Abstract The use of cannabinoids from hemp, which is classified as a cultivar of Cannabis sativa with up to 0.3% delta-9-tetrahydrocannabinol by USA federal definitions, is becoming increasingly popular in veterinary medicine. Owners frequently ask about their utility in a variety of conditions, including predominantly osteoarthritis, behavioral management, cancer, dermatitis and seizure disorders. Cannabinoid clinical utility, particularly cannabidiol (CBD) in dogs, is gradually emerging, while evidence for its use in cats remains limited. Several newer publications around the pharmacokinetics of CBD and cannabidiolic acid in cats show dramatic differences in bioavailability, elucidating that not all formulations are similar regarding serum or plasma concentrations. To date, although...

Abstract Cannabinoid hyperemesis syndrome (CHS) is a paradoxical condition seen in chronic cannabis users, marked by recurrent nausea, vomiting, and abdominal discomfort. Although more widely recognized in emergency medicine, CHS remains underdiagnosed in the perioperative setting, where its symptoms may be misattributed to common postoperative phenomena such as anesthetic effects, opioid-induced nausea, or surgical complications. This diagnostic gap can delay appropriate management and lead to unnecessary interventions. We report the case of a 40-year-old woman with a two-year history of daily cannabis use who underwent a laparoscopic hysterectomy, mid-urethral sling placement, and pelvic organ prolapse repair....

Abstract The marijuana is considered as widely used recreational illicit drug that has become popular among women of reproductive age. It is believed that the marijuana use may have negative impacts on the female fertility. However, the exact mechanisms of its reproductive toxicity remain unclear. The studies suggest that the exogenous cannabinoids may interfere with endocannabinoid system and disrupt hypothalamic-pituitary-ovary axis. Consequently, it impacts the female fertility by disruption of normal secretion of ovarian sex hormones and menstrual cycles. However, other studies have shown that medical marijuana is useful analgesic agent for pain management. But, given that the wide range of cannabinoids side effects...

Abstract Aims This study aimed to investigate the differences in psychotic symptomatology, dissociative symptoms, alexithymia, and aberrant salience among three groups: non-cannabis users (NU), natural cannabis users (NC), and synthetic cannabinoid users (SCs). The study also explored the patterns of alexithymia and its associations with other psychopathological dimensions in these populations. Methods A total of 108 participants experiencing First Episode Psychosis (FEP) were recruited during psychiatric crisis presentations to emergency rooms in Italy and categorized into three groups (NU, NC, SCs; n = 36 each). Participants were initially assessed 48–72 h after inpatient admission following clinical stabilization. Psychopathological assessments were conducted using the Positive and Negative Syndrome Scale (PANSS), Dissociative Experiences Scale (DES-II),...

Abstract Background: The gut–brain axis (GBA) is a complex bidirectional communication system that links the gastrointestinal tract and the central nervous system. Essential oils (EOs) have emerged as promising natural compounds capable of modulating this axis. Methods: A comprehensive analysis of the recent literature was conducted, focusing on studies investigating the effects of EOs on the GBA. Particular attention was given to the endocannabinoid system, the role of cannabis-derived EOs, and other plant-based EOs with potential neuroprotective and gut microbiota-modulating effects. Results: Among the EOs analyzed, cannabis essential oil (CEO) gained attention for its interaction with cannabinoid receptors (CBR1 and CBR2), modulating gut motility, immune responses,...

Abstract Introduction: With the changing legal landscape, the acceptance and availability of cannabis products have increased. Cannabis products are generally considered “natural” and relatively safe by consumers. However, growing empirical evidence from humans and other animals indicates that cannabis negatively affects human health. In contrast to the well-known teratogenic effects of alcohol and tobacco products, the safety of cannabis product use during pregnancy has not yet been established. The goal of this systematic review was to determine the patterns that exist in human and rodent literature on the effects of prenatal exposure to cannabis products and delta-9-tetrahydrocannabinol (THC) on birth outcomes. Methods: A systematic...

Abstract The escalating use and legalization of cannabis (marijuana) in the United States reflect shifting societal attitudes and growing awareness of its potential therapeutic benefits. Historically viewed as a harmful psychoactive substance, contemporary research has shown the intricate pharmacology of cannabis, with its diverse array of cannabinoids and their interactions with the endocannabinoid system. Among these cannabinoids, Δ9-tetrahydrocannabinol is the primary psychoactive component, characterized by its activation of cannabinoid receptors. The discovery of endocannabinoids, including anandamide and 2-arachidonoylglycerol, illuminated the body's innate cannabinoid signaling pathways and their involvement in several physiological processes. Endocannabinoids exert both positive...

Abstract The use of Cannabis sativa by humans dates back to the third millennium BC, and it has been utilized in many forms for multiple purposes, including production of fibre and rope, as food and medicine, and (perhaps most notably) for its psychoactive properties for recreational use. The discovery of Δ9-tetrahydrocannabinol (Δ9-THC) as the main psychoactive phytocannabinoid contained in cannabis by Gaoni and Mechoulam in 1964 (J Am Chem Soc 86, 1646–1647), was the first major step in cannabis research; since then the identification of the chemicals (phytocannabinoids) present in cannabis, the classification of the pharmacological targets of...

Abstract Cannabis has been used for recreation and medical purposes for more than a millennium across the world; however, its use’s consequences remain poorly understood. Although a growing number of surgical patients are regular cannabis consumers, little is known regarding the pharmacological interactions between cannabis and general anesthetics; consequently, there is not a solid consensus among anesthesiologists on the perioperative management of these patients. The existing evidence about the molecular mechanisms underlying pharmacological interactions between cannabinoids and anesthetic agents, both in animal models and in humans, shows divergent results. While some animal studies have demonstrated that phytocannabinoids (tetrahydrocannabinol [THC], cannabidiol [CBD], and cannabinol [CBN])...

Abstract An impact of legalization and decriminalization of marijuana is the gradual increase in the use of cannabis for recreational purposes, which poses a potential threat to society and healthcare systems worldwide. However, the discovery of receptor subtypes, endogenous endocannabinoids, and enzymes involved in synthesis and degradation, as well as pharmacological characterization of receptors, has led to exploration of the use of cannabis in multiple peripheral and central pathological conditions. The role of cannabis in the modulation of crucial events involving perturbed physiological functions and disease progression, including apoptosis, inflammation, oxidative stress, perturbed mitochondrial function, and the impaired immune system, indicates medicinal values. These...
