ALCOHOL & DRUG IMPAIRMENT

Interpreting impairment evidence with scientific care.

A toxicology result does not, by itself, establish impairment at a particular time. Meaningful interpretation requires attention to the substance, dose history when known, timing, specimen type, observed findings, medical information, and the limits of the test.

Questions commonly considered

• What does the reported result establish?
• What does it not establish about timing, dose, or effect?
• How do pharmacology and individual variability affect interpretation?
• What other evidence is needed to evaluate claimed impairment?

Clear explanation for legal audiences

For attorneys and decision-makers, the task is to distinguish supported inference from speculation. Analysis is communicated in plain language while retaining the necessary scientific nuance.
