  We couple the noncommutative Chern-Simons theory describing the fractional
quantum Hall effect to external magnetic and electric potentials, and derive
expressions for charge and current densities. To lowest non-trivial order the
density operator satisfies the commutator algebra characteristic of the lowest
Landau level. We take this as a strong indication that the theory correctly
describes point particles in a strong magnetic field. We also obtain the
correct QH response to a constant electric field, and density modulations in
response to a weak variable magnetic field.
