2 reasons I am worried.

1) For the past 4 days before the urine test, I had not taken my prescribed dose of Oxydodone and Hydrocodone. I am prescribed to take 2 hydrocodones per day and 1 Oxycodone per day. 4 days ago I run out of hydro completely and had only 4 left of oxy. Therefore I was taking half oxy every night to make it last. I am afraid that I won't have sufficient trace of both drugs on that test. Should I be concerned about this?

2) I smoked a little bit of marihuana about 1 week ago. I mean, I had about 5 hits of a pipe. Previously to this I smoked heavily for about a week at my friend's house.. that was about 1 month ago.

What should I expect to happen next time I visit? Or is my doctor going to call me before I make my next appointment to tell me about his findings? Will he make me come in to humiliate me and tell me he can't treat me anymore? will he keep treating me but will give me a warning or regular tests to see if I keep smoking? will he tell my primary care doctor about the THC that more likely will appear on the test? If he denies me future treatment, will I be able to go to another PM clinic or I my doc will have to tell when the new doc requests medical records? Sorry for all the questions but I am really worried. This is the first time I have been on PM and totally forgot about the random tests.
Any advise will be appreciated!
