CBD (cannabidiol) is a naturally occurring cannabinoid found in cannabis and hemp plants that does not produce intoxicating effects. Laboratories test CBD levels to verify product labeling accuracy and ensure compliance with regulatory definitions of hemp and cannabis products. CBD is commonly associated with products designed for wellness support, therapeutic use, and non-intoxicating cannabis consumption. Accurate CBD measurement is particularly important in the hemp market, where regulatory classification often depends on THC and CBD concentration thresholds. Both CBD and its acidic precursor CBDA are typically measured in a comprehensive cannabinoid potency panel.
