Insects and other pests are common, if not ubiquitous, in both indoor and outdoor cannabis cultivations. If left unchecked, these pests can infest and destroy entire crops, sometimes in a matter of days. As a result, many cultivators use toxic chemical pesticides to avoid potential crop loss. Unfortunately, most of these cultivators are either unaware of, or choose to ignore, the potential environmental and health consequences of their actions.
Chemical pesticides are, by design, highly toxic and persistent. Many kill on contact and remain active for weeks, months, and even years. Human exposure to pesticides may lead to acute health problems, such as abdominal pain, dizziness, headaches, nausea, vomiting, as well as skin and eye problems. Many serious diseases, such as cancer, reproductive dysfunction, and asthma have been linked to pesticide exposure.
Patients deserve to know whether or not the alternative medicines they choose contain harmful pesticide residues. It is bad enough that pesticides are used on many, if not most, of the foods sold at our local grocery stores. Our medicines should be clean!
CW Analytical can verify the presence or absence of many commonly available chemical pesticides in dried flowers, keef, hash, oils, tinctures, and butters. Verify the safety of your medicines today.
We currently test for some of the most commonly available pesticides, including pyrethrins and pyrethroids. These are the products that are found on the shelves of your local home and garden store. We also test for some less common but highly toxic pesticides, such as Avid.
We use a combination of enzyme-linked immuno assays and gas chromatography to screen samples for pesticide residues.
All samples are first subjected to three independent enzyme-linked immunosorbent assays to verify the absence or presence of pesticide classes. The three assays screen for organophospate and carbamate pesticides, pyrethroid pesticides, and avermectins (Avid).
Samples are then analyzed by gas chromatography / mass spectrometry (GC/MS) to verify results and in some cases identify the actual pesticide residue detected by the immuno assays. Our GC/MS is calibrated regularly using known standards to ensure the accuracy of our test results.
