Testimony & Case Review

When the drug test result is the evidence.

Independent interpretation of urine and oral fluid drug testing for legal and administrative proceedings. Testimony experience centered on drug court and community supervision matters. Every case begins with a no-cost conflict and merit screening.

Scope and Credentials
📋
Stated plainly, so there are no surprises on cross. William L. Bundy Jr. is a licensed pharmacist (Virginia and Florida) and a clinical toxicologist with more than 15 years in pain management, addiction medicine, and drug test interpretation. He is completing an M.S. in Clinical Toxicology at the University of Florida (expected 2026), is an active member of the Society of Forensic Toxicologists, and serves as a Clinical Assistant Professor at the University of Florida College of Pharmacy. Testimony to date has been primarily in drug court and community supervision matters. Written case review and opinion work is available more broadly in matters involving urine and oral fluid drug testing.
Where This Matters

Drug testing evidence is routinely treated as settled fact when it is not. Immunoassay screens cross-react with common medications, detection windows get read as proof of use on a specific date, and presumptive positives get acted on without confirmation. These are the situations where that distinction changes the outcome.

Drug Court & Problem-Solving Courts
Primary area of testimony experience

Sanction and termination hearings turning on a contested result. Common issues include presumptive positives never sent for confirmation, cross-reactivity from a prescribed medication, EtG interpretation and incidental alcohol exposure, and cannabis results misread as new use when the pattern reflects residual excretion.

Probation, Parole & Supervision
Violation proceedings built on testing

Violation matters where the alleged evidence is a positive screen. Review covers testing protocol, cutoff selection, specimen validity, whether confirmation was performed, and whether the result supports the conclusion drawn from it.

Written Case Review & Opinion
Available more broadly

Record and laboratory review with a written opinion, in matters involving urine or oral fluid drug testing. The analytical questions are the same across venues even where the procedural context differs, and this work is offered independently of testimony.

Rebuttal & Second Opinion
Review of an opposing report

Assessment of an opposing expert report or a laboratory's interpretation, identifying methodological gaps, unsupported inferences, and points where the analytical data does not support the stated conclusion.

How Engagement Works
STEP 01
Case screening, at no charge

Send the matter and the testing at issue. Every case receives a conflict-of-interest and scientific merit review before engagement is confirmed. If the science does not support a favorable opinion, or if the matter falls outside current experience, you will be told at this stage rather than after a retainer.

STEP 02
Engagement and retainer

Engagement is confirmed by a written agreement with the fee schedule attached. A $1,000 retainer is required before work begins and is applied in full against the final invoice. No opinions are expressed until the retainer is received.

STEP 03
Analysis, report, testimony

Record and laboratory review, written opinion, and deposition or hearing testimony as the matter requires. Invoices are issued at case milestones or monthly for ongoing matters, payable within 30 days.

Fee Schedule

Rates are published so you can evaluate fit before the first call. Case screening is not billed.

Independence
⚖️
The duty runs to the court, not to the retaining party. Opinions are based solely on the scientific evidence, applicable laboratory standards, and peer-reviewed literature, and are never contingent on the outcome of a proceeding. Cases are accepted from either side. Dr. Bundy is employed as a clinical toxicologist at Millennium Health; ToxiPharm LLC operates independently, holds no financial interest in any laboratory or testing product, and does not recommend specific vendors. Full disclosures appear on the About page.
No-Cost Case Screening
Send the matter. Find out if the science supports it.

Describe the case and the testing at issue. You will receive a conflict and merit review at no charge, and a straight answer about whether the analytical evidence supports the position you need.
