Yeap. A chemically taste normally means it hasnt been flushed at all, or properly. You'll find this with hydroponicly grown bud more than soil grown, but it happens with both. This is what happens when growers just want to get their product out as quick as they can so they can make a bigger turnover. Water curing will do the trick.

Although, uncured bud [normal dry curing] will have a horrible taste too - very planty and all in all - CRAP.
