Background: The recent interest among consumers in industrial hemp due to health and wellness benefits has led to several products from industrial hemp, including cannabidiol (CBD) oil. CBD oil extraction from hemp buds and flowers generates by-product biomass (), often posing disposal challenges and with little or no applications. We hypothesized that hemp flakes possess residual compounds with nutritional and health value that could be used to improve utilization.
Methods: Locally sourced hemp flakes were compared to three commercial hemp protein products. The nutritional composition (proximate analysis), heavy metals (Al, Cu, As, Pb, Co, Cd), and functional composition (phenolic and antioxidant properties-total phenolic compounds (TPC), total flavonoid compounds (TFC), ferric reducing antioxidant potential (FRAP), 1,1-diphenyl-1-picrylhydrazyl (DPPH), Trolox equivalent antioxidant capacity (TEAC)), (CBD, cannabiodiolic acid-CBDA, cannabichromene-CBC, cannabigerol-CBG, and cannabinol-CBN) contents were determined and compared.
Findings: Hemp flakes had a similar nutritional composition to commercial hemp protein products, with heavy metal levels within FDA allowed limits. The by-product had significantly higher CBDA levels than commercial products. Overall, hemp flakes had comparable nutrient composition and antioxidant capabilities. Based on the protein composition of hemp flakes (31.62 %) versus the highest commercial product (43 %), hemp flakes are an acceptable functional food ingredient.

Article Synopsis
- Biomass-derived carbon (BC) is a promising anode material for lithium-ion batteries due to its porous structure and ability to adsorb lithium, but it lacks a high specific surface area.
- A treatment involving NH and inorganic acid during urea decomposition enhances the surface area and nitrogen content of carbon derived from hemp, resulting in a product called nitrogen-rich graphite flake (NGF) with superior properties.
- NGF demonstrates significantly improved battery performance, with a capacity of 806.6 mAh/g and excellent rate capability, indicating strong commercial potential for nitrogen-rich activated carbon materials.
Local Anesthetic Efficacy in Marijuana Users and Nonusers: A Pilot Study.
Anesth Prog
December 2022
Department of Endodontics, University of Washington School of Dentistry.
Objective: Despite the common clinical impression that patients with a history of drug use are challenging to anesthetize with local anesthesia, literature on this clinical phenomenon is sparse. The objective of this pilot study was to assess if differences in local anesthetic efficacy for dental treatment exist between marijuana users and nonusers.
Methods: Subjects were healthy adult males and females who qualified as either chronic marijuana users or nonusers.
