Abstract Substantial preclinical evidence demonstrates the antiproliferative, cytotoxic, and antimetastatic properties of plant-derived cannabinoids (phytocannabinoids) such as cannabidiol and tetrahydrocannabinol. The cumulative body of research into the intracellular mechanisms and phenotypic effects of these compounds supports a logical, judicious progression to large-scale phase II/III clinical trials in certain cancer types to truly assess the efficacy of phytocannabinoids as anticancer agents.

Abstract Cannabis and cannabis-derived products are increasingly used for recreational and medical purposes including anxiety and epilepsy and are often concurrently used with other types of conventional medications. The concomitant use of cannabis with other therapeutic drugs has been shown to increase the likelihood of deleterious drug-drug interactions. Oxazepam is a well-known benzodiazepine used in clinical practice as an anxiolytic, sedative, and anticonvulsant agent. Oxazepam is a racemic mixture of the S-and R-enantiomers and is primarily metabolized via glucuronidation in an enantiomeric-specific manner, where S-oxazepam is mainly glucuronidated by UDP-glucuronosyltransferase (UGT) 2B15 and R-oxazepam is glucuronidated...

Abstract Cannabis sativa has chemically active compounds called cannabinoids, where Δ9- tetrahydrocannabinol (THC) and Cannabidiol (CBD) are the major ones responsible for the various pharmacological effects. The endocannabinoid system is an endogenous system considered a unique and widespread homeostatic physiological regulator. It is made up of type 1 (CB1) and type 2 (CB2) cannabinoid receptors. CBD, in turn, has a low affinity for CB1 and CB2 receptors, and regulates the effects arising from THC as a CB1 partial agonist, which are tachycardia, anxiety, and sedation. It also acts as a CB2 inverse agonist, resulting in anti-inflammatory effects. Furthermore, its anticonvulsant, neuroprotective, antipsychotic, antiemetic, anxiolytic,...

Abstract Background Neuropathic pain and other pain disorders have received attention as potential indications for use of cannabis-based medicines or medical cannabis (CBM/MC). Evidence regarding the efficacy and safety of CBM/MC for pain disorders is, however, insufficient. Denmark introduced a pilot programme of medical cannabis in January 2018. We aimed to evaluate efficacy, safety, and non-specific effects of CBM/MC used under the pilot programme compared with controls. Methods We conducted a nationwide register-based cohort study in Denmark, identifying all individuals redeeming at least one prescription for CBM/MC for either neuropathic pain (n = 1817) or other and unspecified...

Recent findings Cannabis products have continued to become more potent, particularly in regard to delta-9- tetrahydrocannabinol (THC) concentration. Additionally, the use of cannabis has continued to become more accepted with less legal restrictions. The reported use of cannabis for relief of symptoms in sleep disorders appears to be increasing, however the specific effects of cannabinoids on sleep varies with cannabinoid type and concentration. Some evidence supports claims of efficacy of cannabinoids in sleep disorders such as insomnia, while...

Abstract Inflammation often develops from acute, chronic, or auto-inflammatory disorders that can lead to compromised organ function. Cannabis (Cannabis sativa) has been used to treat inflammation for millennia, but its use in modern medicine is hampered by a lack of scientific knowledge. Previous studies report that cannabis extracts and inflorescence inhibit inflammatory responses in vitro and in pre-clinical and clinical trials. The endocannabinoid system (ECS) is a modulator of immune system activity, and dysregulation of this system is involved in various chronic inflammations. This system includes cannabinoid receptor types 1 and 2 (CB1 and CB2), arachidonic acid-derived endocannabinoids, and enzymes involved in endocannabinoid metabolism. Cannabis produces...

Abstract Background Cannabis products, including the cannabinoids CBD and THC, are rising in popularity and increasingly used for medical purposes. While there is some evidence that cannabinoids improve cancer-associated symptoms, understanding regarding appropriate use remains incomplete. Purpose To describe patient experiences with medical cannabis with focus on use contexts and patients’ reported benefits and harms. Methods A standardized intake form was implemented in a dedicated medical cannabis clinic at an NCI-designated cancer center; data from this form was abstracted for all initial visits from October 2019 to October 2020. We report descriptive statistics, chi-square analysis, and multivariate logistic regression. Results Among 163 unique new...

Abstract Substances from the Cannabis sativa species, especially cannabidiol (CBD) and Delta-9-tetrahydrocannabinol (Δ9-THC), have attracted medical attention in recent years. The actions of these two main cannabinoids modulate the cholinergic nervous system (CholNS) involving development, synaptic plasticity, and response to endogenous and environmental damage, as a characteristic of many neurodegenerative diseases. The dynamics of these diseases are mediated by specific neurotransmitters, such as the GABAergic nervous system (GNS) and the CholNS. The nematode Caenorhabditis elegans is an important experimental model, which has different neurotransmitter systems that coordinate its behavior and has a transgene strain that encodes the human β-amyloid 1–42 peptide in body wall muscle, one of the...

Abstract Due to differences in potency, efficacy, and affinity for CB1 receptors, similarities and differences in psychoactive effect profiles of natural cannabis and synthetic cannabinoids (SCs) cannot reliably be derived from equipotent dose comparisons. Instead, the current study proposes to compare the intrinsic psychoactive effects of natural cannabis (THC) and an SC, JWH-018, at psychotropic dose equivalence. Participants from two placebo-controlled studies were matched for their levels of subjective high to compare neurocognitive and psychotomimetic effects of THC and JWH-018. At equal subjective intoxication levels, both drugs impaired psychomotor, divided attention, and impulse control, with no significant difference between the two drugs. Both drugs...

Introduction Cannabis remains the most commonly used drug of abuse worldwide and the legalization in several states caused a drastic change in the variety of products available on the market. Over the past few years, several studies reported that the average concentration of Δ9-tetrahydrocannabinol (THC) drastically increased as well as the availability of products containing different combinations of THC and other cannabinoids, mainly cannabidiol (CBD). However, little is known about the acute effects of THC and/or CBD on the lipidome and more specifically the endocannabinoid system. The aim of the present study...
