Cocaine: Blood tests can show Cocaine itself for about 12 hours after use. Urine tests check for metabolic byproducts of cocaine. In infrequent users a urine test is positive for up to 3 days after Cocaine use. However, in those who use Cocaine regularly, a urine test may be positive for 2 weeks after using. Hair samples can show Cocaine for several months after using. Best to stay away from using!

Agree with Dr. Pappas. Consult this site for information and stay off the drug. http://www.nlm.nih.gov/medlineplus/ency/article/003578.htm

3 days: With your usage history your urine test should be clean 3 days after last use.
