Laboratory Evaluation of LAPD Drug Recognition Expert Procedures

Four Los Angeles Police Department Drug Recognition Experts independently rated volunteer subjects administered specific drug doses in a Johns Hopkins University study. The administered drugs included Marijuana, Diazepam, Secobarbital, and d-Amphetamine at multiple dose levels. The results indicate raters were accurate in identifying intoxication and the responsible drug class for subjects who received a drug.

Use Cases

• Validate drug recognition expert procedures based on controlled laboratory dose administration.
• Analyze rater accuracy for specific drug classes like stimulants and depressants.
• Model the relationship between drug-dose combinations and intoxication ratings.
• Compare expert performance across different intoxicating substances mentioned in the study.

Strengths

• Data originates from a controlled laboratory study sponsored by NHTSA and NIDA.
• Includes ratings from four independent expert evaluators for each subject.
• Covers multiple drug classes and dose levels as described in the experimental procedure.

Limitations

• Row count, column definitions, and file formats are unknown.
• Last update date is unknown; freshness unverified.
• The license is closed, which may restrict access and usage.
