#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 I: Data Transparency in Cannabis Testing with Yasha Khan
November 21st 2024Evan Friedmann interviews Yasha Khan, co-founder of MCR Labs, about his journey into the cannabis industry and his efforts to promote transparency and integrity in laboratory practices. Yasha discusses the origins of MCR Labs, which began in Massachusetts to meet the needs of the soon-to-be legal medical cannabis market. He explains the challenges faced, including result manipulation by labs and the impact on public health. Yasha's Freedom of Information Act (FOIA) project aimed to gather testing data from 37 states, revealed significant discrepancies in potency and mold results. Despite some states' reluctance to share data, Yasha has made much of this data public, leading to collaborative research and publications on various aspects of cannabis testing.
Assessing Cannabis as a Harm Reduction Strategy: Insights from a Large-Scale Study
November 19th 2024A New Zealand study aimed to assess cannabis use as a harm reduction tool. Findings highlight lifestyle factors, and suggest cannabis-focused harm reduction strategies in reducing other substance use such as alcohol.
Ep 23, Part III: Accreditation in the Cannabis Industry with Susan Audino
October 24th 2024In Part III of this episode, host Evan Friedmann is joined by Susan Audino, PhD, founder of S.A. Audino & Associates, LLC, and co-founder of Saturn Scientific, LLC, to examine the complexities of sampling in the cannabis industry, emphasizing the need for proper sampling plans, and methods.
