How Long Does Adderall Stay in Urine – (And Why)?

Exact Answer: 7 days

Adderall is becoming known worldwide for its potent effects. Composed mainly of a stimulant known as dextroamphetamine, Adderall increases sociability, reduces depression, increases the ability to focus as well as causing euphoria and insomnia. It was originally released as an ADHD medication but has been put to many other uses.

Adderall is highly popular with university students who use its “study drug” due to its ability to keep users awake and focused. It has also become popular with athletes as a performance-enhancing drug or as a recreational stimulant among drug users. As a consequence, most urine tests are now able to detect the presence of Adderall in urine depending upon how recently the drug has been consumed.
