Yes

Its a waste of time, resources and money. There are already laws that exist to criminalize purchase and use of drugs. That's satisfactory already. What someone does with their own body is no one's business so long as it doesn't harm or impede on others.

Some drugs can be helpful to some but it might be illegal in the work space, which puts them in a bind.

To test each person who is on welfare for drugs would require our nation to mobilize a committee of people willing to force this service upon people. I believe most people who were on drugs in this scenario would refuse creating a difficult and unrewarding job that would result in an improperly implemented program. If the program did work I still believe that Welfare qualifications should focus on ability to provide work and perhaps keep a family safe. If someone happens to take a recreational drug during this I don’t believe it’s worth pulling Medicare. Once marijuana is legalized however, then maybe this law could see some development.
