Klonopin's half-life is 18-50 hours. A drug leaves your system after 5 half-lives, thus, Klonopin should be out of your system in 2-3 days. However, half-life is affected by dose, as well, and 2mg is not a huge dose but it's a moderate one. It could take as long as 4 days to completely leave your system. It all depends on your metabolism, genetic makeup, body weight, and height.

I would say 2 mg is a big dosage for clonazepam seeing how the maximum dosage for a single pill is 3 mg I would say it’s a pretty big dosage
