How can you flush Klonopin in 24 hrs out of your system?

The short answer is: Stop taking the drug and wait. It'll be gone in a few days. The catch is that, like all benzodiazipam category drugs, if you've been taking it for more then a month then you'll need to taper off slowly because the withdrawal can actually be fatal, so if you're asking about reversing a habit, you should definitely consult with a doctor.
