#4. Factors Influencing Yields in Extraction, Part I: Understanding the Influence of Starting Material and Performing Extraction CalculationsBy Krista Kulczycki and Aaron Godin
At a glance, modern extraction machines can seem a little mysterious: plant material is added to an extraction chamber, processing parameters are chosen, the extraction process is carried out, and an output of material is collected. Part I of this series examines the two main biologically-inherent starting-material influences.

#5. Making Sense of Cannabis Strains Through Chemometrics in ReviewBy Cindy Orser and Philippe Henry
The cannabis industry is constrained by the continued use of acronyms and nonstandard abbreviations for strain naming in lieu of a scientific-based standardized classification convention or lexicon. Applying chemometric tools can result in not only the authentication of a given cannabis cultivar but also provide a quality control mechanism for both cannabis flower and any resulting cannabis-based drugs.

Figure 2: Probability sampling methods: (a) Random sampling. (b) Systematic sampling where there is a method where every nth sample is chosen. (c) Stratified sampling in which samples are grouped and randomly sampled. (d) Cluster sampling is used when the population is very large and divided up by physical or geographical areas and all units within subset are sampled.
#7. Right From the Grow: A Look at Sampling and Sample Preparation Methods of Solid Cannabis for AnalysisBy Patricia Atkins
Laboratories are challenged with highly regulated and difficult sample schematics, sample preparation, extraction, and testing procedures that try to ensure accuracy and precision of testing. Accuracy in analytical testing starts at the very beginning with sampling and sample preparation prior to testing.

Ep 24, Part III: Data Transparency in Cannabis Testing with Yasha Kahn
December 26th 2024In the final part of this episode, Evan Friedmann and Yasha Kahn discuss the need for a national entity to centralize cannabis data collection, moving from snapshot data to continuous updates. They emphasize the importance of accurate lab data and adverse event tracking, suggesting QR codes on packaging to report issues. Yasha suggests harsher consequences for result manipulation and suggests collaboration between state departments and federal entities to support underfunded regulators. They also discuss the potential benefits of off-the-shelf testing and the importance of stability testing. Finally, Yasha shares his top three reading recommendations for the audience.
Ep 24, Part II: Data Transparency in Cannabis Testing with Yasha Kahn
December 12th 2024Evan Friedmann and Yasha Kahn, co-founder of MCR Labs, discuss the discrepancies between current regulations and data on mycotoxins and pesticides in cannabis products. They highlight the need for updated regulations based on new data, emphasizing the importance of accurate testing and labeling. They also discuss the issue of result manipulation, particularly in THC content, and the need for public health officials to address this. Yasha suggests making testing data public to enhance oversight and suggests a national entity to manage this data for better consistency and public safety.
