When did you use the cocaine?

How long after using the cocaine did you (will you) have the test?

Is this the only use of cocaine, or have you used before? If so, when and how often?

I'm sorry, I was having some technical problems on my end....

While a single use of cocaine could theoretically give a positive, in most cases this is NOT the case. Hair tests typically need multiple uses over time to give a level high enough to register positive on a hair test.

Customer: replied 3 years ago.


it was used in febuary once as well as once in april

Expert:  Family Physician replied 3 years ago.
Since the detection period for hair tests is approximately 3 months - you would have had several uses during this period. This places you at a somewhat higher risk of a positive test.
