How Long Does Cocaine Stay in Your Blood?

Cocaine is a fast-acting stimulant drug that affects the central nervous system. When snorted, smoked or injected, cocaine enters the bloodstream and passes through the liver, where it gets broken down into two inactive metabolites, benzoylecgonine and ecgonine methyl ester. These metabolites get excreted from the body through urine. Cocaine has a short half-life, meaning it only takes an hour for half the cocaine in the body to be eliminated. However, it may remain detectable in certain drug tests for a longer period of time.

The amount of cocaine used and the way it was consumed can influence how long it remains in a person’s system. Individual tolerance levels are also important. Regular users tend to develop a higher tolerance and may need to consume more of the drug to feel the same effect. The metabolic rate of a person’s body can also impact how quickly the drug leaves their system. Some people’s bodies metabolize drugs more efficiently, while others process them slower.

Whether or not a person has a high tolerance to cocaine and how frequently they use it also impacts how long the substance will stay in their system. Cocaine and its metabolites can typically be detected in a saliva test for up to two days, in a blood or urine test for 2-3 days after use, and in hair tests for months to years in heavy users. The most reliable method for detecting cocaine is with a sweat patch drug test, which involves wearing a bandage over the skin to monitor the presence of inactive metabolites through perspiration.
