Factors That Influence How Long Does Coke Stay In Your System

1. Dosage of Cocaine

How long does crack stay in your system for a drug test will depend on the ingested dosage.  If you ingest a large amount of cocaine, it’ll take longer time for its active metabolite to fully clear from your body.

2. Means Of Administering Cocaine

One of the factors that can influence the detection period of cocaine in your body is the means of its administration. Normally cocaine can be taken orally, through intravenous injection, smoked or snorted.

Snorting Coke

People who snort snow (cocaine) will get a high that will last between 10-30 minutes. This modality of administering cocaine is associated with an elimination half-life of nearly half an hour.

This means that it would take nearly 2.75 hours for cocaine to be eliminated from your body. However, its metabolite – benzoylecgonine can be detected for a much longer period.

Normally, the cocaine dosage among people snorting it is greater than those who inject it. As a result, coke can be detected in the system for a longer period.

Smoking Cocaine

Those who resort to smoking cocaine will get a high much faster than the one ingesting orally. The elimination half-life of coke is nearly 45 minutes if you have smoked it. This means cocaine will be eliminated from your body within 4 hours.

However, benzoylecgonine, cocaine metabolite can be detected for a longer time duration in your body.


Intravenous Injection Of Coke

Individuals that inject cocaine intravenously will get high within minutes of injecting it. The period of its effect will be between 5-15 minutes.

The elimination half life of cocaine, in this case, will be around 5 minutes. The drug would be cleared from the system within half an hour, but benzoylecgonin will be detected for a longer duration.

Coke will be cleared quickly from the body of the person injecting cocaine because of the quicker onset of action.

Oral Ingestion

3. Time Span

If you’re ingesting cocaine for a long-time, then let me tell you that coke will stay in your body for a longer duration. On the other hand, if you’ve recently started taking cocaine, it’ll stay in your body for a shorter period.

The chronic cocaine use will lead to the storage of metabolites within fatty tissues, like liver. Coke metabolites will continue accumulating within these fatty tissues with each usage. As a result, your body will take significantly longer time to fully detoxify from cocaine.

4. Frequency Of Drug Use

Besides time span over which any person has been ingesting coke, frequency of its usage also plays a vital role in determining the detection period.

For instance, a person ingesting cocaine 25 times a month may find that cocaine will stay in their system for much longer than a person ingesting only 3 times a month.

Actually, when a person takes coke frequently, neurophysiological adaptations will take place. It’ll slow down the process of drug clearance from the body.

5. Purity Of Cocaine

Cocaine purity may influence detection period

Unlike cannabis that has different strains, cocaine isn’t modified to have these effects. It’s generally sold as: freebase (crack) or cocaine hydrochloride (powder).

Coke is mixed with other chemicals by many drug dealers to elicit a different effect among the users.  However, the detection period of cocaine in your system will not be affected much after mixing. The particular factor that can affect on how long does crack cocaine stays in your system is the purity.

If you’ll take highly purified cocaine that has not been mixed to increase its weight will contain a greater amount of the active ingredient. As a result, coke will be retained within your body for a longer period.

If you’ve ingested diluted cocaine, it’ll have less active ingredient and consequently your system will be cleared quickly.

Normally, a standard hair test, including GC-MS confirmation requires 100 mg sample of hair (90-120 strands). The collector will cut a minimum length of 1.5 inches of hair from the scalp. The reason for it is quite simple – Human head hair grows at an average rate of about 0.5 inch per month.

However, cocaine hair test has a disadvantage – It cannot detect the presence of coke in new cocaine users. Because, it usually takes nearly a week for cocaine metabolites to get detected in hair follicles.

Sometimes, it can happen that your hair can become contaminated with cocaine from the external environment. Normally, a good hair wash will be able to remove these external contaminants.

But, you don’t need to worry about it as the test examines only the amount of cocaine metabolites inside the hair follicles. Those external contaminants will have no effect on the hair drug test results.
