Very long half-life: Klonopin (clonazepam) has a very long elimination half-life: 18-60 hours. It takes 5 of these half-lives to effectively eliminate the Klonopin (clonazepam) from your system (supposing you're not still taking it). So depending on your metabolism this could take 12-14 days. If you're still taking a few of the pills, this would also register positive.
