A member asked:

How much time does klonopin (clonazepam) stay in your system?

A doctor has provided 1 answer

20 hour half-life: Klonopin (clonazepam) is one of the longer acting benzos, lasting 20hours. So twice day dosing is usually sufficient. If you are abusing it and hoping to avoid a positive drug test, if might show up in your urine up to 5 days (5- half-lives to clear any medication)
