Methamphetamines generally show up on the amphetamines panel of a NIDA-approved 5-panel drug test, so any use can cause a problem for just about any sort of urine drug test. Of course, it won't stay in your body forever, but exactly how long does meth stay in urine for? Moreover, how can you still pass a drug test with meth in your urine?
So, how long does meth stay in urine for?
Methamphetamine is usually detectable in urine for three to five days after last use. This is somewhat longer than with regular amphetamines, which are only detectable for up to three days normally. There is also some suggestion that chronic users can fail up to a week after last using meth.
To speed this up, you could consider going on a weeklong detox program. In addition to providing supplements to support your body's natural detox process and help you relax, such a program will also help you to get into healthier lifestyle habits, such as eating well and exercising more. Keeping yourself well hydrated is another essential element of any good detox, but don't take this to extremes. There is no need to drink so much that you need to go to the washroom every 15 minutes.
How can you be sure you'll pass a drug test for meth?
The easiest way to be certain you will pass a drug test is to simply test yourself at home. If you're only concerned with meth, you can get a single-panel testing kit to save money. If you've also been exposed to other drugs, however, you may as well use a 5-panel testing kit.
These kits work in much the same way as the EMIT drug screening devices used by testing labs, so if you pass with these, you will almost certainly pass a real test. That said, you should try to replicate the conditions you would face in a real test. For example, toxin concentrations in your urine can vary depending on the time of day and your level of hydration.
If you fail a home test for meth, can you still pass a real test?
Even if you fail a home test for meth, there is a way you can still pass a real drug test. Detox drinks and detox pills can be taken about an hour or so before a urine drug test to send your urinary system into overdrive. While this does mean you will be peeing more than usual, it has the effect of cleansing your bladder for a short period. Any subsequent urine will then have drastically lower levels of meth in it.
Over time, the concentration of meth in your urine will return to normal, so it's essential to go to your drug test before this. You usually have a window of about four to five hours, but these products are usually most effective around two hours after using them.
If you have a large body mass, or if you've been a particularly heavy user, you should certainly go for one of the more potent detox drinks.
