Traditional cannabis preservation methods like glass jars or plastic bags fail to address the complex biochemical processes that lead to degradation. New packaging solutions create a controlled microclimate to maintain an ideal relative humidity between 58% and 62% and manage gas exchange to prevent degradation. This technology benefits cultivators with greater product stability, processors with higher-quality starting material, and consumers who receive a consistent product.

Conventional approaches for determining limits of detection (LOD), such as signal-to-noise ratios and repeated measurement methods designed for single-signal detection, can result in unrealistic LOD values because they often fail to account for multi-signal identification and the disproportionate generation of analyte and noise signals in mass spectrometry techniques such as selected ion monitoring (SIM) and multiple reaction monitoring (MRM). This article proposes a practical alternative compared to standard approaches.

Using Raman spectroscopy to measure potency in wet hemp and cannabis plant material would allow cultivators to analyze plants in the field without having to dry them. In experiments testing this methodology, Raman scans were able to correctly classify 93% of hemp samples as being above or below 0.35% total THC, and in cannabis, analysis of total THC had a relative error rate of 6%, which is below the 10% error rate allowed by many jurisdictions.
