So, let's say two parents are working poor, and their kids get free school lunches and the family gets food stamps. Let's say dad goes fishing with his buddies one weekend and smokes some pot to relax and unwind from his daily grind.

The following week, he takes a test down at DSHS and tests positive.

Now the family loses their free school lunches and food stamps, so they use wages to buy food but can no longer afford to pay rent, and wind up living in dad's car.

Brilliant... The stupidity of such a law is immense. The lack of a thought process involved in the creation of such a law is stupider still.
