This article addresses the US Department of Agriculture’s hemp testing rules and what laboratories should know regarding hemp testing. The author provides a short tutorial for laboratories and includes a section how laboratory information management systems (LIMS) can help.

In December, the US Department of Agriculture (USDA) announced an extension of the deadline for all hemp to be tested for tetrahydrocannabinol (THC) in Drug Enforcement Administration (DEA)-certified facilities only, citing a lack of approved laboratories.

Experts within the global cannabis and hemp industries discuss the importance of testing and regulations and sustainable measures that can reduce the sector’s environmental impact.

Dr. Heather Darby, an Agronomist with the University of Vermont, served as the program chair for the Hemp Track at Cannabis Science Conference East and gave the first talk to kick off the session on day 2.

The science of cannabis is in its beginning stages and has a large opportunity for growth advancement. Market Manager for Cannabis for Shimadzu, Eberhardt Kuhn, Ph.D., will be presenting two talks for both the hemp and analytical tracks, “Starting with the Roots - the Many Uses of Hemp” and “Delta Dawn - the Next Generation of Cannabinoids?” If you are interested in exploring hemp or cannabidiol (CBD) and other cannabinoids, check out both of these presentations to learn more! In this interview, Kuhn also discusses his interests in the cannabis industry and other presenters at the Cannabis Science Conference (CSC) West taking place in Long Beach, California from May 18–20, 2022.

Cannabidiol (CBD) has been a hot topic for several years now and it seems like you can buy CBD almost anywhere. As a consumer, how do you know that the CBD at your local drug store is the same quality at a cannabis or hemp retail store? Education is key to knowing the difference and finding a top-notch product. In this interview, Vince Sanders, founder and president of CBD American Shaman, discusses his company’s approach to cannabis retail, their main motivators for success, and his plans for continual expansion in the cannabis industry.

It is demonstrated in this paper that cell viability can be used to determine dose and response effects that are important in understanding toxicities and to detect differences in similar hemp products.

THC isomers are defined and discussed to better understand where they come from, how they are produced, and how they are being distributed.

Regulations and compliance are sometimes deemed a necessary evil, but consumer and employee safety are at the heart of those rules. The cannabis industry faces unique challenges when it comes to compliance because each state has their own rules. Federal regulation would certainly simplify matters, but until then Kim Stuck, CEO and founder of Allay Consulting, offers some practical advice for how to stay ahead of potential issues. Here, Stuck shares her background in regulatory work, the cannabis industry, her new blog coming out in Cannabis Science and Technology next month, and more.

Rylie and Janie Maedler along with Dr. Reggie Gaudino discuss the challenges in growing hemp for medical-grade CBD and Rylie’s Sunshine brand.

Better seed genetics, power-free tunable lighting, and other new scientific discoveries are making headway in what has become an ag-tech leading industry.

A closer look at the fundamental studies of tablet formation that are critical processes to ensure successful manufacturing of THC and CBD tablet dosage forms.

Isolated CBD, full-spectrum oil, and even smokable hemp are all being diluted down by a draconian regulatory framework that needs to be changed to facilitate growth, innovation, and prosperity throughout the industry.

Why the USDA’s requirements on what part of the plant to sample and how to obtain samples from the field are rife with problems and how to solve them.

There’s more hemp out there than the industry knows what to do with.

This column discusses where the USDA went wrong in their final rule regarding hemp and how the author thinks it can be fixed.

This article focuses on the technology being used in new rapid field tests that combine one-time-use color testing with a colorimetric panel that provides an identification and semiquantitation of THC and THCA.

Soil, water, and nutrient compositions play important roles in one’s quest to produce ultrapremium flower material; but unequivocally, it is lighting spectrum, coverage, and penetration that have the most influence over the terminal outcome, particularly in controlled environment agriculture.

Ric Cuchetto discusses the technology behind THC remediation and some of the challenges it presents.

Expert speakers in hemp testing, extraction and cultivation will educate industry professionals seeking to improve products, technology and service.

A rapid LC–MS/MS method is presented for the quantitative analysis of 16 cannabinoids in hemp samples with a single dilution protocol.

Cannabis Science and Technology® will host its first Hemp Science & Technology Virtual Symposium. Brian C. Smith, PhD, founder, CEO, and chief technical officer of Big Sur Scientific, will serve as the two-day event’s program chair.

Here a scientifically based representative sampling plan for hemp grows is presented, detailing how to collect composite samples, how many to collect, and how to analyze them.

A novel mid-infrared spectrometer that measures total THC in dried, ground cannabis plant material in 2 min is discussed as well as the applications of this analyzer for law enforcement, forensic laboratories, and regulatory agencies.

A proper set of hemp standard reference materials courtesy of the University of Kentucky are now available and the implications of this for hemp testing are discussed.

How quickly can a cannabis or hemp testing laboratory see return on investment?

How can we solve hemp testing problems such as representative sampling, composite samples, and insuring there will be enough testing capacity to meet the demand?

Dmitry Kurouski discusses the groundbreaking work his team is conducting using a handheld Raman spectrometer to identify cannabis and hemp plants.
