Steep Hill uses a series of high-tech machines and procedures to test the prepared samples, including gas chromatography, high-performance liquid chromatography and inductively coupled plasma mass spectrometry, which uses high-energy plasma to ionize a sample to look for contamination. The test results reveal a long list of useful information about each sample, including moisture content (under state regs, dried flower cannabis is required to have a moisture content under 15 percent), THC level and the strain’s unique profile of terpenes, the fragrant essential oils that contribute to the flavor and — according to devotees — medicinal benefits of each variety. To help guard patient safety, Steep Hill’s testing can also reveal a variety of potentially harmful contaminants, including pesticides, microbes like E. coli, heavy metals like lead and mercury and — if the sample is a THC concentrate or edible — residual traces of the solvents used to separate THC from the dried cannabis.
