I am prescribed 20mg. Of Adderall 3 x a day, have been for about two years, this helps me with my MS. I went to Dr. Office to pick up prescription they said I needed to take a urine test to check for THC. I said sure, then they said well it s Friday and lab closed at 12:30 on Fridays, so call Monday to schedule a urine test. I called Monday and they said the dr hasn t put the order in yet. We will call you when he puts the order in and you can just stop in. Long story short it took them eight days to schedule the test. I passed my test for THC., witch I new I would, but now he says you had no Adderall found in system., I then replyed why would there be I have not had any in my system for 8 days before test!!!!! Then the nurse said ohh well I ll see what he will say because he won t prescribe you your Adderall!! I waited for 4 more days for answer only to get, when did you get your last scriped filled and where I got the bottle gave him all the info, that was on Jan. 16th 2015 this is now March 2nd !!! I am feeling like some criminal, and I have MS!!!!!! Would the Adderall be out of my system after 8 days?
