The next time you hurredly sign for your next financial aid package, read the fine print about being responsible enough while getting aid, not to do drugs. There's a reason they include that little clause. The underwriters want you to be sober enough to graduate and repay your aid through income taxes--so the next schmuck like you can receive aid too.
But I'm sure you are perfectly okay with denying student aid to a guy caught with a joint while allowing it to a convicted rapist.
There have been enough horror stories arising from this rigid law then can be counted. This law is ideological legislation, there is no solid actuarial support for the provisions in the law.
