  1. Does compliant product testing require detection of all unapproved pesticides?

Many of the states only require testing a small portion of unapproved pesticides. For example, the Washington State Department of Health requires testing only the following unapproved pesticides: Abamectin, Bifenthrin, Chlormequat chloride, Daminozide, DDVP (Dichlorvos), Imidacloprid, Myclobutanil, Paclobutrazol, Permethrin, Propiconazole, Spinosad, Spiromesifen and Uniconazole.

2. Why not test for all unapproved pesticides?

According to the Washington State Department of Public Health, “Testing for that many pesticides would be very costly and most of the pesticides are unlikely to be used on marijuana. We don’t want to make these tested products so expensive that people can’t afford them.” However, the reality is that many other pesticides not on the list could be present. This will allow very dangerous pesticides to enter the distribution chain without any measures to detect them!

3. Are cannabis concentrates such as oils, edibles, and drinks more likely to contain pesticides?

Yes, pesticide levels rise dramatically in concentrates after the extraction process. That means a pesticide may be undetectable in dry flower/trim, but much more detectable in finished concentrates. In fact, between 80 and 90% of concentrates are contaminated with pesticide levels exceeding 400 parts per million (ppm)[1].
