reLEAF Wellness Co. uses naturally extracted, USDA Certified Organic, whole plant hemp to create our CBD products. It is third party tested to certify the purity of our products. This is our 'T-Free' formula, which stands for THC Free or 0 THC in Vanilla Flavor. This is our Cannabidiol or CBD isolate so it only contains CBD. This is the product for those concerned about having any THC in their system. While we have the lab tests to show 0% THC in this product, because it's a Hemp product, it's not possible to guarantee a person wouldn't fail a drug test using ours or any THC Free CBD product.
