I believe in random drug testing to see if the recipient needs further help. Maybe the reason they are on welfare is because of some form of dependency that is holding them back from seeking a career. This should align with common sense laws. For example the recipient may have a mental or physical condition that needs to be addressed. This in no way means to be used as a punitive method for incarceration but just the opposite to determine the needs of the citizen for their own betterment and betterment of the government subsidy.
