How Long Does Adderall® Stay in Your System? Urine, Blood, Saliva, and Hair Detection Times
Adderall® is a prescription stimulant commonly used to treat ADHD and narcolepsy. It contains mixed amphetamine salts, which increase dopamine and norepinephrine in the brain. Because Adderall® acts on the central nervous system, it is frequently tested for in drug screenings.
On average, Adderall® stays in your system for 2 to 4 days, but it may be detectable for significantly longer depending on dosage, metabolism, and type of drug test.
Adderall® Detection Times by Test Type
The following chart shows typical detection windows for Adderall®:
| Test Type | Detection Window |
|---|---|
| Urine | Up to 4 days (longer for chronic use) |
| Blood | Up to 24 hours |
| Saliva | 1 to 3 days |
| Hair | Up to 90 days |
These ranges depend on many individual factors, including metabolism and the type of Adderall® prescribed.
Adderall® Half Life: How the Drug Breaks Down
The half life of Adderall® is approximately 9 to 14 hours. This means it takes the body around half a day to eliminate half of the amount ingested. Total elimination usually requires several half lives, which is why Adderall® may be detectable for multiple days.
The half life may be longer for:
- People with slower metabolism
- Older adults
- Those with liver or kidney issues
- People who use Adderall® daily
Factors That Affect How Long Adderall® Stays in Your System
- Dosage: Higher doses last longer.
- Frequency: Daily users metabolize the drug more slowly.
- Body Fat: Amphetamines are partly fat soluble.
- Age and Health: Liver and kidney function impact clearance.
- Hydration: Concentrated urine increases detection.
- Type of Adderall®: Immediate release vs extended release.
Can You Fail a Drug Test While Taking Adderall®?
Yes. Adderall® contains amphetamine salts, which are detected as amphetamines on drug tests. Even when taken as prescribed, drug screens will typically show a positive result unless documentation is provided.
Immediate Release vs Extended Release Detection
Adderall® IR (Immediate Release) and Adderall® XR (Extended Release) have different clearance times.
- IR: Leaves the system more quickly.
- XR: Releases medication over several hours and stays detectable longer.
How Long Adderall® Lasts in the Body
- Effects last: 4 to 6 hours (IR) or 10 to 12 hours (XR)
- Detectable: Up to several days depending on test type
