Its illegal and legal by law, the law works in both ways. Its officially tolerated by law, which allows me to smoke while walking down the street. Therefore employers usely don�??t do drugtest, doing a drug test is actually the same as doing an alcohol test during a test interview: its not even thought off.

I had many job interviews and never had to do any test, people expect you to work in a clear state of mind not being drunk nor stoned.
