Several factors can affect how long crack is detectable in urine. Different forms of drug tests also have different detection windows, so it's no simple matter to determine if you're likely to pass a drug test. Here's some advice to help you decide if it's safe to take a drug test, as well as what to do to avoid failing one
Crack and drug tests
Crack is just a crystalized form of cocaine, so it inevitably shows up on the cocaine panel of a NIDA-approved 5-panel drug test. This is the most basic of all drug tests, so if there are enough cocaine metabolites in your urine, you will fail the test.
This can have drastic consequences, such as by hindering your promotion chances, getting you referred for treatment, or even losing your job.
So, how long is crack detectable in urine?
As mentioned earlier, there are a few factors at play here. To keep things simple, we'll focus on urine drug tests for now. First, your level of use will affect the detection period. Crack is generally purer than powdered cocaine, and because it's smoked, more of the chemical gets into your system than if you just were to take a bump of coke. While cocaine is quickly metabolized by the body, most drug tests look for the metabolite beonzoylecgonine, which persists for much longer.
Crack isn't usually the occasional user's drug of choice, but if this is the case, you could possibly fail a drug test in the 2-5 days after last using it. Chronic users will have a much harder time passing a drug test, and it may take around 10 days of complete abstinence before they can safely take one.
There is also an exception for people with certain kidney disorders, because they can also fail a drug test up to 10 days later, even if they were just occasional users.
Embarking on a 7-day detox program can help the process, but it's always best to test yourself before a real drug test.
What if you still fail a home test?
If you pass your home drug test, well done. You can now confidently take a real drug test.
If you don't pass, you do not need to worry quite yet. A two-stage detox kit can still get you through your drug test. There's also a more potent version available for those with larger bodies.
What about saliva and hair drug tests?
Saliva testing devices seem to vary considerably in their detection times, with there being some reports of them detecting crack use up to 10 days later. To be safe, you could use a special detox mouthwash just before going to your drug test.
In terms of detection time, hair drug tests present the greatest danger to someone who has recently stopped using crack. These tests detect drug use over the past 90 days by analyzing the hair growth from that period. Instead of shaving all your hair off, including all body hair, you could invest in a detox shampoo to use on the day of your test.
