The metabolite “Benzoylecgonine” which is produced after the ingestion of cocaine is different from marijuana with regard that Benzoylecgonine is water soluble. Therefore, cocaine is passed out of the body more quickly than marijuana. Cocaine is primarily metabolized by the body's liver and then excreted through our kidneys and then out of our system through our feces and urine. The remaining cocaine metabolites which are not easily pass through our body’s excretion process ultimately end up stored in the body’s fat cells. A person’s body mass index or BMI, (body fat percentage), is a big factor to consider when figuring out how long cocaine and its metabolites stay in our system. The higher a person's BMI the longer cocaine will remain in present in urine.
The frequency of cocaine use and the potency of the cocaine are the next major factors to consider when calculating how long does cocaine stays in your system. A person who uses cocaine on a daily basis is going to have more cocaine metabolites than someone who uses cocaine less frequently. The strength of the cocaine needs to be consider when determining how long cocaine remains in our system. Cocaine comes in many different strengths, and it is relatively impossible to know exactly what degree of purity of cocaine a person is ingesting when using. This is one of the reasons that nobody can accurately predict how long cocaine actually stays in the body.
These are the major factors which contribute to how long cocaine stays in your system, we can predict how long the body will continue to show evidence of cocaine usage. It has been suggested that evidence of cocaine usage can be detected by drug testing for up to 5 days in most instances. This time frame is not accurate in many cases. Some people can show evidence of cocaine usage for periods of time far greater than 5 days, in some rare cases up to 30 days.
