Industrial hemp (Cannabis sativa L.) is a plant matrix whose use is recently spreading for pharmaceutical and nutraceutical purposes. Detailed characterization of hemp composition is needed for future research that further exploits the beneficial effects of hemp compounds on human health. Among minor constituents, carotenoids and fat-soluble vitamins have largely been neglected to date despite carrying out several biological activities and regulatory functions. In the present paper, 22 target carotenoids and fat-soluble vitamins were analyzed in the inflorescences of seven Italian industrial hemp varieties cultivated outdoor. The analytes were extracted by cold saponification to avoid artifacts and analyzed by high-performance liquid chromatography coupled with Selected reaction monitoring mass spectrometry. Phytoene, phytofluene, and all-trans-β-carotene were the most abundant in all analyzed samples (31-55 µg g, 11.6-29 µg g, and 7.3-53 µg g, respectively). Besides the target analytes, liquid chromatography coupled with photodiode-array detection allowed us to tentatively identify several other carotenoids based on their retention behavior and UV-vis spectra with the support of theoretical rules and data in the literature. To the best of our knowledge, this is the first comprehensive characterization of carotenoids and fat-soluble vitamins in industrial hemp inflorescence.

The southwestern, central, and northeastern regions of China are the primary cultivation areas for industrial hemp. Microorganisms within the soil-root continuum play a crucial role in plant health. However, the mechanisms by which these microbial communities respond to environmental gradients remain unclear.

Objective: Cannabis retail dispensaries have proliferated in the United States in recent years, making it an important time for conducting research. Research is needed to learn more about consumer purchasing behaviors, including the impact of product marketing both inside and outside of retail spaces, and studies are needed to explore how both consumers and retail staff interpret the health benefits and potential risks associated with cannabis products within these environments. Current research on cannabis dispensaries often involves surveys or interviews with customers and dispensary staff outside of dispensary environments, but much can be learned through observational and experimental methods within dispensaries themselves.

Background: Australia has one of the highest rates of cannabis use globally, yet the concentration of Δ9-tetrahydrocannabinol (THC) of illicit street cannabis has not been formally assessed in over a decade. We aimed to comprehensively profile the concentration of THC, cannabidiol (CBD) and other cannabinoids in contemporary illicit street cannabis in regional Australia, assess variation over time, and examine how the amount of THC relates to consumer's perceived product strength.
Methods: Participants donated two 1-gram samples of cannabis at 3 different timepoints (i.

Introduction: Tobacco companies advertised cigarettes in popular media to increase social acceptability. Most research on e-cigarette product placement has been content analyses of music videos. We explored the motivations, activities, and results of product placement activities of the e-cigarette company Ploom and its successors, Pax Labs and Juul Labs, in music videos as well as film and television.

Cannabis is the most widely consumed illicit drug worldwide and its rapid expansion into medical and recreational markets has highlighted the need for effective analytical techniques. The analysis of major cannabinoids and their metabolites in different matrices has recently gained considerable attention in fields such as forensics, healthcare, environmental monitoring, and the cannabis food industry. However, the complexity of these matrices, ranging from biological samples to cannabis-infused products, raises significant challenges that require selective and effective extraction methods prior to chromatographic analysis.
