Lab Testing at Harborside

Harborside was the first dispensary anywhere to laboratory test cannabis. After being denied service by every commercial lab in the Bay Area, Executive Director Steve DeAngelo co-founded Steep Hill Laboratory, the first lab dedicated exclusively to cannabinoid analysis. Today, Steep Hill tests cannabis for dozens of dispensaries, and is the leading innovator in the field.

Harborside testing includes both safety screening and potency analysis. Product that fails to pass safety screening is returned to the grower, and never provided to customers. Potency analysis measures the percentage of THC, CBD, and CBN. Summarized test results are displayed in our sample cases and packages.

The testing program has two main components: safety screening and potency quantification. Safety screening analyzes and detects contamination of pathogenic molds, which can threaten the health of customers with compromised immune systems. Potency quantification provides the percentages of three major cannabinoids: THC, CBD and CBN. Later stages of the program will include the use of customer surveys to develop a comprehensive database of the efficacy of cannabis.

Harborside customers are able to access the testing results in three ways: labels in display cases, labels on products, labels on our website. Labels include percentages for THC, CBD and CBN; and are affixed to the products themselves.
