One of the reasons why we often say that drug testing is not credible is that all drugs do not stay in the human body for the same amount of time. In fact, some drugs remain in urine, blood, and hair longer than cocaine, ice and other potent drugs, such as marijuana.
Cocaine and its byproducts generally stay in the human system for one to four days after last use, but the substances can linger in the system even longer with chronic or heavy use of the drug.
Up to 90 days
Cocaine is detectable in a urine test for 3-4 days.
A blood test will detect cocaine for 1-2 days.
A saliva test will detect cocaine from 1-10 days.

Cocaine is a local anesthetic (painkiller) and a powerful stimulant of the central nervous system (nerves that control activities in our body). Cocaine can be inhaled, injected or smoked (crack).
The chemical name for the pure cocaine is 8-methyl-3-(benzyloxy) 8-azabicyclo[3,2,1]octane-2-carboxylic acid methyl ester. Molecular formula C17H21NO4, molecule.
Cocaine abuse methods include nasal aspiration/spraying, smoking, and injection. Generally, the dose is used, and the nasal inhalation is 10-30 mg/time (individually reported to reach 50-200 mg, the typical user will inhale the dose separately with two nostrils); if using the injection method 10-20 mg/time.
The extent of the action of these toxins into the human body is closely related to the way they enter.
The bioavailability of cocaine by intravenous injection (the amount of drug absorbed by the body) is 100%, oral administration is 20%-30%, and nasal suction is 20%. %-30%, fuel absorption is 6%-32%.
Among them, the most common route is nasal inhalation, one nostril is blocked, and the other nostril is used to inhale cocaine crystal powder.
The cocaine powder is divided into a plurality of rows or columns by sharps such as a razor, and one gram of cocaine can be divided into about 25-50 rows, each of which acts 3-5 cm, and contains about 25-30 mg of commercially available cocaine.
This medicine is then inhaled through a straw made from US dollar bills or by means of a cocaine “spoon”. In this way, the drug is actually absorbed through the mucosa, and the peak plasma concentration can be reached in about 15 minutes, but the clinical onset time is very fast.
Intravenous use of cocaine hydrochloride for approximately 3-5 minutes. If you use the most popular free cocaine in the black market, you can have a strong euphoria in 1min when inhaled for 5-10min. Its half-life is also different.
The average half-life of intravenous injection was 45 min, the oral half-life was 48 min, and the half-life from nasal inhalation was 75 min.
The lethal dose is 0.5~1g orally, 30mg orally for allergy, 30mg for intramuscular or mucosal administration, and lethal blood concentration iare0.9-21mg/L.
Cocaine can be absorbed quickly no matter how it enters the body. The difference is only the length of time and the strength of utility. Its metabolism is mainly achieved through liver tissue and plasma.
