Specifcally, Which Companies Test, and
Which Do Not?

There are too many companies to list in this document. An online searchable database called The Non-testers List 1 maintains a current list of companiesthat drug test and companies that do not.
The data contained in this list comes from reports by Internet users. So
if you have rst hand experience with a company, you should report it to
the list operator. If you are drug tested by a company that is not listed,
you can submit a report to the list operator, who will add it. If you have a
good experience with a company that does not violate your privacy, please
also report it to the list operator, who will provide good publicity for the
company.
The usenet Just-Say-No-To-Piss-Tests Project 2 used to maintain a similar
list of the drug testing policies of varies companies, but it has not been
updated since 1994.
