what shows up in a urine sample, but I'm under the impression that a week after being at the concert you described there shouldn't be any marijuana left in your system. Heck, even if you'd gotten stoned out of your mind, it should have all been metabolized before the week was up.

In any case, the doctor should be sharing with you the results of the drug test. Especially if he has any concerns about what you're ingesting recreationally, or outside of what he's prescribing.
