To pass a drug test with Adderall there are a few methods one can take. The real question is …
How much time do you have before the drug test?
Detection usually occurs between one to three days after amphetamine (Adderall) is taken. Amphetamine is significantly excreted in the urine. The amount excreted is heavily dependent on your urinary pH. There are various methods to pass a drug test with Adderall. One popular method includes trying to quickly get all of the amphetamine out of your system before the test (lower your urinary pH) or to reduce the amount excreted in the urine by greatly increase your urinary pH (by ingesting sodium bicarbonate aka Alka-Seltzer or Baking Soda).
Pass a Drug Test With Adderall
The amount of Adderall you consumed will be a factor in terms of passing a test. There was a study done in 1998 that tested seven healthy male volunteers by giving them an oral does of 5mg, 10mg, or 20mg. Then their urine was collected at 2, 4, 8, 12, 18, and 24 hours post dose.

Increase Excretion of Adderall (Amphetamine) via acidification of your urine
Take ammonium chloride 500 mg orally every 4 hours. This is the approved practice for treating amphetamine toxicity (when people overdose on Adderall or Meth).

Where’s the proof?
Urinary acidifying agents (ammonium chloride, sodium acid phosphate, etc.) increase concentration of the ionized species of the amphetamine molecule, thereby increasing urinary excretion.
Less than three days
You’re only hope is to either get it all out or decrease the amount excreted in the urine
More than three days
You are probably in the clear
