What would I add to the Constitution?
I would add to the constitution that to be able to get welfare you must get drug tested. I think that too many people are cheating the system and getting some money for free. If they have enough money to go get high and buy drugs then they have enough money to go buy some grocery's and stuff they need. Even though I am not old enough to pay into the taxes I think it's wrong in every way. They need to get there lazy butts a job ....... but they can't probably pass the drug test to get into the job.
