What Happens to Cannabis Products That Fail Lab Tests in Nevada?

Nevada permits the retesting and remediating of cannabis and cannabis products that have failed required testing. If a cannabis production run or lot fails required tests such as homogeneity, microbial screening, water activity, or residual solvents testing, the cannabis cultivator or production facility can request from the appropriate Board agent, an approval to remediate the lot or use them to make cannabis extract. Also, the Board will only authorize no more than 50 retests for failed production run or lot in a year. If a production facility does not request for the retesting of samples that failed required testing, both the sample and production run will be destroyed by the testing facility.
