An individual's principles are just the same as a company's policies. You might feel better about yourself refusing a drug test but you might miss out on an otherwise good job. It may not be a problem for a small company but a larger company that has to hire lots of manual labor, where drugs and alcohol are definitely a problem, cannot treat you differently so they have to insist on the drug test. Current employers insisting on a drug test is definitely more problematic, though, if there's no reason to suspect a problem it seems unreasonable to insist.
