However, the actual time that crack cocaine takes to get out of your system remains relatively short; around 24 to 48 hours based on saliva, urine, and blood tests. The only drug test that would reveal crack use for months and even years after use is testing the hair of an individual.
Drug tests done on the hair of a crack cocaine user will reveal the presence of the drug for far longer than other tests can. For this reason, it is the preferred way to test for crack cocaine use in court cases such as those involving child custody. Hair is technically not alive, and can, therefore, retain traces of crack for a long time. In hair, traces of crack may be present for several months to years.
Whether someone is trying to pass an employment drug screen or is trying to determine if their child is using drugs, there are a variety of reasons someone would ask how long can crack stay in your system.
Methamphetamine, often referred to as ice or crystal meth, is a stimulant with a rapid onset. The initial rush lasts for about 30 minutes, and the high that follows can last for several hours. The average half-life for meth is about four to five hours. Your body excretes some meth without metabolizing it at all. But tests can detect chemicals that your body produces as it breaks down the remaining meth.
This medication is usually taken orally and can take some time to produce effects. The average half-life of the drug is about 4 hours. If you take the drug for pain, you might stop feeling the therapeutic effects hours before the drug is fully eliminated from the body.
The best way to eliminate drugs in your system is to stop taking them. The drug detection times listed above are based on the last dose. As more time passes, the drug is less likely to show up in a toxicity panel.
Drug tests detect crack via the same methods used to detect powder cocaine. While blood, hair, saliva, sweat and urine can all be tested for signs of crack use, urine tests are the mostly commonly used.
The chemical is created when the liver breaks down cocaine. It reaches the highest levels in urine four to eight hours after last use and normally remains present in urine for up to four days. Chronic crack users will test positive for five days, on average, or longer.
While a blood test may be useful to confirm a cocaine overdose or a cocaine-related accident, the drug remains in the blood for about one day. The short detection window of blood tests makes them a poor drug screening method for employers, courts and others.
Sweat tests for cocaine and crack cocaine use skin patches to test for the drug, but they are uncommon. Typically, the individual will wear the patch for a week at a time and will test positive if they use within that seven-day window. The patch can also determine if a person used cocaine one to two days before the patch was applied.
Benzoylecgonine, however, has a longer half-life of approximately 12 hours. That means that after 24 hours, 25 percent of the drug is still in the body, and trace amounts can remain detectable for days.
According to the Substance Abuse and Mental Health Services Administration, a person who uses cocaine or crack just one time might test positive for only a day after last use. But people who smoke or shoot large amounts of crack, or use it regularly, will probably test positive longer.
Following a binge, a person can test positive for crack use for up to 10 days. In extreme cases, benzoylecgonine has been detected in urine up to 22 days after last use. According to a 2004 study in the journal Therapeutic Drug Monitoring, chronic cocaine users who test positive weeks after last use sometimes use more than 10 grams of cocaine per day.
When people with a crack addiction suddenly stop using the drug, they develop cocaine withdrawal symptoms. Unfortunately, this just reinforces the vicious cycle of addiction. The only way to relieve the symptoms is to continue using crack.
When crack enters the body, the effects occur in less than a minute and peak around five minutes. Overall, the high produced only lasts about 30-60 minutes. Even though crack stays in the system for varying lengths of time, the high is short-lived, which often leads people to compulsively seek increasing amounts of the drug.
A number of reviews and major papers currently exist for various aspects of drugs and drug testing in oral fluid. These include its use as a diagnostic tool,5 workplace applications,6 applications in drugs in driving,7 legal issues associated with drug testing in oral fluid,8 and detection times and pharmacokinetics of selected drugs.9,10
Buprenorphine is widely used for the treatment of opioid dependency and is available (amongst other formulations) as a sublingual tablet.36,37 The local absorption of drug in the mucous membranes of the oral cavity produces a depot-like effect for some hours after administration of drug. In the terminal phase of elimination oral fluid concentrations were similar to plasma.38 Nevertheless, the data suggested that oral fluid could be used to monitor the use of this opioid. A similar depot effect occurs with nicotine. Research suggests that measurement of the major metabolite cotinine is more useful than nicotine to determine exposure to this drug.39,40
In the laboratory, terms such as false positive (FP) and false negative (FN) are used. FP refers to a situation when a presumptive initial test result is not confirmed. FN refers to a situation when a confirmation test finds a drug present that was not detected by the initial test. Sensitivity is often used in defining performance of initial testing kits and refers to the relative detectability of the kit or device (of positive cases) in question over a comparison method. On the other hand, specificity refers to the percentage of negative results using the kit or device compared to the total number of negative specimens using a comparison method. The comparison method is usually a Gas Chromatography-Mass Spectrometry (GC-MS) or LC-MS method.
The required detection or quantification limit for drugs in oral fluid depend very much on the application and type of screening test employed. For example, in workplace applications the Substance Abuse & Mental Health Services Administration in the USA (SAMHSA) has recommended confirmation cut-offs for THC, cocaine, morphine and the amphetamines of 4, 8, 40, and 50 ng/mL, respectively.22 In contrast, the European Union roadside assessment testing study (ROSITA) for impaired drivers have recommended somewhat different cut-offs,22 as has the Australian Draft Standard for the collection, detection and quantification of drugs of abuse in oral fluid.85 (Table 3)
The variable target minimum concentrations probably reflect the relative embryonic stage of drug testing compared to urine drugs of abuse testing. It is possible that some international agreement may exist in the future regarding minimum detectable concentrations (or cut-offs). However, this is unlikely since there are still significant differences in cutoffs in urine between countries after over 30 years of testing. Moreover, inadvertent exposure may limit the concentrations that can be used to prove deliberate use. In the case of cannabis, a study has found THC concentrations for a short period following high passive exposure in an unventilated room of up to 26 ng/mL.86 Ingestion of poppy seeds in food can cause a positive test result for morphine and exceed the 40 ng/mL SAMHSA cut-off for about one hour following consumption.87
Cocaine should not be used by nursing mothers or smoked (such as with "crack") by anyone in the vicinity of infants because the infants can be exposed by inhaling the smoke.[3,4] Other factors to consider are the possibility of positive urine tests in breastfed infants which might have legal implications, and the possibility of other harmful contaminants in street drugs. A breastfeeding abstinence period of 24 hours has been suggested for women who occasionally use cocaine while breastfeeding, based on the rapid elimination of cocaine by the mother.[5] Some authors have proposed that breastfeeding be discontinued only for those infants who test positive for cocaine exposure.[6] However, the Academy of Breastfeeding Medicine suggests that women who have abused cocaine generally should not breastfeed unless they have a negative maternal urine toxicology at delivery, have been abstinent for at least 90 days, are in a substance abuse treatment program and plan to continue it in the postpartum period, have the approval of their substance abuse counselor, have been engaged and compliant in their prenatal care, and have no other contraindications to breastfeeding.[7]
A woman who admitted to 2 years of cocaine and cannabis use provided breastmilk sample 24 hours after delivery. She denied use of any drugs of abuse in the previous few days, although her urine was positive for cannabinoids and cocaine metabolites. Her breastmilk contained 138 mcg/L. Neither norcocaine nor cocaethylene were detectable in breastmilk.[12]
The mother of an 11-day-old infant applied cocaine powder to her nipples for pain relief. She then breastfed her infant using a breast shield that allowed protrusion of her nipples. Three hours later, she found the infant gasping, choking and blue. On arrival at the emergency room, the infant was ashen and cyanotic. He had hypertension, tachycardia, shallow breathing, hypothermia and was in status epilepticus. Seizures resolved in a few hours after treatment and the infant was discharged at 16 days of age with no apparent sequelae.[15] Although the infant's cocaine exposure was not via the drug in breastmilk, it illustrates the extreme risk of exposure of young infants to cocaine.
If you need to pass a drug test on short notice, the first thing you should know is that testing technology has advanced to the point where classic ways to fake a test, like putting some salt in your urine sample or using fake pee, are mostly detectable. Your best bet is to prepare your body as far in advance as possible by stopping drug use as soon as you find out you need to take the test. When there's not enough time to flush traces of drugs from your body, there are last-ditch techniques you can try to thwart the system. Keep reading to learn the best ways to deal with a drug test on short notice and the essential to-do's for the morning or night before your drug test. 2b1af7f3a8
