Public health in Toronto and Vancouver run a program where they do mass spectrometry on recreational drug samples submitted by the public. Even some community pharmacies are participating as drop-off sites. You put a few milligrams in a small vial and you get the results online. The service is free and anonymous. And not widely used. Even with some government and legal support, it's hard to convince people to test their drugs.
