Regardless of how easy/hard, with the testing now in place, it just doesn't pay to take the risk. I know that each player on my son's college team have already been tested at least once, some twice and 1-2 have been randomly tested 3 times.
They take it very seriously. Whether or not it used to be easily obtainable, it's virtually disappeared from a lot of campuses.
Others, I can't speak for.
