Anybody ever been drug tested for handling sensitive data?

I am currently a DA for a company that uses data sets from clients with PII. The client I was assigned requires all people handling their data to take a drug test. I happen to smoke a lot of weed. I’m debating trying to cheat the test or just coming clean to my boss and asking to get taken off the assignment.

I never thought this was a possibility and wanted to know if this is common for jobs handling …
