Same reason businesses can do it, to ensure that the people recieving it aren't on drugs.
It's to prevent the welfare system from being used to support drug habbits, especially the ones that feed the cartels. It's protection of assets
Probable cause means they have reason to suspect you of being on illegal drugs. It doesn't mean you just have to have a reason for wanting to screen people.
Given that the ACLU page I posted states that "according to a 1996 study by the National Institute of Alcohol Abuse and Alcoholism, differences between the proportion of welfare and non-welfare recipients using illegal drugs are statistically insignificant," there is no probable cause to suspect welfare recipients more than anyone else of using drugs.
