How Often Should You Smoke for a Hair Test to Fail?
Understanding Hair Follicle Testing
Hair follicle testing analyzes the shaft of hair closest to the scalp, providing a long-term history of drug use.
The length of hair tested is often around 1.5 inches, which can reflect drug use up to 90 days prior.
This method is preferred for its accuracy and reliability in detecting historical drug use.
Factors Affecting Detection Duration
Dosage and Frequency: Higher doses and more frequent use can result in longer detection times.
Individual Metabolism: Variations in metabolism can lead to differences in detection duration.
Environmental Factors: Exposure to smoke or secondhand smoke can also affect detection times.
