How does the growth rate of hair contribute to the use of hair samples for drug testing?
How does the growth rate of hair contribute to the use of hair samples for drug testing?
- The rate of hair growth affects the sensitivity of the drug test, with faster growth leading to higher sensitivity.
- The rate of hair growth allows for an estimation of the time of drug use based on the location of the drug in the hair shaft. (correct)
- The rate of hair growth determines the concentration of drugs in the hair samples.
- The rate of hair growth influences the type of drugs that can be detected in the hair samples.
What is a potential concern raised by the use of hair samples for drug testing?

Study Notes
Hair as a Drug Testing Method
- Hair can record substance abuse over time, storing chemicals from the bloodstream in hair follicles.
- This provides a timeline of drug intake.
- Hair grows approximately 1-1.5 cm per month. Sections of the hair can pinpoint when substances were ingested.
- Hair drug testing isn't uniformly used, and variations in hair color and coarseness affect results.
- Darker and coarser hair tends to retain more drugs, which might introduce racial bias in drug testing.
