"abuse money by buying drugs" In what way is that abusing money? People buy beer and cigarettes all the time. They spend money on tattoos, which by all arguments can be just as addictive and are technically just as useless as recreational drugs . You yourself appear to have piercings which I would argue are just as big of a waste of money as any drug someone might do. You can't argue that they add to your quality of life in any significant way. They don't cure cancer, put food on the table, or pay for that college you are trying to save up for. They are just something you got because you thought they were cool. What a person does in their free time does not necessarily effect what they do at work. If the "known drug addicts" are doing their jobs and doing them correctly, you have no place to speak about whether they should have that job or not. You are no more deserving of a job than anyone else who wants to and actually does work. This is especially true if the person hired over you is older with more experience in the field.

I don't know how it is in America, but here in Australia, a lot of places look down on tattoos and piercings even though it is discrimination. What someone does in their private life that doesn't affect their ability to work, doesn't matter to the company. How a person looks on a day to day basis at work, apparently does. And by the way, I smoke pot and I work full time and study. So not every person who uses drugs doesn't deserve to work.
