Hello,

The half life of Adderall is near 10-20 hours so it should be completely out of symptoms after 48-72 hours after last dose.

Adderall shows up positive on a drug test for amphetamine however not for methamphetamine.

If you have valid prescription for Adderall then usually it's not a problem

If a test shows for Amphetamine then Medical Review office 'll discuss with you and needs prescription.

If you test positive for meth then further testing including GC/MS should be done for confirmatory results.

If you have any further query then we can discuss it thoroughly rather than give us poor/bad service.
We are here to help you until you satisfy.

Bonus and positive feedback are highly appreciated.
Thanks.

but after I show a false positive even if I have a prescription will they be able to tell I took more than the recommended 15 mg dose ?
Expert:  Dr. Anil replied 1 year ago.

Hello,

As you have taken extra doses of Adderall that were larger (5 times what you were prescribed), then that might be detected, the variation (based on time from last dose, intake of water, metabolic rate etc) can alter the concentration of drug.

Hope this helps.

if I didn't take any for 48 hours before my test would my levels appear normal as if I just took my normal doses The day of the test
Expert:  Dr. Anil replied 1 year ago.

Hello,

As we have discussed earlier,higher the dose longer the detection time and higher the concentration of drug in urine.

If you took normal dose before test then chances of negative results are high after 48 hours.

Hope this helps.
