The article reports that in 2015, the American Academy of Pediatrics (AAP) updated its 2004 policy statement, "The impact of marijuana policies in youth." The recommendations which the AAP made in its 2015 policy statement include those relating to its positions on marijuana use and decriminalization, the development of pharmaceutical cannabinoids, and research on the benefits and risks of marijuana. An interview with Dr. Seth Ammerman, lead author of the 2015 policy statement, is also offered.

The article reports that Miriam A. Schizer, instructor of Pediatrics at Harvard Medical School, spoke on what pediatricians need to know when counselling teenagers and families about marijuana, during the 2015 American Academy of Pediatrics (AAP) National Conference and Exhibition in Washington, DC. Topics of Schizer's presentation are mentioned, including common names and ways of ingesting marijuana, the psychological effects of marijuana intoxication, and the harmful effects of marijuana use.

As the legalization of medicinal cannabis continues to sweep across the United States, an urgent need has developed for fast, accurate, and efficient analytical testing. In addition to testing for contaminants and potency, there is also interest in the determination of terpene identity and concentration levels present in different strains of cannabis. Terpenes have been shown to have therapeutic uses for treatment of different medical conditions ranging from cancer and inflammation to anxiety and sleeplessness. It is believed that the combination of terpenes and cannabinoids in cannabis produce a synergistic effect with regards to medical benefits. The traditional testing method for terpenes in plant materials involves a solvent-based extraction followed by gas chromatography (GC) analysis. In this work, headspace solid- phase microextraction (HS-SPME) was used to identify and quantify terpene content in cannabis. The HS-SPME method offered several advantages compared to solvent extraction in that it provided a cleaner analysis, free of interferences from coextracted matrix, and was nondestructive to the sample. A cannabis sample of unknown origin was first analyzed qualitatively by HS-SPME and GC-mass spectrometry (MS). Spectral library matching and retention indices were used to identify 42 terpenes. Quantitative analysis was then performed for several selected terpenes using spiked samples. Method accuracy was >90%, with reproducibility of <5% relative standard deviation (RSD) for analysis of spiked replicates. The HS-SPME results were then compared to an analysis using a conventional solvent extraction method, and the two approaches were found to produce comparable results. [ABSTRACT FROM AUTHOR]

This study focuses on an inductively coupled plasma-mass spectrometry (ICP-MS) sample preparation procedure and analytical methodology optimized for both toxic and nutritional elements in dried hops, a surrogate for the cannabis family of flowering plants. It shows that the wide dynamic range of the technique allows it to be used for the simultaneous determination of parts-per-billion levels of heavy metals including Pb, As, Cd, and Hg, together with high parts-per-million levels of nutritional elements, such as P, Ca, K, and Mg.

Research scientists in the cannabis field are tasked with validating robust methods that can be seamlessly transitioned into production laboratories. Unlike typical disciplines where controls are easily (and legally) obtained through known manufacturers, analytical chemists working for both consumable vendors as well as cannabis laboratories must do their best to develop methods often without such resources at their disposal. As the industry matures and additional regulations are adopted, the evolution of the pesticide testing subsection continues to be vastly different depending on the jurisdiction one does business in. This creates an interesting challenge for commercial scientists tasked with developing methods that will appeal to a majority of their consumers, while also generating unexpected hurdles to said laboratories once the methods are placed into production. This article provides an overview of best practices and method development techniques for pesticide testing in cannabis from a technical perspective. [ABSTRACT FROM AUTHOR]
