How Long Does Adderall Stay In Your Blood?

Medically Reviewed by Johnelle Smith, M.D. on April 30, 2021

Adderall can take anywhere from 12 to 24 hours after your last dose to leave the bloodstream. This timeframe can vary based on several factors, including the formulation taken, dosage, and other personal factors.

How Long Can Adderall Be Detected In Your Blood?

Adderall enters and leaves the bloodstream fairly quickly. This makes a blood test non-ideal for detecting Adderall use, unless it’s used specifically for urgent or emergency purposes.

Detecting Adderall In The Blood

Adderall (amphetamine) is a prescription ADHD medication. It can stay in your blood for anywhere from 12 to 24 hours after your last dose.

What Factors Can Affect Adderall Detection Time In Blood?

Not all bodies metabolize drugs like Adderall at the same rate. The actual time-frame for how long Adderall stays in the blood will depend on a variety of factors.


High doses of Adderall can take longer to absorb and metabolize compared to smaller doses. This also applies if you take multiple doses within a short window of time.


Adderall comes in immediate-release and extended-release forms. Extended-release forms may stay in the blood longer.

Frequency Of Use

Taking Adderall very often for a long time may cause a buildup in the body. This can result in a longer detection window.

Body Composition

High body fat percentage is associated with slower drug absorption, meaning it may stay in the body longer.

Polydrug Use

Taking multiple drugs, including alcohol, can affect the amount of time it takes the body to process Adderall. This can include the use of other prescription drugs.

Metabolic Rate

Metabolic rate—that is, the speed of your metabolism—can affect how long a drug will stay in your system.

Why Test For Adderall Abuse And Addiction

Drug testing may be ordered if a doctor suspects that a person is abusing Adderall. Tests can also be ordered by legal entities, employers, and sports organizations.
