David - I'm not sure what you are really trying to find out. If you are concerned about passing a urine screen it will depend on the sensitivity of the test used and you are not likely to find anyone who will volunteer that info. Klonopin has a half-life of up to 50 hours. That means that half of the active metabolite is still in the system after 50 hours, half of that half is still present after 100 hours and so on.

I have been taking Clonazepam for almost 7 years. I started by abusing it (unforunetaly). I have had MANY drug screens throughout the past 10 years and I have found the time Clonopin stays in a persons system varies GREATLY! It showed up in my urine for 4 weeks straight and I hadnt taken ANY in that 4 weeks, but I had taken it previous to that. I started using Clonazepam correctly about 6 1/2 years ago and I am SEVERLY hooked on the stuff! So I dont recommend it to ANYONE although I do KNOW that it DOES WORK for anxiety, depression, etc., My doctor is actually tapering me off it right now. The bad part is 1) I didnt ask for it. 2) Within the last 3 weeks I have gone from 3mgs/day to 1mg/day with Phenobarbitol at night which I am scared to take because it is yet just another addictive substance. I will never win! It all depends on how much you take, how often you take it, your weight, metabolism and the amount of water you can possibly drink without overdosing from that...So its a very hard question to answer and the only reason I am writing an answer is because I was wondering the same thing and thought I would share my experience(s). :) Good luck....
