Summary

Roadside screening tests for cannabis impaired driving are crucial. Oral fluid tests show promise for detecting delta-9-tetrahydrocannabinol (THC) over legal limits, outperforming urine and observational methods, though further development is needed.

Area of Science:

  • Forensic toxicology
  • Drug policy and enforcement
  • Public health

Background:

  • Increasing legalization of recreational cannabis necessitates effective roadside impairment detection.
  • Driving under the influence of cannabis poses significant public safety risks.
  • Reliable roadside screening tests are essential for law enforcement and public safety.

Purpose of the Study:

  • To systematically review and evaluate the performance of roadside screening tests for cannabis use.
  • To compare the sensitivity and specificity of various screening methods against laboratory standards.
  • To identify the most promising tests for detecting delta-9-tetrahydrocannabinol (THC) in roadside settings.

Main Methods:

  • Systematic review of 101 studies sourced from six databases and grey literature (inception-March 2020).
  • Inclusion of primary studies evaluating roadside screening tests against laboratory analysis of blood or oral fluid for cannabinoids.
  • Focus on synthesis of sensitivity and specificity data for delta-9-tetrahydrocannabinol (THC) detection.

Main Results:

  • Oral fluid tests demonstrated higher specificity and lower sensitivity compared to urine tests when assessed against blood laboratory results.
  • Oral fluid tests showed higher sensitivity and similar specificity compared to observational tests against blood and oral fluid laboratory results.
  • Instrumented oral fluid immunoassays (Draeger DrugTest 5000 and Alere DDS 2) showed potential but require further validation due to imprecise estimates.

Conclusions:

  • Oral fluid screening tests offer the most potential for roadside detection of blood THC levels exceeding legal limits.
  • Continued development and rigorous testing of oral fluid tests are recommended for roadside cannabis screening.
  • Urine tests are generally not recommended, and observational tests require improved sensitivity for effective cannabis detection.
