I would like to know how long does KLONOPIN stay in your system?
Do you mean so that you will show negative on a particular drug test, how long it is effective, the half life ???? Being more specific would get you a better response. The answer will depend on the amount you have taken, the frequency of repeated use, etc. Klonopin has a long half life ... 18-50 hours with the peak effects at about two hours. So it stays in your system longer than a fast acting benzo such as xanax where the half life is 6-12 hours. For drug tests you will continue to show positive for about three full days on a urine test or a week with blood tests. These answers are based on taking a single dose only.
