I've been on klonopin for sleep and prescribed xanax or ativan for acute anxiety at a couple points over the years, and never had any trouble getting off them. I usually stayed at the lowest dose and often skipped doses, and I'm searching my brain for any memories of withdrawal symptoms, and I don't remember ever having any.
I would bet that more patients have my experience with these drugs than have the long term addiction and severe withdrawal, and doctors have often passed people on before the consequences start stacking up.
I still think they should be prescribed extremely sparingly, because even in my experience with them, they didn't really do too much that some running and yoga didn't do, and they come with much bigger risks.
