How long does cocaine stay in your system? This question is commonly asked by many who use this drug. Of course, there are many reasons individuals ask.

The fear of testing positive at work is one reason. Also, people tend to be curious as to when this damaging drug will completely clear from their system after they stop. Furthermore, some people may have legal reasons that require them to be clean from drugs.

It is difficult to say precisely how long cocaine will stay in your system. We know, for example, that your urine may test positive for up to five days after your last use. However, many factors can affect the specific length of time. Some of these reasons include age, metabolism, level of hydration, body mass, amount, and duration of use of cocaine.

In addition, the type of screening test done will determine the length of the detection period. Screening for cocaine in urine, blood, saliva, or hair will have different windows of detection. This duration can be as short as one day to as long as three months.


How Long Does Cocaine Stay in Blood, Saliva, Urine, and Hair?

Cocaine is one of the drugs found in most drug screening panels. If you use cocaine, it will likely show up in most testing done for work, legal purposes, or in medical clinics. Of course, this will depend on several factors, including the last day of cocaine use.

Note, however, that cocaine is broken up by the body quickly. What this means is that cocaine itself is not detectable in most screening tests. What is detected in the screening is a breakdown product of cocaine called benzoylecgonine. This chemical stays in the body much longer than the original cocaine.

Cocaine has a very short half-life of about one hour. Benzoylecgonine, on the other hand, has a half-life of about six hours. Ecgonine methyl ester is yet another metabolite of cocaine.

Even though the time frames differ somewhat, the average detection times are:

Blood: Up to 48 hours

Saliva: 1-2 days

Urine: 1-5 days (but up to 1-2 weeks in heavy users)

Sweat: 1-2 weeks

Hair: Up to 90 days (but longer in heavy users)

According to some reports, a heavy user can test positive on a urine test for up to 2 weeks. The reason for this is because cocaine stores in fatty tissues when people use it for a long time.

Although urine testing remains the standard, sweat patches are a convenient alternative. The reason for this is because they avoid some of the issues with drug testing — for example, privacy violations, possible disease transmission, and transportation of body fluids.

If you have concerns about how long cocaine stays in your system, you are better off stopping — especially considering the adverse effects of this drug.
