At Sherlocks Glass & Dispensary, transparency and trust are at the heart of everything we do. That’s why we provide third-party Certificates of Analysis (COAs) for every THCa pre-roll we carry—so you can shop with confidence. Below, you’ll find an alphabetical list of lab-tested results for all our current THCa pre-roll strains. These certificates verify cannabinoid content, confirm legal compliance under the 2018 Farm Bill, and ensure there are no harmful contaminants like heavy metals, pesticides, or residual solvents. We only stock premium pre-rolls made from exotic, top-shelf flower—not shake or trim. Whether you’re shopping in Raleigh or Durham, NC, or browsing online, these COAs give you full insight into the quality and potency of what you’re consuming. Every batch is tested and published to uphold our commitment to safety, compliance, and premium cannabis products.
