Over the last two decades, the role played by phytocannabinoids and endocannabinoids in medicine has gained increasing interest in the scientific community. Upon identification of the plant compound Δ(9)-tetrahydrocannabinol (THC) and of the endogenous substance anandamide (AEA), different methodological approaches and innovative techniques have been developed, in order to evaluate the content of these molecules in various human matrices. In this review, we discuss the analytical methods that are currently used for the identification of phytocannabinoids and endocannabinoids, and we summarize the benefits and limitations of these procedures. Moreover, we provide an overview of the main biological matrices that have been analyzed to date for qualitative detection and quantitative determination of these compounds.

With legalisation of cannabis for both medicinal and recreational use expanding to more world nations, grasping its effects on the human body is vital. The microbiome is critical to human health and disease, and accumulating data suggests that it is influenced by a variety of external variables, including marijuana/cannabis and cannabinoids. We therefore conducted a comprehensive assessment of the literature to analyse cannabis and cannabinoid effects on the human microbiota.

Recent advancements have highlighted the potential of cannabis and its phytocannabinoids (pCBs) in skin health applications. These compounds, through their interaction with the endocannabinoid system (ECS), show promise for skin health products. Their ability to regulate inflammation, oxidative stress and cell proliferation makes them useful in addressing skin problems such as inflammation, scarring, healing, acne and aging, positioning them as valuable tools for innovative skincare solutions.

Article Synopsis
- FABP7 is a protein found in the brain that may help transport cannabinoids like THC, but its role in the endocannabinoid system is not fully understood.
- In a study using mice lacking FABP7, researchers measured THC and its metabolite 11-OH-THC levels after THC inhalation, finding that females with FABP7 deletion had lower levels of 11-OH-THC compared to those with the protein.
- The study also revealed that FABP7 influences endocannabinoid levels, showing females with FABP7 deletion had decreased levels of anandamide and increased levels of 2-AG, indicating a sex-specific role in THC metabolism and endocannabinoid regulation.

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.
