Top 5 Analytical Challenges for Pesticides in Cannabis

Aug 27, 2019 | Blogs, Food / Beverage | 0 comments

Now that cannabis is legalized in a majority of the United States and Canada, new regulations to help protect consumers lead us to an important question: What are they getting? Here, we’ll help provide the answer.

Some of the main goals behind cannabis regulation are to ensure that consumers know what’s in their cannabis and that the products aren’t contaminated with things like harmful pesticides. One evaluation of the most readily available CBD products in the US (from online retailers) showed only 31% were accurately labeled for CBD concentration. The study highlighted the need for manufacturing and testing standards and general oversight of cannabis products.

State testing regulations for pesticides in cannabis products are inconsistent. For example, California implemented mandatory testing shortly after legalization in early 2018, but Washington has prohibited the use of certain pesticides and doesn’t require any testing. There are all sorts of reasons why cannabis can become contaminated with pesticides, but the only way to know for sure is to test. In California, 3,373 batches of cannabis products failed safety testing between July 1 and November 30, 2018. Of those failures, 700 rejections were because of pesticides.

While the enforcement of mandatory pesticide testing remains a challenge for some, there are also analytical challenges that cannabis testing labs need to overcome.

Cannabis Analysis That’s Up to the Challenge
When it comes to making your lab operations more efficient and productive, you need a high-performance instrument that’s tough enough to handle routine cannabis testing and to meet the needs of ongoing regulatory changes. You need an LC-MS/MS solution that can stand up to these common testing challenges:

A “dirty” matrix
Measuring trace-level contaminants
Method development
Application support
Training

SCIEX offers world-class solutions designed to simplify your workflows and get you operational as quickly as possible. Explore the incredibly sensitive SCIEX Triple Quad™ 6500+ or QTRAP® 6500+ system featuring advanced SCIEX technology, combined with our vMethod™ and our expert application support and training.

Understanding PFAS and its impact on U.S. drinking water

In recent years, per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals,” have become a growing topic of interest due to their persistence in the environment and potential health risks. These synthetic compounds have been widely used in various industrial applications and consumer products since the 1940s. PFAS can be found in the air, soil, and water, and studies have shown that most people have detectable levels of PFAS in their bloodstream. One of the main exposure pathways for humans is through drinking water, particularly in communities located near industrial sites, military bases, or areas where firefighting foam has been used.

Selecting an LC-MS system for quantitation of pharmaceutical drug development

We understand you are busy, needing to prioritize running instruments, reporting results and managing your laboratory to meet deadlines. We created a solution guide to explain how SCIEX systems fit in the drug development pipeline to save you time evaluating options.

Nitrosamines: Where are we now?

Nitrosamines are a large group of N-nitroso compounds that share a common functional N-N=O group. They are produced by a chemical reaction between a nitrosating agent and a secondary or tertiary amine. Back in 2018, nitrosamines suddenly found themselves in the spotlight when they were unexpectedly detected in medications for high blood pressure. Since then, they have been found in several other prescription medications, including those for heartburn, acid reflux and diabetes, resulting in manufacturers recalling some common medications.
