Understanding Drug Test Cutoffs
Drug test cutoffs refer to the minimum amount of a substance that must be detected in a sample to indicate a positive result. For cannabis, these levels can vary.
Common Cannabis Drug Test Levels
- 5 ng/mL: This is the most common cutoff for urine tests.
- 50 ng/mL: Often used for saliva tests.
- 20 ng/mL: Sometimes used for blood tests.
Why Cutoffs Matter
Cutoff levels are important because they help to reduce false positives and ensure the accuracy of the test. A higher cutoff means a lower chance of a false positive.
