Does West Virginia License Independent Cannabis Testing Labs?

How Do Virginia Marijuana Testing Labs Submit and Report Test Results?

In West Virginia, the results of tests conducted on process lots samples requested by a grower/processor and harvest batch samples or harvest lot samples requested by a grower/processor must be submitted electronically. The electronic tracking system used for the reporting must be accessible to the grower or processor whose cannabis samples were tested and to the West Virginia Bureau for Public Health. The electronic tracking system, in this instance, is any seed-to-sale tracking system prescribed by the Bureau. At the grower’s or processor’s request, a cannabis laboratory can issue them a certificate of analysis (COA), including the supporting data, for each process lot, harvest lot, or harvest batch.

What Happens to Cannabis Products That Fail Lab Tests in West Virginia?

An approved marijuana testing laboratory in West Virginia may retest a sample of cannabis that fails any test required upon request from the processor or grower. However, a processor or grower must inform the state's Bureau of Public Health of its intent to retest that sample or test another sample from the same harvest lot, harvest batch, or process lot that failed the initial lab test. If an initially tested sample passes a retest, another licensed lab in the state must test a new sample from the harvest lot, harvest batch, or process lot to confirm the passing test result. However, if the Bureau refuses to accept the result of a test, the lab must dispose of the sample as stipulated in 64CSR110.22.
