More than one of my clients that has entered the DWI DIVERT program in Houston, Harris County, Texas has asked me what type of drugs will they test for when they do get tested. I must admit that I treat this is a loaded question. The truth is that I do not have an exhaustive list of all the drugs that will show up in a person's urine after they are tested. Nevertheless, what I tell my clients after any DWI in Houston is make sure that you have a prescription for any drug that may show up if you are tested for drugs.
In the past, I have had clients adamantly deny using an illegal drug despite the presence of it in their urine test. On a few occasions, the treating physician of the client has been able to explain why this may occur. Even though the doctor may have a valid explanation why this may be the case a judge still required the client to get a hair follicle test.
