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.
If one's intention were to find another benzodiazepine that has a LONGER half-life than Klonopin, then Valium/diazepam is your best bet. It has a half-life of up to 100 hours, by most literature I've seen; double that of Klonopin.
