As more states legalize cannabis, increasingly stringent testing requirements are being developed on the state level for pesticide and mycotoxin levels in cannabis products.
For U.S. states that have legalized the recreational or medicinal use of cannabis and cannabis products, there are presale testing requirements meant to address quality and consumer safety (1–3).
The cannabis industry has been taking a hard look at the science behind their products and the various contaminants that can inadvertently be added to consumer goods.
Using Method Detection Limits to Set Mandatory Reporting Limits for Banned Pesticides: How a Public-Private Partnership Improved Cannabis Regulation in Colorado
The regulation of pesticide use on cannabis is a complex issue for states with legalized marijuana.
Consumption of cannabis or cannabis-based products is currently legal in some form in 29 states in the United States plus the District of Columbia.
The method described here allows for the simultaneous analysis of 47 pesticides and five mycotoxins in cannabis in one simple QuEChERS procedure. This simple method is designed for implementation in start-up laboratories and in established laboratories that wish to streamline their sample preparation process, decrease solvent usage, and obtain accurate and fast results.
Well-established techniques used by the food safety industry, such as QuEChERS sample preparation followed by LC–MS/MS for the analysis of multiresidue pesticides, are evaluated for use with cannabis plant material.
Compact mass spectrometry, in combination with suitable sample introduction techniques—such as the atmospheric solids analysis probe, thin-layer chromatography, and classical liquid chromatography techniques—can be used effectively for the detection and quantification of cannabinoids and pesticides in cannabis-related material and contraband.
QuEChERS is introduced to the discipline of forensic testing as a viable method for the extraction of pesticides and cannabinoids in various complex sample matrices
