Are you smoking aros? A lot of aromatics will smoke wet regardless of how you prep it. J.T. is correct it is condensation,itís typically a sign of overly moist tobacco, it will also happen if your smoking to hot or the bowl might be packed to tight, maybe try drying your tobacco a bit more and slow down your cadence.
If I see a stick that made a noob nic sick,I put it on my list as a must try. (UBC03)
