Option "B"
Smoke something very subtle (on this end, Union Square) as a "try" tobac. That way you can taste exactly what's left over from the last guy and how strong/persistent it's likely to be.
As long as it's not full of Lakeland Urinal Cake Perfume, the second & third bowls will give you a handle on whether (& how fast if so) it will recede. This, in turn, gives you a handle on whether the best long-term solution would be to send it off to Walker Briar Works for an Ozone de-tox that will let you start over again from square one in it. $5 + postage both ways + hassle + wait can still be way preferable to long-term annoyance.
FWIW
