Newest firstThis study examined the prevalence and patterns of polydrug use among a national sample of civilians aged 12 years or older, with a focus on polydrug use involving opioids, assessing the influence of the first drug used on these behaviors. Using 2020 National Survey on Drug Use and Health (NSDUH) data, five mutually exclusive drug groups were identified in a hierarchical order: opioid use, stimulant or psychoactiv…
Sublingual (SL) drug delivery represents an important alternative route of analgesic administration, particularly in settings where rapid pain control is desired or oral and parenteral routes are limited. By enabling direct absorption through the oral mucosa, SL administration partially bypasses first-pass hepatic metabolism, potentially improving bioavailability and accelerating the onset of action for select med…
Comorbid substance use disorders (SUDs) are common but difficult to study due to the complex, interacting and overlapping mechanisms through which they affect brain networks. Many datasets collected to investigate a specific SUD include participants with comorbid SUDs. Although most studies treat comorbid SUDs as covariates of no interest, these covariates also contain untapped information. This is particularly re…
MOTIVATION: Opioid use disorder (OUD) often emerges following prescription opioid exposure and follows a dynamic clinical course characterized by onset, remission, and relapse. Large-scale cohorts linking electronic health records (EHR) with rich longitudinal survey data, such as the All of Us Research Program, enable computational modeling of stage-specific risk and provide an opportunity to connect predictive fa…
Background Opioid use disorder (OUD), particularly injection drug use (IDU), is on the rise and is associated with complications such as blood-borne infections, overdosing, and seizures, among others. Understanding factors distinguishing non-injecting opioid users (NIOU) and IDUs is essential for the development of effective prevention and management strategies. This study aimed to compare sociodemographic, clinic…
Background Marijuana use is rising in the United States, yet its impact on perioperative outcomes remains poorly understood, particularly in orthopaedic trauma where cessation is often not feasible. This study evaluates the risks associated with cannabis and nicotine use in patients undergoing fixation of upper extremity fractures. Methods We performed a retrospective analysis of adult trauma patients with upper e…
Polysubstance use disorders ( ≥ 2 substance use disorders (SUDs)) are associated with high morbidity and mortality. We analyzed data from 92,233 adult participants in the 2022-2023 US National Surveys on Drug Use and Health to estimate past-year prevalence of polysubstance use disorders and to examine their associations with age of substance use initiation. Multivariable logistic regression and Poisson regression…
ObjectiveIn this study, we evaluated the concordance between urine drug screening (UDS) and self-reported use in a pragmatic randomized clinical trial.MethodsOur data was drawn from OPTIMA, a 24-week pragmatic multicentric open-label randomized-controlled trial comparing flexible take-home dosing of buprenorphine/naloxone to the methadone standard model of care for treating prescription-type opioid use disorder. A…
Rationale The ongoing global opioid crisis underscores the need to better understand the neurobiological mechanisms underlying opioid use disorder (OUD). Stress is a key risk factor for developing and maintaining OUD. While animal models report that the endocannabinoid system (ECS) plays a modulatory role in stress response, alterations of ECS stress reactivity in individuals with OUD have yet to be studied. Objec…
Opioid use disorder (OUD) remains a major public health crisis, underscoring the urgent need for safer and more effective treatments. Cannabinoid CB2 receptor (CB2R) agonists show therapeutic promise for neuropsychiatric disorders and pain, with minimal psychoactive effects by themselves, but their potential in treating OUD is not well defined. Here, we report that MRI-2594, a novel, highly selective CB2R agonist,…
Substance use disorders (SUDs) remain a major public health concern and contribute substantially to compromised quality of life, mortality, and healthcare burden. In the United States alone, millions of individuals are affected by alcohol use disorder (AUD), tobacco use disorder (TUD), and opioid use disorder (OUD), with many cases complicated by co-existing anxiety and stress-related disorders. Piper methysticum…
Background Drug abuse causes substantial psychological and physical harm to individuals, highlighting the critical need for advanced diagnostic and treatment methodologies. Objective This study aimed to develop a highly accurate automatic detection system for substance abuse, specifically targeting Methamphetamine (Meth), Cannabis (Can), and Opioid (Op) users. Material and methods This descriptive study developed…
Background Cannabis use is increasing globally, with a parallel rise in Cannabis Use Disorder (CUD). Chronic pancreatitis (CP), a progressive inflammatory condition, is associated with acute pancreatitis (AP) flares and an elevated risk of pancreatic cancer (PC). Although cannabis is often used for pain management in CP, its impact on PC risk and AP flare frequency is unclear. Methods We conducted a retrospective…
Background and hypothesis Evidence suggests a complex interplay among childhood trauma (CT), substance use, and psychopathology in psychosis, yet the precise nature of these relationships remains unclear. Network analysis offers distinct advantages for examining these factors simultaneously, as it can capture multidirectional associations across multiple trauma subtypes, substances, and symptoms that conventional…
BACKGROUND: Persistent, multimodal cancer pain remains a challenge, particularly in long-term survivors facing treatment-related complications. The management of high-dose opioid dependence concurrent with chronic, multi-drug resistant (MDR) periprosthetic infection presents a critical unmet need. This case reports the potential use and sustained efficacy of medical cannabis monotherapy, highlighting an unexpected…
Background Two-thirds of adults in the United States (U.S.) find recreational and medical cannabis use acceptable. Evidence shows that cannabis use is an effective treatment for pain, and as a harm reducing therapeutic for Substance Use Disorder (SUD). In contrast to most SUD treatment models, some models allow illegal substance use as a harm reduction strategy, which is the case for the SUD treatment program exam…
Background Cannabinoids are increasingly discussed as adjuncts in addiction treatment, yet whether they improve clinically meaningful substance use disorder (SUD) outcomes beyond short-term symptom relief is unresolved. We determined whether cannabinoid exposure confers directional efficacy across opioid, alcohol, cocaine, tobacco, and methamphetamine use disorders, distinguishing symptomatic targets from sustaine…
Prescription opioid misuse is a significant public health concern among individuals with chronic pain. Treating severe pain often requires high doses of opioids, increasing the risk of developing an opioid use disorder. Cannabidiol (CBD) is a non-intoxicating component of cannabis that has shown therapeutic potential without abuse liability. This study investigated the effects of CBD on oxycodone self-administrati…
Background Substance use disorders (SUDs) remain a major source of preventable morbidity and mortality in the United States. This study described trends in the burden of SUDs from 1990 to 2019 by substance, sex, and age, and examined whether state-level policy environments and behavioral health budgets differed across states with the highest and lowest SUD-related disability-adjusted life years (DALYs). Methods We…
Purpose The global increase in the prevalence of substance use disorders (SUD) has resulted in higher mortality rates. While heroin use has decreased or stabilized, methamphetamine use is increasing, and the combined use of opioids and methamphetamine is becoming more common. FAAH is an enzyme that hydrolyzes endocannabinoid substances and plays a role in neurobehavioral processes. The aim of this study was to inv…
