Will Cocaine Taken 11 Days Ago Show In The Urine Sample?

There is very little chance of detection in urine.
Detailed Answer:
Hello XXXX
Thanks for writing to HCM
Cocaine itself is metabolized very rapidly and it can't be measured in routine urine screening.When urine is being screened for the presence of cocaine,we actually measure benzoylecgonine(a metabolite of cocaine).
There is no universal rule for its total excretion through urine.It is debatable.
The widely accepted time period for benzoylecgonine to be cleared from the urine is 3-5 days.
Some study claims that benzoylecgonine can be detected in heavy cocaine users for 10-14 days.
You have taken 10 days ago and you are supposed to be tested after 10 days,so there is very little chance of its detection in urine.It can be assumed that you are safe.
Get well soon.
Hope I have answered your question.
Further queries are most welcome.
Take Care
