Look for a job with a small to medium size business, they are less likely to drug test than a big-name corporation.

It wouldn't hurt to make a call, but I doubt HR would release accurate information. I'm learning working in the field, that what they say, and what they do are two different things!

Plus in most company handbooks, most companies say they do random testing, perhaps they do, perhaps they don't, but only those employees on a need-to-know basis have that kind of information.
