Forensic Science Scope of Work
Scope of Work and Expected Turn-Around Times
Controlled Substances (Expected average turnaround time within 90 days)
- Qualitative analysis and identification of substances controlled under the Federal Controlled Substances Act (CSA) or the Nevada Administrative Code (NAC).

- Only selected items from those submitted will be analyzed.
- When substances likely to contain a Schedule I compound are submitted, one of each type of substance will be analyzed.
- When a Schedule I compound is identified, substances likely to contain a compound in a lower schedule will not be analyzed.
- Visually similar substances will be tested when the total net weight could substantiate a trafficking charge. This may be deferred until the case is set for District Court.
- Residue and paraphernalia items only will be tested when no other controlled substance evidence exists.
- Pharmaceutical preparations (tablets or capsules)
- Identification of any controlled substance in one dosage unit when no other controlled substance evidence is present (except marijuana).
