It is an important aspect for consumers and regulatory compliance in the Cannabis industry. Pesticides and agricultural agents are substances used to control pests such as insects, fungi, and weeds. However, when Cannabis plants are treated with these compounds, there is a risk of residues remaining on the harvested flowers or plant material, which can pose health hazards if consumed. Mycotoxins can sometimes be found after a plant has been exposed to certain fungi, such as Aspergillus spp. Mycotoxin testing is included with pesticide and agricultural agents because of the chemical similarities and concentration ranges between these classes of compounds and the technology used to detect them.
Pesticide and mycotoxin testing of Cannabis products can be summarized by the following three steps:
- Sampling: Samples are collected from batches of Cannabis plants or products, such as dried flowers, concentrates, or edibles. The samples should be representative of the batch and taken from various locations to ensure accuracy.
- Instrument Analysis: Various analytical techniques are used to detect and quantify the presence of pesticides, agricultural agents, and mycotoxins in Cannabis samples. Our Arizona laboratory uses liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the determination of pesticides, agricultural agents, and mycotoxins.
- Data Review and Reporting: The data from the instrument test must be reviewed by a trained analyst. After review, the data can be uploaded to the lab information management system for certificate of analysis generation and released to the customer.
- Consumer: Cannabis products that contain excessive pesticide residues can be harmful when consumed. Testing helps ensure that products on the market meet standards and minimize potential health risks.
- Regulatory Compliance: Many jurisdictions have specific regulations regarding pesticide use in Cannabis cultivation. Testing ensures that producers adhere to these regulations and helps prevent the sale of non-compliant products.
- Quality Control: Pesticide testing is part of the quality control process for Cannabis products. It helps maintain consistency and ensures that products meet the desired quality standards.
- Transparency and Trust: Rigorous testing practices enhance transparency and build trust between producers, regulators, and consumers. Consumers are more likely to trust and purchase products that have undergone thorough testing.
