Newest firstObjectives Opioid use has significantly increased in Germany in recent years. This study aimed to evaluate and compare the oral health, dental hygiene, self-perceived pain, and functional limitations of opioid-addicted patients with a healthy control group. Materials and methods 50 opioid-addicted patients (OAP) attending substitution treatment at the Centre for Addiction Medicine of the Department of Psychiatry a…
Open article record in new tab ↗Introduction We aimed to determine whether the trend in the rate of drug-induced hospitalisations and deaths changed during the first year of the COVID-19 pandemic in Australia. Methods Data comprised crude monthly rates (per 1,000,000 persons) of hospitalisations and deaths directly attributable to illicit drugs, prescription medicines, or medicines available without a prescription, nationally from 2011 to 2021.…
Open article record in new tab ↗Introduction Preterm delivery is an obstetric complication linked to an increased risk of postpartum depression (PPD), which often goes undiagnosed. Individuals with PPD may self-medicate to manage depressive symptoms. While postpartum substance use is well-documented, few studies have assessed whether preterm delivery is associated with new-onset substance use. A greater understanding of birth trauma as a factor…
Open article record in new tab ↗Cannabidiol (CBD) has emerged as a potential treatment option for various psychiatric disorders, including substance use disorders. This systematic review is aimed at reviewing the evidence regarding the safety and efficacy of CBD as a therapeutic option in opioid use disorder (OUD) treatment in clinical and preclinical studies. We searched MEDLINE, Embase, PsycINFO, Scopus, Web of Science, CDSR and CENTRAL up to…
Background To relieve acute and inflammatory pain, preparations of plant and animal origin have been used. The present work aimed to study the analgesic and anti-inflammatory effectiveness of a combined preparation based on viper venom and essential oil. Determining effective routes of exposure, optimal doses, the duration of action of the preparation, and possible mechanisms of their action were the areas of inte…
Background Drug use disorders (DUDs) pose a substantial global health burden, yet comprehensive analyses of their epidemiological trends, sociodemographic drivers, and cross-national disparities remain limited. Leveraging data from the Global Burden of Disease (GBD) 2021 study, we evaluated the global, regional, and national burden of DUDs from 1990 to 2021, focusing on opioids, cannabis, cocaine, amphetamines, an…
Open article record in new tab ↗Background Kratom (Mitragyna speciosa) use in the United States is becoming increasingly popular and its legal status varies widely from state to state. Multiple reports of adverse events associated with kratom use have ranged from liver injury, seizures, psychiatric disturbance, and rarely death. Methods This study investigated coroner autopsy reports from Kern County in California for the year 2020 which include…
Open article record in new tab ↗Objective Marijuana use is increasingly common among patients with chronic non-cancer pain (CNCP) and long-term opioid therapy (LTOT). We determined if lifetime recreational and medical marijuana use were associated with more frequent and higher dose prescription opioid use. Design Cross-sectional SUBJECTS: Eligible patients (n=1,037), who had a new period of prescription opioid use lasting 30-90 days, were recrui…
Open article record in new tab ↗Background Cannabis may be an alternative or adjunct to opioid therapy for chronic pain. However, there are limited data on patterns of opioid medication and medical cannabis use. The current study investigated the feasibility of using Ecological Momentary Assessment (EMA) to assess patterns of prescription opioids and medical cannabis among individuals experiencing chronic pain. Method The study included 133 part…
Open article record in new tab ↗Study design A retrospective cohort study. Purpose To examine the effect of cannabis use history on postoperative opioid utilization in patients undergoing one- to three-level lumbar fusion for degenerative spine disease. Overview of literature Strategies to minimize dosing and chronic opioid use are needed for spine surgery given their widespread prescription for postsurgical pain management. Methods In this data…
Open article record in new tab ↗Substance abuse is on the rise, and while many people may use illicit drugs mainly due to their rewarding effects, their societal impact can range from severe, as is the case for opioids, to promising, as is the case for psychedelics. Common with all these drugs' mechanisms of action are G protein-coupled receptors (GPCRs), which lie at the center of how these drugs mediate inebriation, lethality, and therapeutic…
Open article record in new tab ↗Magnolia grandiflora L. (Magnoliaceae) is a plant of considerable medicinal significance; its flowers and seeds have been used in various traditional remedies. Radioligand binding assays of n-hexane seeds extract showed displacement of radioligand for cannabinoid (CB1 and CB2) and opioid δ (delta), κ (kappa), and µ (mu) receptors. Bioactivity-guided fractionation afforded 4-O-methylhonokiol (1), magnolol (2), and…
BackgroundSubstance use disorders negatively affect global disease burden. Effective preventive interventions are available, but whether they provide value for money is unclear.AimsThis review looks at the cost-effectiveness evidence of preventive interventions for cannabis use, opioid misuse and illicit drug use.MethodLiterature search was undertaken in Medline, CINAHL, PsycINFO, EconLit through EBSCOhost and EMB…
Open article record in new tab ↗Machaeriols and machaeridiols are unique hexahydrodibenzopyran-type aralkyl phytocannabinoids isolated from Machaerium Pers. Earlier studies of machaeriol A (1) and B (2) did not show any affinity for cannabinoid receptor 1 (CB1 or CNR1), although they are structural analogs of psychoactive hexahydrocannabinol. This study comprehensively reports on the affinities of isolated Machaerium Pers. compounds, namely mach…
Background Opioids have been commonly used to treat chronic pain, but they are associated with significant morbidity and mortality. Cannabis has been advocated as an alternative; however, a growing number of patients are now using a combination of opioid and cannabis and the impact of this combination is not well-studied. Aim We characterized use of opioid and/or cannabis in patients with chronic pain; and compare…
Open article record in new tab ↗The orbitofrontal cortex (OFC) and piriform cortex (Pir) play a role in fentanyl relapse after food choice-induced voluntary abstinence, a procedure mimicking abstinence because of availability of alternative nondrug rewards. We used in situ hybridization and pharmacology to determine the role of OFC and Pir cannabinoid and dopamine receptors in fentanyl relapse. We trained male and female rats to self-administer…
Open article record in new tab ↗The placebo effect can be defined as the improvement of symptoms in a patient after the administration of an innocuous substance in a context that induces expectations regarding its effects. During recent years, it has been discovered that the placebo response not only has neurobiological functions on analgesia, but that it is also capable of generating effects on the immune and endocrine systems. The possible int…
Mu opioid receptors (MORs) are expressed in the dorsal striatum, a brain region that mediates goal-directed (via the dorsomedial striatum), and habitual (via the dorsolateral striatum, DLS) behaviors. Our previous work indicates that glutamate transmission is depressed when MORs are activated in the dorsal striatum, inducing MOR-mediated long-term synaptic depression (MOR-LTD) or short-term depression (MOR-STD), d…
Open article record in new tab ↗The endocannabinoid system plays a central role in the earliest stages of embryonic, postnatal and adolescent neurodevelopment. Aberrant activity of this system at key developmental phases has been shown to affect neural development. The aim of this review is to synthesise and analyse preclinical insights within rodent populations, focusing on the effects that perinatal (embryonic, gestational and early postnatal…
