As soon as it enters your blood stream. Depending on the route of ingestion, that could be instantaneously.
Cocaine is detectable in urine as soon as 4 hours after first usage
not anytime soon
dont be daft.
Yes. Cocaine is only detectable in swab tests for a couple of days.
Depending on liver and kidney function, cocaine metabolites are detectable in urine. Benzoylecgonine can be detected in urine within four hours after cocaine intake and remains detectable in concentrations greater than 150 ng/ml typically for up to eight days after cocaine is used. Detection of accumulation of cocaine metabolites in hair is possible in regular users until the sections of hair grown during use are cut or fall out.
if you wash your hands as soon after it should not show up in your system at all
You were mistaken. Cocaine remains detectable in concentrations greater than 150 ng/ml, typically for up to eight days after cocaine is used.
Cocaine is only detectable in oral fluid for about 2 or 3 days.
Water does not clear cocaine from your system
Can cocaine be flushed out of your system in one day
How long does cocaine stay in your system?
For blood or urine sample, cocaine is out of your system in about 48hrs, unless they are going to take a hair sample (very unusual). Cannabis (marijuana) however remains detectable for up to 3 months!
