Cocaine can only enter the body and subsequently the bloodstream if the person has inhaled the drug by ‘snorting’ a line through their nose, smoking it, injecting it or simply putting it in their mouth and digesting it.
Cocaine can therefore not be passed on if a ‘clean’ person kisses or has sexual contact with a person who has cocaine already in their system. Cocaine is an instant drug; which enters and leaves the body in a rapid amount of time compared to other recreational drugs. The ‘high’ or ‘rush’ cocaine produces only lasts around 20 minutes.
If a person has taken cocaine the drug can be detected in a urine sample for around 3 to 5 days after it was initially taken, although if the person is a very frequent user of the drug this can increase to around 2 to 4 weeks.
Urinalysis is the most common test type and used by federally mandated drug testing programs and is considered the gold standard of drug testing. Urine based tests have been upheld in most courts for more than 30 years, however, urinalysis conducted by the Department of Defence has been challenged for reliability of testing the metabolite of cocaine.
