Do screenings for clinical trials test for cannabis?

Question

I recently got a job being tested for a phase 1 clinical trial for a lot of money.

I told them I have not taken any recreational drugs in the last few months which in retrospect is not exactly true.

Are they likely to test for cannabis in my screening

Answer 1

Probably so.  Cannabis' active ingredient is THC and it is one of the most commonly tested drugs in drug tests.   If you are a heavy user, it may remain in your system for some time.  If you just used it one or two times, you should be fine unless they do a hair test.
