Tetrahydrocannabinol (THC)

All THC-containing products must be sold exclusively at licensed dispensaries only.

The FDA and FTC have sent warnings to several companies that market delta-8 THC edibles.

The NCAA is reconsidering changing their tune on cannabis and removing the plant from their banded drug list.

A tutorial article that delineates the rising threats of “lab shopping” and THC inflation to the US cannabis industry and proposes solutions to overcome them.

The webinar "Cannabis and Dementia: Unlocking the Potential" was held on June 14, 2023, and featured four panelists’ experiences treating dementia symptoms with cannabis.

Noting the current lack of an accurate cannabis breathalyzer, researchers in a protocol development study analyzed levels of THC before and after participants smoked cannabis.

This article provides insights into the opportunities involving the genetic modification of cannabis.

The current challenges and future perspectives of the purification of cannabinoids from cannabis extracts are presented in this review article.

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.
