Abstract Aims To estimate the strength of association between psychiatric disorders and substance use disorders (SUD), and cannabis use and cannabis use disorder (CUD) during early pregnancy. Design Observational study. Setting Kaiser Permanente Northern California, USA. Participants 299 496 pregnancies from 227 555 individuals screened for cannabis use by self-report and a urine toxicology test at entrance to prenatal care in Kaiser Permanente Northern California during January 2011–December 2021 (excepting year 2020). The sample was 62.5% non-White, with a mean (standard deviation) age of 31.1 (5.5) years; 6.8% used cannabis; 0.2% had a CUD. Measurements Exposure variables included electronic...

Conventional pharmacotherapies for insomnia, initially comprising benzodiazepines and later the Z-drugs, often present significant adverse effects, including dependence and tolerance. Here we provide a brief review on cannabis therapy for insomnia and present a relevant case report. We first discuss the sleep stages and the main clinical aspects of insomnia. Next, we report the case of a 37 year-old patient who, after a grief situation, began to experience insomnia that was resistant to various conventional treatments, even with dosage adjustment. The...

Abstract Social factors significantly influence the initiation and progression of cannabis use and cannabis use disorder. Although cannabis is the most widely used drug globally, its social cognitive aspects and neural correlates have rarely been studied. To evaluate the findings to date and to guide future research, this systematic review assesses neuroimaging evidence on the associations between long-term cannabis use, social cognition, and emotion recognition. Findings from 8 studies on social cognition suggest an increased neural response to social influence and a decreased neural sensitivity to social exclusion, psychosocial stress, and social reward. However, these results should be interpreted with caution, and further replication...

Abstract Background The association between the age of cannabis use (CU) onset and substance use (SU) problems has been extensively studied, yet findings remain inconsistent. Aims This systematic review aimed to examine prospective studies on the association between age of CU onset and later SU problems, controlling for key individual, social, and SU-related risk factors. Methods PsycINFO, Web of Science and PubMed were searched for studies published between January 2000 and December 2024. Studies were included if they: 1) were prospective; 2) measured CU onset during adolescence; 3) measured CU or SU problems after CU onset, 4) examined whole plant or phytocannabinoids. Studies were...

Abstract Prenatal exposure to alcohol and tobacco has been associated with child regulatory abilities and problems, but less is known about the associations with cannabis exposure. This review seeks to address this gap primarily focusing on the effects of maternal cannabis use on the child. Thus, we investigate the association between pre- and postnatal cannabis exposure of the child and regulatory abilities and problems, as well as the underlying neurobiological mechanisms potentially mediating the associations. According to the PRISMA guidelines, a systematic literature review was performed based on a systematic literature search through Medline (PubMed), Web of Science and PsycInfo, including studies assessing children...

Abstract There is consistent evidence that brief interventions can be effective in preventing and reducing alcohol use, but support for their effects on illicit drug use is more limited. This meta-analysis expands prior research by testing whether brief drug interventions (BDIs) delivered in general medical settings reduce cannabis consumption and severity across post-intervention follow-up periods and explores potential heterogeneity in these effects. Findings from 17 randomized controlled trials were synthesized to compare short- and long-term cannabis use outcomes between intervention and control groups. Mixed effects meta-regression models were estimated to examine variability in effects across four intervention characteristics: booster session delivery, delivery setting, intervention...

Abstract Introduction: Taxane-induced peripheral neuropathy (TIPN) is experienced by most patients with breast cancer, and there is no efficacious treatment. In pre-clinical studies, co-administration of two constituents of cannabis, Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), synergistically reduces TIPN. Materials and Methods: The goal of this 8-week, double-blind, randomized pilot study, conducted from 2019 to 2021, was to test the feasibility and tolerability of oral cannabis (100 mg CBD: 5 mg THC, TID) relative to placebo on pain resulting from TIPN. Participants with painful TIPN completed daily questionnaires online about their pain, sleep, and medication use, and weekly questionnaires on...

It highlights the difficulties in getting a valid diagnosis because some patients do not admit its consumption, which may not be legalized, there are no commercial extracts and there are problems in cutaneous tests interpretation due to cross-reactivity with other related allergens. In addition to this, bronchial challenge is considered the confirmatory diagnosis, but it is complex to perform. This also occurs in diagnosis of occupational asthma, such as in baker’s asthma, in which we have investigated...

ABSTRACT Background People with HIV have a higher risk of developing non-AIDS-defining cancers in older age, leading to a significant population living with two conditions, HIV and cancer. There is an increasing interest in cannabis use for symptom management in people with chronic conditions; in 2023, the American Nurses Association officially recognised cannabis nursing as a specialty nursing practice focusing on the care of individuals seeking education/guidance in the therapeutic use of cannabis, supporting the urgency of its research. However, the scientific literature lacks a synthesised review in the focused populations. Aim To explore observational research...

Abstract Plant species of the genus Cannabis L. are predominantly recognized for their cannabinoids, which have garnered significant attention due to their bioactive properties. However, Cannabis also produces a diverse array of bioactive compounds with promising pharmacological potential that remain underexplored. This review focuses primarily on phytochemicals derived from Cannabis sativa L. subspecies, including both its drug-type and fiber-type varieties, which are the most widely cultivated and studied within the genus. Among these, nitrogen-containing compounds such as spermidine alkaloids exhibit neuroprotective and anti-aging properties, while hydroxycinnamic acids and hydroxycinnamic acid amides, including N-trans-caffeoyltyramine and N-trans-feruloyltyramine, have demonstrated notable antioxidant and anti-inflammatory activities. Additionally, Cannabis species are a valuable source of unique stilbenes,...
