Native American History. Native American cultures in the United States include a wide array of socially and geographically diverse groups, whose nomadic ancestors are believed to have traveled via a long-gone land bridge across the Bering Strait at least 13,000 years ago.
A: Klonopin (clonazepam) is a benzodiazepine that is used to treat anxiety and panic disorders. According to the package insert, it has a half-life of 30-40 hours. The half-life represents the time it takes the body to reduce the amount of clonazepam by half.
Ativan is a short acting benzodiazapine (valium, xanax, klonopin, restoril, are all benzos.) Ativan doesn't stay in your system for very long- although it does stay in your system longer than xanax, which leaves your body pretty rapidly. I'd say about 24-48 hours depending on how much Ativan you are taking.
