Abstract Background Cannabis use is a well-established environmental risk factor for psychosis and auditory hallucinations, yet the neurobiological mechanisms underlying this association remain incompletely understood. Neuroimaging studies of psychotic disorders have consistently implicated structural abnormalities within auditory and temporoparietal cortical networks involved in speech...

Abstract Background Chronic pain is one of the most common reasons for medicinal cannabis use, yet the neural mechanisms underlying cannabis-related modulation of pain remain poorly understood. Both pain and cannabis use independently alter functional connectivity within the brain’s default mode network (DMN) that modulate interoception and self-referential aspects of pain processing. The goal...

Abstract Background Cannabis is one of the most widely used psychoactive substances worldwide. Δ 9 -tetrahydrocannabinol (Δ 9 -THC) is the main contributor to cannabis-induced effects such as euphoria, anxiety, and psychotomimetic effects, and is metabolized by several hepatic enzymes, including CYP3A4. There are interindividual differences in how cannabis affects users, which have substantial...

Marijuana is the most commonly used illicit drug in the United States and its use is rising. Nonetheless, scientific efforts to clarify the risk for addiction and other harm associated with marijuana use have been lacking. Maladaptive decision-making is a cardinal feature of addiction that is likely to emerge in heavy users. In particular, distorted subjective reward valuation related to...

ABSTRACT Public perception of cannabis as relatively harmless, alongside claimed medical benefits, have led to moves towards its legalization. Yet, long-term consequences of cannabis dependence, and whether they differ qualitatively from other drugs, are still poorly understood. A key feature of addictive drugs is that chronic use leads to adaptations in reward processing, blunting responsivity...

Background. The global increase in lenient cannabis policy has been paralleled by reduced harm perception, which has been associated with cannabis use initiation and persistent use. However, it is unclear how cultural attitudes towards cannabis use might affect the brain processes underlying cannabis use. Methods. Resting state functional connectivity (RSFC) within and between the executive...

Abstract Importance Rates of prenatal cannabis exposure (PCE) are rising with increasingly permissive legislation regarding cannabis use, which may be a risk factor for psychosis. Disrupted reward-related neural circuitry may underlie this relationship. Objective To elucidate neural mechanisms involved in the association between PCE and youth-onset psychotic-like experiences by probing...

Background: This paper highlights the formulation of a solid THC-loaded ingestible prepared from pure THC distillate. A THC ethanol-assisted cannabinoid nanoemulsion (EACNE) was created without the need for specialized emulsification equipment such as a high-pressure homogenizer or a microfluidizer. Stress-testing was performed on the EACNE to evaluate its chemical and colloidal stability under...

Abstract Rationale Cannabis is the most widely used illicit substance in the United States, and its use is increasing with the recent push for legalization and decriminalization, as well as the growing use for medicinal purposes. While cannabis can have positive effects in some individuals, there are potential negative consequences including dependence, psychosis, and cognitive impairments. The...

Abstract The legalization of cannabis in several states across the US has increased the need to better understand its effects on the body, brain, and behavior, particularly in different populations. Rodent models are particularly valuable in this respect because they provide precise control over external variables. Previous rodent studies have found age and sex differences in response to...
