Like cannabinoids, terpenes bind to receptors in the brain and give rise to various effects. Different harvests may demonstrate dramatically different terpenoid profiles due to variances in growing and curing techniques. Lab-tested products are the only guaranteed way of knowing terpene potency. We use High Performance Liquid Chromatography (HPLC) and Liquid Chromatography / Mass Spectrometry (LC/MS) to isolate and quantify up to 20+ terpenoids present in medical cannabis samples.
