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!
