Nope. You'll hurt your back if your bars are not correctly positioned. But, if you are in good shape and sufficiently flexible (and I'm not talking Romanian gymnast flexibility here), you should be able comfortably to ride in the drops for long stretches. I've ridden for two hours in the drops into a headwind without any problems.
