What Causes Positive Drug Test For Marijuana Even When Not Taken Any?

default
Posted on Mon, 22 Dec 2014
Question: Hi, My name is XXXXXXX XXXXXXX YYYY@YYYY , I'm not ashamed of identity. I take morphine sulfate regularly for pain associated from a severe accident that happened in 1996. I fell from a roof and broke my back. Now I have metal braces like you would not believe all along my spine. My doctor prescribed this years ago with fentanyl patches every two days. Now I'm in another situation that requires an alcohol treatment program with U As at random. I don't mind except two weeks ago one showed up positive for Pot or THC. They say this is not possible---- I have never smoked pot in my life-- What now?

Brief Answer:
Go for a repeat blood test

Detailed Answer:
Hello

I have read your query and tried to understand your problem. But I want to clear a few points so that I can answer your query in a better way.
1. What advice do you actually want? Is it regarding your alcohol dependence treatment? Or reasons for THC positivity. If it is the later it would be very difficult to predict the reason since there are many variables involved.
2. Do you still use morphine/fentanyl?
3. Why do the doctors want to repeat entire course? Is it because you were tested positive for pot?

I request to please answer these questions. The more straight-forward you put your problems, the better I would be able to help you.

Thanks.

Yes I still take fentanyl 100 mcg/hr every 48 hours and morphine sulfate 15g
As needed for pain.
I received a DUII a year ago and am in a drug treatment co. For alcohol and drugs.
At the very last DAY and about a dozen random UA tests ok the last one came out positive for THC.
How is this.possible when I have never smoked pot in my life????
Yes my doctor prescribed everything and am seeing him today.

What should I do???

Detailed Answer:
Thanks for a gollow-up query.

Sorry for the late response.

If you have never consumed pot, this might be a testing error. You can ask for a repeat test.
And also, the de-addiction management for pot and alcohol are different. I don't think there is any need to go for a complete deaddiction program again.
But the first thing would be to go for a repeat test for THC. Since you have never consumed, it should not test positive.

Hope this help you.
Thanks.
