Poisons

Other substances affecting human health

Key Responsibilities of the State Toxicologist under WAC 448:

Certification of Laboratories and Analysts

WAC 448 sets standards for laboratories and personnel performing toxicology analyses in legal and forensic cases.

Analysts must meet qualifications, including education and proficiency testing.

Standard Operating Procedures (SOPs)

Laboratories must follow scientifically accepted procedures.

The toxicologist ensures adherence to SOPs to maintain legal admissibility.

Reporting and Testimony

Results of toxicology tests must be accurate and reliable.

The State Toxicologist may be required to testify in court regarding testing methods and results.

Quality Assurance and Auditing

WAC 448 requires periodic review of lab procedures, calibration of instruments, and documentation of testing.

2. Important Sections of WAC 448

Some of the key sections include:

WAC 448-14-010 – Definitions

Defines terms like “toxicologist,” “analyst,” and “controlled substance.”

WAC 448-14-020 – Qualifications of Toxicologist

Requires a Ph.D. or equivalent experience in toxicology, chemistry, or related field.

Analysts must demonstrate competence through proficiency testing.

WAC 448-14-030 – Laboratory Standards

Labs must be certified by the State Toxicologist.

Emphasis on chain-of-custody, proper storage of samples, and adherence to SOPs.

WAC 448-14-040 – Evidence Handling

Requires proper labeling, tracking, and preservation of biological specimens.

WAC 448-14-050 – Reporting Results

Toxicology reports must be clear, complete, and scientifically accurate.

Allows the toxicologist to interpret results in court context.

WAC 448-14-060 – Court Testimony

3. Legal Standards Applied in Washington Courts

The State Toxicologist’s work under WAC 448 has been cited in many cases, often regarding:

Admissibility of toxicology evidence

Qualifications of expert witnesses

Accuracy and reliability of chemical tests

Key Legal Principles:

Expert Testimony (ER 702 – Washington Rules of Evidence)

The State Toxicologist is considered an expert witness under ER 702.

Courts evaluate if the testimony is based on reliable scientific methods.

Chain-of-Custody

Evidence tested by the State Toxicologist must show unbroken chain-of-custody.

Failure to follow WAC 448 procedures can lead to suppression of test results.

Laboratory Standards

Courts often defer to WAC 448 to determine if lab procedures are legally sufficient.

Ensures uniform standards across all toxicology labs in the state.

4. Notable Case Law Involving WAC 448

Here are some important examples showing how courts have interpreted or applied WAC 448:

a) State v. Oberhausen, 162 Wn.2d 596 (2007)

Issue: Whether blood alcohol test results were admissible.

Holding: Court emphasized that the State Toxicologist’s certification and adherence to WAC 448 lab standards ensured the reliability of results.

Significance: Demonstrates that WAC 448 procedures directly affect the admissibility of toxicology evidence.

b) State v. Myers, 145 Wn.2d 26 (2001)

Issue: Whether the State Toxicologist’s laboratory properly validated new testing methods.

Holding: Court ruled that tests performed in compliance with WAC 448 are presumed reliable, but labs must document all validations and QA/QC procedures.

Significance: Shows the critical importance of following WAC 448 quality standards.

c) State v. Williams, 123 Wn. App. 875 (2004)

Issue: Chain-of-custody dispute for drug evidence.

Holding: Evidence was admissible because WAC 448 evidence handling requirements were followed.

Significance: Confirms that proper sample handling under WAC 448 protects evidence from suppression.

5. Why WAC 448 Matters

Legal Reliability: Ensures toxicology results are scientifically valid for use in criminal and civil cases.

Uniform Standards: All analysts and labs in Washington follow the same rules, preventing inconsistent results.

Expert Qualification: Protects against unqualified individuals presenting toxicology evidence.

Court Trust: Judges and juries rely on WAC 448 compliance to accept test results in court.
