Litigation Support for Drug, Alcohol,
and Impairment Cases

Bridging science and applied experience to clarify impairment evidence.

Practice Areas

Our litigation support practice focuses on cases where alcohol, drugs, or impairment are central to questions of conduct, causation, or responsibility.

  • Dram Shop & Overservice Litigation

    • Evaluation of alcohol service practices and timelines
    • Visibility of impairment based on observed behavior and context
    • Integration of receipts, surveillance, witness statements, and toxicology
    • Assessment of intoxication relative to service, departure, and driving times
    • Alcohol calculations: retrograde extrapolation, Widmark equation, and others
  • DUI & Drug-Impaired Driving Crashes

    • Alcohol- and drug-related motor vehicle collisions
    • Interpretation of toxicology results in light of testing context
    • Evaluation of impairment versus mere presence of substances
    • Reconstruction of impairment and evidence timelines relative to driving behavior
  • Other Impairment-Related Matters

    • Workplace incidents involving alleged impairment
    • Injury or death cases alleging drug or alcohol contribution
    • Cases with limited, delayed, conflicting, or absent testing
    • Foreseeability and notice questions tied to observable behavior

How We Support Litigation

Our work sits at the intersection of science and the field. Attorneys use us to bridge the gap between laboratory data, investigative records, and how impairment is actually evaluated and documented in real cases.

Support commonly includes

  • Interpreting toxicology and pharmacology evidence in context
  • Performing alcohol calculations, including forward and back extrapolations
  • Evaluating reasonable suspicion indicators and behavioral observations
  • Developing timelines from reports, video, testing, and scene evidence
  • Reconciling conflicting or inconsistent records
  • Assisting with case strategy and preparation for examining other experts
  • Integrating scientific, observational, and contextual evidence into a coherent account of events

Areas of Expertise

Our litigation support draws from multiple, complementary domains, including:

  • Human Performance & Toxicology

    • Human performance toxicology
    • Analytical and forensic toxicology
    • Alcohol pharmacokinetics and impairment modeling
  • Field Investigation & Evidence

    • Law enforcement field investigation of impairment
    • Reasonable suspicion evaluation and documentation
    • Interpretation of investigative and medical records
  • Causation & Applied Context

    • Crash investigation and impairment-related causation
    • Alcohol service practices and server training programs
    • Integration of behavioral, scientific and contextual evidence

Expert Team Model

The practice is led by the founder, who oversees scoping and methodology and matches each matter to the appropriate expert or expert team.

In many matters, a single expert with expertise spanning multiple domains can address several angles of a case. In others, a coordinated team approach ensures that each issue is evaluated by the most appropriate expert or combination of experts—without unnecessary duplication.

The goal is always the same: matching the expertise to the evidence and the legal questions at hand.

Types of Engagements

Engagement Options

Choose a case-by-case engagement when you need targeted expert support for a specific matter. If your firm handles recurring dram shop or impairment litigation, an annual plan provides ongoing access to our expert team across matters at a preferred rate.

  • Case-Based Engagement

    Best for

    • One-off matters requiring expert input
    • Firms that infrequently handle dram shop, DUI, or drug impairment cases
    • Cases with defined scope or strict budget constraints

    How it works

    • Engagement is tied to a specific case
    • Upfront minimum case fee applies
    • Work may include evidence interpretation, calculations, timelines, written opinions, affidavits, or testimony
    • Standard pricing model applies for case-based work
  • Annual Firm Access Plan (Annual Term)

    Best for

    • Firms handling recurring dram shop or DUI / impairment cases
    • Attorneys who want fast, reliable access to expert input throughout the year
    • Practices that need flexible support across multiple matters

    How it works

    • A fixed bank of hours funded for use over a one-year term
    • Hours may be used across any number of matters, with no minimum hours per case
    • Use hours for quick questions, targeted evidence interpretation, timeline review, calculations, consulting support, and strategy-focused calls
    • Preferred hourly rate compared to case-based engagements
    • Unused hours expire at the end of the term and renewal is required for continued access
    • Case assignments are matched to the most appropriate expert or combination of experts on our team, based on the issues involved
