Abstract: For a linear elliptic operator with a singular drift that satisfies a finite Carleson measure condition, we prove that there exist `ample' sawtooth domains of the unit ball $B(0,1)\subset \R^{n+1}$ so that a BMO solvability assumption in these sawtooth subdomains implies that the elliptic measure satisfies the weak $A_\infty$ condition with respect to the surface measure on this `ample' sawtooth domain. This is a quantifiable absolute continuity condition, which is equivalent to saying the $L^p$ Dirichlet problem is solvable for some $1
