I took about 4 10 mg valiums and 1 2mg Xanax (alprazolam) bar together for 4 days, same dose of meds each day. I have a drug test in 16 days. Will I pass or fail?

Pass. If you are not a chronic user and this was a one time thing, most likely you will pass. If you are taking the valium daily, it can stay in your system for up to 30 days. It is dangerous to take these two drugs together if this is not a prescription and under close supervision of a doctor. They work in the same way and can exacerbate the sedative effects. Please enter treatment if addiction.
