Recent advancements in biological cannabis testing enable precise identification and quantification of substances after cannabinoid exposure. Onsite urine tests detect recent cannabis use for up to five days, aiding legal and safety enforcement.

Area of Science:

  • Forensic Toxicology
  • Analytical Chemistry
  • Pharmacokinetics

Context:

  • Implementation of French drug laws and motorway safety regulations.
  • Need for rapid and reliable biological testing for cannabinoid exposure.
  • Advancements in analytical methodologies for substance detection.

Purpose:

  • To detail analytical progress in biological cannabis testing over the last decade.
  • To explain the role of onsite urine testing in enforcing drug laws.
  • To assess various biological matrices for cannabis determination based on recent data.

Summary:

  • Significant analytical progress allows accurate identification and quantification of substances post-cannabinoid exposure.
  • Onsite urine testing detects recent cannabis use for up to five days, supporting legal frameworks.
