They're for suckers (6)

I believe the answer is:

straws

(Other definitions for straws that I've seen before include "Thin tubes to suck up liquid" , "In the wind, they are signs or portents" , "are drawn thusto drink!" , "Dried stalks used as fodder or bedding" , "Thin plastic or paper tubes" .)

I've seen this clue in The New York Times.
