Can you crush suboxone in urine to show positive?

I assume you mean in order to indicate that you HAVE been using Vicodin?

If so, then no it wouldn't work. They don't test for the drug iteslf, they test for the metabolites that your body turns the drug into as it processes it. So if you put the original in the sample, even if its tested positive in the initial urinalysis, they would know somethings up because there would be no metabolites when they GC/MS'd it for comfirmation.

Just take even one half of a Vicodin, like a good 8 hours before the test. It is dectable after 2 hours of injestion, and doesn't become undetectable until 36-48hrs. So you're right in the window. If you have a test the next day, just pop one ore a half right before you go to bed.

Hope this helps,
