How can you test positive from a urine test for cocaine when you don't use it It has been a month and 3 urine tests later I was drugged by an unknown substance at a wedding right before my first test?

You either would have taken it voluntarily or someone slipped it into something you were smoking (like a joint.) Urine tests don't lie. Bars and wild parties are notorious for 'date rape drugs' as well as slipping other drugs into drinks, getting the person so drunk they are talked into snorting cocaine, or, the person taking it is in denial.
