Who does cocaine 4 days before they KNOW they have a drug test?
Truthfully there is no real reason to tell if you are drug free unless you just don't do them.
Possibly (if the lab equipment is junk and the lab tech is both incompetent and stupid).
It is possible that a drug test can be passed for opiates and cocaine after 10 days clean.
If you have had dental work done that involved numbing one or more of your teeth, prior to two days before your drug-test, you can test positive for cocaine.
No, but you can not use cocaine and pass a drug test for cocaine.
Water in high quantities before a drug test dilutes your urine. Mix it with a B-2 vitamin to get some color to your urine. Cocaine is out of your body in approximently 3 days.
Cocaine can stay in the system for up to 10 days. Or in your hair indefinitely.
Maybe you should have thought of that before taking them.
No, Cocaine (coke) stays in your system for a max of 3 days.
