drugs, trained and untrained in opioid overdose prevention. We examined three types of recommended overdose response - a 911 call, rescue breathing/CPR, and naloxone administration-among Philadelphia-based, predominantly street-involved women with a history of illicit drug use. The study utilized a convergent mixed methods approach integrating data from 186 quantitative …

Changes in Medical Cannabis Patient Status before and after Cannabis Legalization in California
It is unknown how patterns of cannabis and other drug use changed among young adult cannabis users as they became, exited or stayed medical cannabis patients (MCPs) after California legalized cannabis for adult use in 2016. A cohort of 18–26 year-old cannabis users was recruited in Los Angeles in 2014–15 (64.8% male; 44.1% Hispanic/Latinx). Based on wave 1 (pre-legalization) and wave 4 (post-legalization) MCP status, four transition groups emerge…
Motivations for PrEP-Related Interpersonal Communication Among Women Who Inject Drugs
A qualitative egocentric social network approach was taken to explore motivations for pre-exposure prophylaxis (PrEP)-related communication between women who inject drugs and network members. Eligible participants were HIV-negative, 18 years or older, and participating in a PrEP demonstration project in Philadelphia, PA, USA. The study employed content analysis of in-depth interviews to identify themes related to contextual and relational factors…
Developmental trajectories of illicit drug use, prescription drug misuse and cannabis practices among young adult cannabis users in Los Angeles
Circumstances of overdose among street-involved, opioid-injecting women
I Gotta Go With Modern Technology, So I’m Gonna Give ’em the Narcan”
Fatal opioid overdoses can be prevented by opioid overdose prevention programs (OOPPs). The present study qualitatively examined the diffusion process of an OOPP among 30 persons who inject drugs (PWIDs) in an opioid-saturated community. Purposive sampling was used to recruit participants into three groups based on familiarity with the OOPP. Findings revealed that participants often adopted the OOPP, which was offered by a local harm reduction or…

Panhandlers or street beggars are a highly stigmatized collection of individuals. In addition to publicly displaying their homeless status, panhandlers suffer numerous other indignities while begging passersby for spare change. Despite these humiliations, many panhandlers enhance their self-regard and status by developing relationships with givers who become regular sources of support. These ongoing relationships are advanced by panhandlers who l…
Panhandling Repertoires and Routines for Overcoming the Nonperson Treatment
In this article, I present panhandling as a dynamic undertaking that requires conscious actions and purposeful modifications of self, performances, and emotions to gain the attention and interest of passersby. I show that describing and theorizing panhandling in terms of dramaturgical routines is useful in understanding the interactions and exchanges that constitute panhandling. In addition, repertoires rightly portray panhandlers as agents engag…

Patterns of Ketamine Use Among Young Injection Drug Users
Ketamine is a dissociative anesthetic that has emerged as an increasingly popular choice among young drug users. Recent research indicates the presence of hidden populations of young people who inject ketamine in New York and other U.S. cities. Applying an ethno-epidemiological approach, the authors recruited 40 young injection drug users (IDUs) (< 25 years old) in New York City to explore health risks associated with ketamine use. This analysis …
Multiple Drug Use and Polydrug Use Amongst Homeless Traveling Youth
Diverse forms of drug use are an emerging theme within research on young people and substance use. This manuscript, based on a three city study of health risks amongst young injection drug users, explores multiple drug use and polydrug use amongst a subset of homeless youth referred to as "travelers." In particular, we outline characteristics of homeless traveler youths and the various ways in which they practiced multiple drug use and polydrug u…
Towards an Explanation of Subjective Ketamine Experiences among Young Injection Drug Users
Ketamine is a dissociative anesthetic with powerful sedative and hallucinogenic properties. Despite the wide variability in reported subjective experiences, no study has attempted to describe the particular factors that shape these experiences. This manuscript is based upon a sample of 213 young injection drug users recruited in New York, New Orleans, and Los Angeles with histories of ketamine use. Qualitative interviews focused on specific ketam…
