Yes, curing will make the smoke much smoother, smell much better, and the taste of the herb will come through in the smoke. Some say it increases potency via decarboxylation, but I am not 100% sure about that. Also, it's possible that the high is cleaner, too, since curing also breaks down chlorophyll, so you aren't smoking as much of that. Some also say it allows for the high to be longer, too.
