Got a question i hope someone can answer...

Been smoking some pretty stoney herb lately that i'm pretty happy with, but have noticed one odd effect that i haven't experienced before. When i smoke, my lungs feel like i've recently taken a bunch of antihistimines--all dry, not the usual phlegmy kinda congestion, but the opposite in fact.

The herb smells/looks fine and produces no other odd effects.

Is there some kind of pesticide or herbicide or other substance used that anyone knows of that can cause this effect? I've been smoking regularly for a long time and this is a first for me.

thanks
