Tetrahydrocannabinol (THC)

A test of a small sample of products sold in the Twin Cities revealed amounts of THC past the legal limit.

In this article, we explore how cannabis extraction technology can preserve the acidic cannabinoids in the process.

A civil lawsuit filed in Arkansas by a medical cannabis patient alleges that three cannabis growers and one testing laboratory inflated the amount of tetrahydrocannabinol (THC) in numerous cannabis products.

In this article, we explore the difference in chemical profile between fresh and dry cannabis flower and why manufacturers may choose to extract frozen or dry cannabis.

This installment discusses new methods of cannabis production and manufacturers' reactions to the rise of the demand for cannabis artisan extracted products.

Part II of this series looks at the mechanism via which molecules move through HPLC columns and leads us to a discussion on the equations used to characterize separations.

There goes another year in the books. This review of 2022’s extraction greatest hits takes a look at discoveries, advancements in technology, and other highlights from the year. This article also lays out some predictions for 2023, which is set up to be an interesting year with less access to funding that could slow the development of new technology or innovation in the extraction space.

In part I in a new series of columns, we begin a discussion of the theory of chromatographic separations. Our goal is to derive equations that will help you better perform experiments to optimize your separations.

Currently in the life cycle of the cannabis industry, it is not obvious where the heavy metal regulatory landscape will end up. Clearly, the big four are not enough, but what is a realistic panel that reflects the real world of cannabinoid production?

The final part in this series of pitfalls to avoid and practicalities covers the importance of cleanliness, how many standards to run, how to spot outliers, and important experimental variables to control.

In the work presented here, the author shares research from collecting reports from the New Jersey State laboratory (the Department of Health’s Environmental and Chemical Laboratory Services), which has conducted testing for the state’s medicinal program. He documented an average variance of 20% in potency levels from different samples of the same test lot.

The third part in this series of pitfalls to avoid and practicalities to know about discusses the importance of validating and checking your calibration to ensure quality.

A review of the claims that differences in extract type can affect cost, ease of formulation, and the experience of the finished product.

In the work presented here, the authors pursue a more detailed understanding of the naturally rare occurring cannabinoid analogue, hexahydrocannabinol (HHC), by exploring the safety profile using a third-party lab to produce preclinical in vitro safety profile data. The purpose of these studies is to demonstrate HHC as a safe cannabinoid for potential human consumption.

This article examines why we should be studying the cannabinoids beyond THC and CBD in order to explore their potential medical value.

Part II of this series discusses how to measure absorbances properly, and compares the use of peak heights and peak areas in creating calibrations.

The various extract types are defined so there can be some consensus once and for all.

Here we discuss the importance of using standards that bracket the expected concentration range of standards in the unknowns, using the same chemical components in standards and unknowns, and making sure to minimize the error in concentration measurements of standards.

Part II of a guided tour through the protein structure and function influence of cannabinoid receptor 2 (CB2R) on cannabinoid signaling.

The new processed cannabis products continue to attract consumers—but black market influence causes hesitancy.

Terpenes can be tricky. Although cannabis is heavily regulated, since cannabis-derived terpenes do not contain tetrahydrocannabinol (THC) and other cannabinoids, they are not regulated in the same way that cannabis is.

A discussion on the selection of a “golden” potency method including what this method should look like, how we should go about choosing it, and more.

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

How does the pharmaceutical industry test better to avoid mislabeling problems?

In part I of this series on statistical concepts related to cannabis analysis, we introduce the normal distribution, standard deviation, and how to calculate precision and accuracy.

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

Here, we explore the evolution and rise of color remediation methods in-line with extraction.

Dr. Denise Vidot shares some of her research findings that examine the impact of phytocannabinoids on multiple diseases.

This study presents bioassays for CBD, which can be used to assess the neurotrophic bioactivity of CBD formulations.

Medical cannabis patients and adult-use consumers alike are faced with an overwhelming amount of options when they first enter a dispensary. Across the industry, producers are looking for ways to simplify things for consumers. One company, Volunteer Botanicals, recently partnered with an investment group to create cannabidiol (CBD)-based tablets that also combine other cannabinoids and have the potential to create a unique consumer experience. In this interview, Jason Pickle, co-founder and chief sales officer for Volunteer Botanicals, sits down to discuss this recent product, the need for standardization throughout the cannabis industry, and more.
