Interesting bill

A bill to amend title IV of the Social Security Act to require States to implement a drug testing program for applicants for and recipients of assistance under the Temporary Assistance for Needy Families (TANF) program. '
Bill # S.3361

So how are they going to police this? Wouldn't it require tons of man hours? I think it is a good idea, but I'm not sure they could actually make it work. Would a person have to drive to locations outside of their area just to get tested in order to get basic drugs for arthritis and stuff? How would California's medicinal marijuana program be affected. There seems to be more that needs to be outlined and worked on with this Bill. It would be nice to know that I am not paying for people to sell their Xanax on the street though.
