Is it possible to test negative for Klonopin on a benzo test?

Absolutely not. Klonopin is a Benzodiazipen and it can stay in your system for up to 6 weeks based on your usage and your metabolism. I have had it test positive for 5 weeks. Benzo's are nearly impossible to cleanse out of your system. I even bought a 70 dollar test cleaner and I still failed.
