Pesticides can enter medical cannabis by means of direct application to the plant or by nutrient and water uptake. These pesticides are then present in the flowers and potentially consumed by the patient. Pesticides are especially harmful when found in concentrated cannabis samples. Many states adopt FDA pesticide safety guidelines; thus some farmers will use pesticide to treat their crops. Unregulated hemp-derived products are especially prone to pesticide contamination due to the large amounts of plant material required to extract hemp-derived byproducts. Our pesticide screening is performed by sensitive Gas Chromatography (GC) and Liquid Chromatography / Mass Spectrometry (LC/MS) which detect unsafe levels of pesticides in medical cannabis samples. Clients can know exactly how much pesticide is present, down to the part per million.
