Well, I guess I don't believe this theory. The pargraph below is from this site. It's pretty technical, but it is clear that the development of drug tests was in the early stages in 1972. Of course, they could be just as stupid about drug tests as they are about word processing.

In 1972, Rubenstein and his co-workers published the first details of a "homogenous enzyme immunoassay." Others labeled it an enzyme multiplied immunological technique, hence the acronym EMIT®, which is a trademark of the Syva Corporation.

You don't believe it because you are a Republican (ie, intellectually honest, logical, fact based). The cocaine story is not meant to sway reasoned voters. It is meant to depress the base and the uninformed. Based on what I've read on other threads, I think it is absolutely provable that Bush wouldn't have been subject to a drug test during his physical in 1973, but I doubt that CBS was planning on analyzing the story from that angle.

But were they done routinely (with the physicals) in the military? My retired USCG hubby says no, not until the 80's.
