Determining How Long Does Adderall Stay in Your System & Urine For a Drug Test

A question Adderall users may often ask is how long does Adderall stay in your system urine for a test. This question is usually made by users that are subject to drug tests for their job or users of Adderall who are also on probation. The answer to this question varies for any specific individual, based primarily on body weight and how much Adderall was taken. There are general guidelines that will prove true more often than not.

How Long Does Adderall Stay in Your System?

Prescription Adderall comes in immediate release tablets or capsules and extended release form. Immediate release Adderall can be detected in urine for about 48 to 72 hours while extended release could remain in the body for up to four days, or 96 hours. How long Adderall stays detectable in body fluids is also dependent on a person’s weight and metabolism.

Average Length of Time Adderall Stays in Your Urine System For a Drug Test

Asking how long Adderall will stay in your urine system is a tad too unspecific, because there are two different answers to that question. Adderall, or more specifically the dextroamphetamine that is found in Adderall, is detectable in the blood stream for a different amount of time than it is in urine.

For a urine test, you will usually test positive for an amphetamine roughly 2-3 days. This can vary with dosage, weight, and diet, which means a good conservative rule of thumb is that it is detectable for up to four days. If you are a heavy user, increase the time.

Blood tests are not able to detect amphetamines as well as urine tests.

Computing Exactly How Long Adderall Stays in Your System Urine For a Test

Adderall, Dextroamphetamine, has a half life of approximately 10 hours. This means that after 10 hours, the amount of dextroamphetamine in your body is half what it previously was. Thus, if you took 30 mg of Adderall, 10 hours later 15 mg will be in your body. Ten hours after that it will be down to roughly 7.5 mg. And ten hours after that it will be down to roughly 3.75 mg.

Whether this amphetamine can be detected by a drug test depends highly on the type of test. A urine test is able to detect lower amounts of the substance in your body than a blood test can.

For occasional users, blood tests usually are unable to detect any trace levels of amphetamines after approximately one day. Again, for heavy users, probably more time is needed. 

Ways to Avoid a Positive Drug Test

If you are a drug addict who simply slipped once, or took Adderall for a legitimate reason, there are ways to avoid testing positive. The best method is time. If you can schedule your drug test for a later day, you are more likely to come up clean. Also, as previously noted, if you have the option of a blood test or a urine test, the former is less likely to show amphetamine usage after a day.

Finally, amphetamines are water soluble, which means that you can literally sweat them out of your body. If you are concerned about a drug test, you can drink lots of water and engage in heavy physical activity. This won’t clear your system completely, but it will help speed the removal of amphetamines from your system.

Treatment For Adderall Abuse

While it is important not to let a single drug test ruin your life, it is also important to be drug free. Even if you do manage to pass a drug test, if you have an Adderall addiction, you should seek assistance to end the addiction as quickly as possible.
