I'm on a lot medications due to many medical issues. They include keppra, valium, Depakote, topomax, methadone, Ritalin and famitodine. I was recently sleeping in my vehicle at a rest stop and was given an oui. Even though I was not driving they told me I was doing illegal substances. is their a chance any of those medications could show up as something else? If not would they show up in my urine test ? thank you
