| Requisition: | |
| Reference Values: |
Positive ≥ 50 ng/mL
Significant increases in urinary levels of cannabinoids from passive inhalation have been reported to occur only after exposure to extremely high concentrations of marijuana smoke in small unventilated areas. Cannabinoid concentrations resulting from passive inhalation are not likely to exceed 20 ng/mL which is below the cuttoff value of 50 ng/mL. |
