Book Description :

The surge of interest in cannabis-based medicinal products has put an extremely high demand on testing capabilities, particularly for contaminants such as heavy metals, which are naturally taken up through the roots of the plants from the soil, growing medium, and fertilizers but can also be negatively impacted by the grinding equipment and extraction/distillation process. Unfortunately, many state regulators do not have the necessary experience and background to fully understand all the safety and toxicological issues regarding the cultivation and production of cannabis and hemp products on the market today. Measuring Heavy Metal Contaminants in Cannabis and Hemp offers a comprehensive guide to the entire cannabis industry for measuring elemental contaminants in cannabis and hemp. For testing labs, it describes fundamental principles and practical capabilities of ICP-MS and other AS techniques for measuring heavy metals in cannabis. For state regulators, it compares maximum contaminant limits of heavy metals with those for federally regulated pharmaceutical materials. For cultivators and processors, it helps them to better understand the many sources of heavy metals in cannabis. And for consumers of medical cannabis, it highlights the importance of choosing cannabis products that are safe to use. Other key topics include: The role of other analytical techniques for the comprehensive testing of cannabis products Tips to optimize analytical procedures to ensure the highest quality data Guidance on how to characterize elemental contaminants in vaping liquids and aerosols Suggestions on how to reduce errors using plasma spectrochemistry The role of certified reference materials to validate standard methods Easy-to-read sections on instrumental hardware components, calibration and measurement protocols, typical interferences, routine maintenance, and troubleshooting procedures Written with the cannabis testing community in mind, this book is also an invaluable resource for growers, cultivators, processors, testers, regulators, and even consumers who are interested in learning more about the potential dangers of heavy metal contaminants in cannabis and hemp.

Book Description :

The availability (and the development) of innovative approaches to quantitative analyses and the data processing are often mandatory to deeply characterize a sample and to correctly highlight the analytical target. These objectives are carried out either by simply improving a single aspect of the analytical protocol or by developing a synergy of steps (from extraction to instrumental configuration to chemometric approaches) to obtain the maximum analytical information sought. Examples are innovative extraction protocols (also following the recent guidelines on green analytical chemistry) or new materials for the selective extraction of target compounds, multi-analytes screening methods, and "untargeted" approaches for food applications. In this text, the various articles are attributable to these elements, in particular, we start with a multi-analyte method for the determination of 10 different cannabinoids from Cannabis sativa L. by means of conventional techniques (Mandrioli and coworkers), to then see the application of techniques hyphenated "ultra-fast" by UPLC-MS for the authentication of food products (Xue and coworkers). The work of Song and coworkers on these applications in food products is also interesting, as it highlights how the collection process (and the timing of this passage) can affect the chemical profile and, consequently, the biological activity of Panax ginseng. Mocan and coworkers, applying an innovative extraction technique based on microwaves and applying well-known, robust, and easy-to-use instrumentation, have demonstrated how it is possible to discriminate between various species of Galium and how the chemical profiles obtained can support the biological activities observed. Similarly, but with the aim of developing new sample pretreatment procedures, Maggira and collaborators have developed graphene oxide-based materials for the selective extraction of sulfonamides in milk. Shen and coworkers apply a different type of approach, the "untargeted" one, for the geographical characterization of the Gentian Rigescens for which they combine chemometric techniques for the processing of raw chemical profile data. Wang and coworkers report a multiclass screening of drugs with high-resolution mass spectrometry through which they manage to obtain a high-scale, fast screening method for pesticides in fishery drugs based on ultrahigh-performance liquid chromatography tandem quadrupole-orbitrap high-resolution mass spectrometer.

Book Description :

An Informative Read for an Audience Interested in Why and How Medical Cannabis Helps Treat a Range of Illnesses—Maybe All of Them With cannabis approved in fourteen states (including the District and two US territories), medical cannabis approved in at least 35 states, and hemp (very-low-THC cannabis) off the controlled substances list, millions now treat their ills with medical cannabis or non-intoxicating cannabinoids like CBD. But lots of them don’t know why or how cannabis works in the body. Healing with Cannabis informs readers about an ancient biological system newly discovered in every vertebrate on the planet—the endocannabinoid system. This system is the only reason cannabis works in the body, and it’s why cannabis is effective in a broad range of disorders. The book offers an informal tone, a little humor, interviews with some of the most knowledgeable cannabinoid scientists, color images, and a selection of research and clinical trials to recount the story of the endocannabinoid system, its origins in the earliest forms of life on Earth, the evolution of its elements, and the discoveries, millions of years later, of more of its elements over time. Healing with Cannabis explains the surprising reasons evolution conserved the endocannabinoid system over a billion years and tells specifically how cannabis has positive effects on some of society’s most devastating illnesses, including neurodegenerative diseases, post-traumatic stress disorder, pain, movement disorders, cancer and chemotherapy, and addiction. The book also shows how medical cannabis, widely available, will change the face of public health, and how nearly everyone can benefit from this versatile medicine that has a 5,000-year history of safe and effective use.
