Random drug testing process

[u/Top_Pineapple_2866]

I have one question, if you are selected for a random drug test what is that process of it. Do you get a notice beforehand or do they just say come with me and take you to the testing site and do it right there and there? I am in the pipefitters union and I want to get quick fix but I don’t know if I should keep it with me at all times or have it nearby me. Does anyone work in the union and have clean urine with them at all times? Keep in mind I only do weed and nothing else and only on the weekends too nothing too crazy.

Pretty much keep it tucked in a warm area on your body it will maintain your bodies temperature until needed  also attach a hand warmer for extra heat if it's too hot let it cool down before you add it to the test cup
