I recently got a nice meerschaum purchased in Iraq from my brother ( Bacchus Head). I'm not sure if it's real meerschaum or not but it's a really nice pipe. Anyway, the first few times I smoked it there were no problems but now, for some reason, when I draw on it there's a bubbling sound like I'm smoking from a hookah or a bong. I've never dealt with this before but I've never smoked a meerschaum either. Pipes are pretty simple mechanically though so I can't believe the fact that it's meerschaum could have any bearing on this. Thanks.
