Adderall (amphetamine) is a prescription drug that can stay in the system for anywhere from one to 90 days, depending on how a person is screened for Adderall use.
Adderall use can be detected by testing a sample of urine, blood, saliva, or hair. The amount of time Adderall remains detectable in these specimens varies.
On average, Adderall use can be detected for one to four days after last use. Hair follicles are the exception. Hair samples can contain traces of Adderall for up to 90 days after your last dose.

The amount of Adderall you take can affect how long it stays in your system. Higher doses may take longer for the body to fully process.

The rate of your metabolism can affect how long it takes for your body to fully process Adderall. Typically, people who are older or have poor health will metabolize Adderall more slowly.
Liver And Kidney Function
The liver and kidneys have an important role to play in drug metabolism. Having impaired liver or kidney function may affect how long it takes for the body to process Adderall.
Using Multiple Drugs
Taking Adderall with other drugs, including alcohol, may affect how long it takes for the body to absorb and metabolize Adderall.
