PS it’s only if they give me a drug test.

Context? While I appreciate the energy, this isn’t the way to do it. Saying “im going to have to fail this for weed” and “totally” in a professional letter about why you should be exempt from drug testing is a good way to get a job for the next guy in line. You also say “photos” but I only see one on the page?

There’s no reason to make an appeal to emotion here. Type a short response like:

I am willing to take any drug test but in the interest of full transparency, I use doctor-perscribed cannabinoids. This is to treat a health concern and it has no impact on my work.

Good luck DaddysLittleSlut!
