I took maybe 6 40mg vyvanse and 2 10mg adderal during midterms the last two weeks of October. No other drugs. No "study" drugs since oct 31. I have a psychmedics hair test next week. That will be 72 days drug free. Do you think I will fail for amphetamines?

Detection at low levels may be what you expect, but without knowing what the acceptable level to pass is, or any other factors that may be relevant, that's only a guess. Did you have a prescription for these drugs or were they bootlegged?

Is this your first test?

I got them from a friend. No prescription. It's a pre employment test. It's through physicmedics but I cannot find much about the cutoff level. It is my first test.

Do you think it'll be high enough concentration to fail?

If Psychmedics uses the same methods of hair drug testing that the lab (Omega) I use does neither the vyvance or adderal will show up on a hair drug test. Also, a hair drug test is meant to show consistent use over time and from your posting it looks like you didn't do enough for it to show up in a hair drug test anyway. The cutoff level for amphetamines for my hair drug test is 500 pg/mg. I don't think I would lose any sleep over it.
