Some marijuana convictions could be overturned in TN due to TBI testing issues

NASHVILLE, Tenn. (WKRN) — The Tennessee Bureau of Investigation’s drug testing procedures are being called into question, which could jeopardize marijuana convictions in the state.

Some marijuana-related cases in Tennessee could be overturned.

Earlier this year, the TBI alerted district attorneys statewide that the testing procedure the agency had been using for marijuana was in question due to the reliability of results.

Eighteenth Judicial District Attorney Ray Whitley told News 2 he has found at least four cases that are impacted in Sumner County, including one man who has had his 2020 conviction set aside and charges dismissed.

In a statement, the TBI said its testing is accurate as reported.

TBI has multiple testing methods related to marijuana. Currently, TBI’s instrumentation cannot determine THC-A present in the total THC. In cases where THC-A is relevant to the case, the Department of Agriculture is assisting with the testing, until our newly-acquired instruments and equipment are operational at the Bureau.

TBI spokesperson Susan Niland

The director of the TBI is expected to share more information on this situation Friday.
