  The results of a sub-millimeter survey of SDSS broad CIV absorption line
quasars is discussed. It is found that the sub-millimeter flux distribution of
BAL quasars is similar to that of non-BAL quasars. This is consistent with the
idea that all quasars contain broad absorption line regions, but only a
fraction of them are visible along our line-of-sight. The observations are
inconsistent with BAL quasars being observed at a special evolutionary epoch
co-inciding with a high star-formation rate and dust mass.
