I don't do anything special really....sometimes I may leave a little out in my grinder (leftovers from night before that I didn't get around to) and that gets regrinded for a VERY nice LB morning session.
The meds I get from my dispensary are usually very fresh...sticky and moist, but by no means 'wet'. If you are using 'wet' herb...well...you shouldn't be. I'll go straight home and try some out and I will get little vapor for the first hit maybe two hits, but the flavor is well, well worth it. Then by hit 3 and 4 the herbs are nice and dried out and she starts to chug!
The LB is a little bit harder and longer when using moist herbs. The grind is really key, and dry herb seems to 'pulverize' better for a nice, sand like grind.
