I am a 21yr old female, I weigh about 135-140 with a Regular metabolism I took 20mg instant release adderall at 2pm Tuesday afternoon, another 10mg at about 8pm Tuesday and another 10mg at 6am Wednesday morning I was drug tested about 8pm Monday night so about 132 hrs after I took the last 10mg will I fail??
This question has also been asked and answered here: How long does adderall stay in your system?
If the adderall is prescribed, you can show your employeers your vial and you'll have no problems, but if it's not prescribed I'm afraid you may be in trouble with your drug test. If you never take any rx meds that are not prescribed to you, you will never need to worry about this problem.
The half life of Adderall is about 10 hours.
This means that every 10 hours, half of the previous amount of Adderall in the body disappears.
For example, if you took 10mg of Adderall at 12AM (midnight), at 10AM 5mg of Adderall will be left in your body. At 8PM, 2.5mg will be left, and so forth until there is 0mg left in your body.
As a rough guide it takes about 5.5 half lives for a drug to be out of your system. For adderall then it would take just over 2 days for a dose to be out of your system.
(5.5 x 10 = 55 hours - which is just over 2 days)
You should allow for longer (7 days) if you have taken adderall frequently and at high doses
