How Long Will Cocaine Stay In System When Snorting It?

The urine drug test that I administer can detect cocaine metabolites from 24 to 48 hours after use.

Cocaine can be detected in the urine of an occasional user for around 3-5 days.  Also, dont always count on urine being the chosen method of testing.  If they wish to use a mouth swab test, snorting cocaine and smoking crack cocaine can be detected for 5-10 days after use, the reason for this is the accumulation of cocaine in the oral cavity.  Hair test can detect usage for cocaine anywhere from 6 days after use, to 90 days depending on hair length.
