most companies in the US have tested for at least the last 20 years. typically just a piss test, though my current employer took full hair and blood samples. in fact, maybe I should blame them for my male-pattern baldness.
that said, I do not believe we test new hires here in Europe. not because we don't want to, but most European countries (Switzerland included though not to the same extent as Germany or the Netherlands) are very employee-friendly and the data privacy issues on this side of the pond are quite tricky.
