How long does meth stay in your system?

It depends: It depends on your metabolism, but meth is generally detectable in urine for 1-4 days after use. Urine drug tests are the ones most often used. Meth can also stay in your hair for up to 90 days, though. It's an extremely dangerous drug, and best not to use it at all. ...Read more

Which "meth???": Methamphetamine is a short-acting drug, but it has longer acting metabolites which are what are measured in urine. After a single dose, it's half-life is about 4 hours, but metabolites can be found for 2-3 days. After regular heavy use, it can be detected for 5-7 days. Methadone (also called meth) lasts for 3-5 days, and in long-term use metabolites can be detected for weeks. ...Read more

Here's what to do: Kara, you've lost the ability to control your addiction, knowing you have a test that using today will cause you to fail, and planning to use anyway. Phone your counselor, acknowledge that you're helpless, and SAVE YOUR LIFE. Not everything people have told you is true, but the meth warnings mostly are true. The dead meth uses I've autopsied HAVE ripped up their flesh. Don't die like that. ...Read more

Only several days: Even in very heavy long-term users, methamphetamine and its metabolites are relatively short-acting, and will give positive urine drug test for 3-4 days at most. False positives for amphetamines, however, are very common, and may show up + with virtually any medication used for colds - sudafed, ephedrine, phenylephrine and others. Confirmatory tests, however, should be negative. ...Read more

Please stop, Jason: This isn't the place to ask about how to beat a drug test. You can't. You're still a young man, Jason. Meth will ruin your life and your using will hurt everybody that you love. Meth-heads that I've autopsied rip the flesh from their bones before they die. Please pick up the phone for your physician or someone else who can help you find a support group and stop. ...Read more

10 days or less: For most individuals having used the substance, the general consensus is often noted as a maximum of 10 days that methamphetamine remains detectable via a urine drug test. Often it is more like 3-5 days. The urine test rarely gives an incorrect finding if meth is in there. It can be detected in hair for much much longer. Meth is highly addictive, dangerous & harmful to mental and physical health. ...Read more

Please tell doctor: Please tell your doctor you're using meth, and get help. You're risking your own health plus the health of your baby. You may wonder whether meth will show in your baby when born, but the real problem is that any maternal meth abuse is associated with premature birth, growth retardation, & long-term learning problems in children. http://www.crystalmethaddiction.org/meth_and_pregnancy.htm. ...Read more
