How long does Adderall stay in your system or urine for a drug test? This question is sometimes made by users that are subject to tests for their job or probation.

Prescription Adderall comes in immediate release tablets or capsules and extended release form. There is a  big difference in the time Adderall stays in your system, urine between the two.

The answer to this question varies for any specific individual, based primarily on body weight and how much Adderall was taken. Adderall detection  in body fluids is primarily dependent on:

  • body weight
  • metabolization rate
  • amount ingested
  • how long taking it

There are general guidelines that will prove true most of the time. Whether this amphetamine can be detected by a drug test depends on the type of test.

How Long Does Adderall Stay in Your Blood or Urine?

Adderall is detectable in the blood stream for a different amount of time than it is in urine. Immediate release Adderall can be detected in urine for about 48 to 72 hours. Extended release could remain in the blood for up to four days, or approximately 96 hours.

How Long is Adderall Detectable in System?

Amphetamines are detectable in the urine for at least 2 to 3 days (48 to 72 hours). This can vary with dosage, weight, and diet, which means a good conservative rule of thumb is they are detectable for up to four days. For heavy Adderall users, increase the amount of time.

Half-Life Biometrics

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. 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.

Blood Tests

  • For occasional users, blood tests usually are unable to detect amphetamines after approximately one day.
  • Heavy users systems need more time to metabolize all of it

How To Avoid Positive Drug Tests

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.


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.
