Most benzo equivalency charts (not all of them agree) would tell you: 10 mg Valium = 2 mg Ativan = 1 mg Xanax = 0.5 mg Klonopin. I'd say most benzo charts are in error and overstate the potency of Klonopin, showing it to be twice as strong as it really is. I'm personally not a fan of Klonopin. I think it's so overrated, as it it's somehow magically better than other benzos.
