We're Enriching the Pesticide Conversation.

As you know, the California cannabis industry is in the midst of a regulatory revolution. A long road lies ahead to a stable regulatory environment, but Steep Hill is committed to remaining ahead of the curve and ensuring MMJ supply chains produce safe sources of cannabis. As part of this effort - and after months of diligent work with freshly minted protocols and brand new equipment - we are delighted to introduce our new Quantitative Pesticide Analysis.


What is Quantitative Pesticide Testing?

With Steep Hill, you get beyond an "indication of contamination" and start measuring the actual concentrations found in any sample of flower or concentrate. Use this new information to improve SOPs and tighten up your production line. We can help you identify issues and develop solutions: a great historical record of pesticide management could help you when it comes time to applying for a license!


84% of California Cannabis Isn't Fit for Consumption

Pesticide contamination has already proven to be a serious issue in legal markets like Washington and Colorado. With a lack of statewide regulatory oversight, view California cultivators have had to deal with stringent limitations on pesticide use. As a result, few have had the opportunity to examine how often each of the three most active California labs (CW Analytical, SC Labs, and Steep Hill) find pesticides in samples.

The four charts below compare the frequency at which pesticides are reported by the three most popular California labs. On the top right, we illustrate how often labs generally report a hit for pesticide contamination in flower samples. Next, we demonstrate how many samples would fail to pass into the market if a 1ppm (part per million) were the legal limit (Oregon currently stipulates a limit on each approved pesticide).


Myclobutanil Contamination is a Serious Risk

In the graph below, we illustrate how often samples hit for Myclobutanil contamination with a concentration that exceeds Oregon limits. California accounts for roughly 50% of myclobutanil use in the United States; it's estimated that grapes account for 60% of the total myclobutanil used in the state (via Toxipedia).
