If you are worried about how you do pass a drug test if you have taken Adderall, well you can breathe easier. Adderall does not stay present in the body for more than 24 hours, regardless of who you are. Another thing to consider is the fact that you can also tell the person administering the test that you are on a prescribed medication that could alter the test results. Allowances for this kind of thing are made often.
