Hi there, we are happy to help! Please always feel free to reach out to us if you have any questions or concerns, either in store, by phone or at Feedback@Theorywellness.org. We stand behind all our products and are happy to send you a COA for the vape you've purchased if you would be interested to see the testing results. There is a normal variation from extraction to extraction and batch to batch, depending on the flower, method, and type of product. Reach out to us in any way and we are happy to address these concerns with you. We look forward to hearing back!
