Abstract This study explored the thermo-chemical properties of industrial hemp hurd with different provenances, maturity stages, and retting protocols. The findings were then compared to hemp hurd used in the fabrication of citric acid-bonded ultra-low-density hemp hurd particleboard. Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) were employed to document the variability of the hurd and comprehend the potential impact on biobased composite applications. The choice of cultivar, maturity stage, and processing modality significantly influenced the chemical composition, presence of functional groups, and thermal stability of the hurd. Py-GC/MS revealed substantial variations… More > Graphic Abstract

Abstract Cannabis is the most widely used drug in the Western societies particularly among adolescent and young adults. Epidemiological studies demonstrate that men use cannabis more frequently than women with higher risk in developing cannabis-related disorders. Although the direct adverse effects of cannabis on male reproductive functions have been studied both in humans and animal models, the possible long-term risks for the health of the users and their offspring are still an area of active research.
