When does the drug trial for Immigration begin for the US.?

At what point in the Immigration approval process does the drug test happen? There is in a minute a vaccination requirement that one must have up to date so one might have to be in motion to the doctor. Does it happen when you go to the doctor or on a different date? Thank you
Answers:   
Drug test? If they do such a point, they get the results from your urine. That is on the day when you have to move about to the medical examination. It would be good if you didn't apply if you are a drug addict or drug broker. It would make our lives a lot better here since we don't need more drug addict. You know that's the reason why applications with a positive result get denied.
