Hippi Tea takes quality seriously. We have contracted with a fully independent testing laboratory to ensure our products meet the strictest standards. Listed below you will find the testing results for Concentration (how much CBD is in each serving) as well as testing for heavy metals, which can appear in lower-quality CBD products. Our goal is to provide you with 100% confidence in the quality of our CBD teas. If you have any questions about our testing processes, please let us know. We have also compiled a list of frequently asked questions about CBD tea.
