On January 1st, 2016, 22 states brought back the 3-month time limit that able-bodied adults without dependents can draw SNAP benefits, in addition to the 18 that already had them (mostly imposed 2013-2015).
About 45 million people are dependent on SNAP, and more than 500,000 could lose those benefits this year, with many losing them yesterday, April 1st, as they hit the 3-month limit.
