California growers may want to take a page from their neighbors to the north when it comes to upholding cannabis quality standards.  

A new study from Steep Hill Labs suggests that much of California’s cannabis supply wouldn’t meet the stringent testing standards recently introduced by the Oregon Liquor Control Commission (OLCC).

As of October 1, all cannabis products in Oregon must be tested by labs certified by the Oregon Environmental Laboratory Accreditation Program (ORELAP), a requirement said to position Oregon as the state with the strictest standards in the industry.

Moisture, potency and pesticide levels are just a few of the mandated tests conducted by ORELAP labs on flowers, edibles and extracts from Oregon dispensaries. At least one major ORELAP certified lab has reported “a huge reduction in the use of pesticides” in the samples they’ve received from dispensaries in recent months.

“A year ago, when we first started testing product, we were finding very high rates of pesticides in the neighbourhood of 70 percent to 80 percent of the samples," Henry Grimmett, president of Portland’s GreenHaus Analytical Labs, told Civilized in a recent interview.

"Now we’re finding in the neighbourhood of 20 percent." 

Now, it appears California growers may want to consider adjusting their own practices. After applying the same testing standards used by ORELAP labs on a sample of California cannabis products, Steep Hill found that 83 percent of those products would have failed - largely due to the prevalence of myclobutanil, a compound that converts into toxic hydrogen cyanide when combusted. 

“Growers will significantly need to adapt their cultivation operations to address the high prevalence of pesticides,” reads a New Frontier Data press release, “both to meet the state’s new regulations, and to address the growing concerns among consumers about the quality of cannabis they are ingesting.”
