Can a person get a get a dirty urine from someone else smoking crack cocaine in the same room?

If you inhale enough smoke it will get into your system. Are you sitting literally ontop of the person and inhaling from the same crack pipe or are you across the room from them. Are you in the same room for hours and hours or just one hour? Essentially no, not unless you are right next to the person and inhaling from their exhale and doing this for hours on end. Best not to be in the same room if you have to take any kind of a drug test this way there are no ifs, ands or buts that you will be contaminated.

Yes it is possible, and if this is for a probation test, just being with them is also a vioation
