The courts could request this and your Probation Officer. If you are into sports or your workplace has been informed of this then yes, they can request a drug test being done. My mind wanders on this one and I am wondering why you haven't gotten the message yet!!!! Drugs fry your brain! Likewise, in the US random drug testing will be implemented against those persons who are on probation until they have successfully completed the probation period. A positive drug test can result in the individual having to serve the original sentence that was suspended in lieu of probation. YES, THAT PERSON WOULD DEFINITELY IMMEDIATELY BE SIGNED UP FOR RANDOM DRUG TESTING TO MAKE SURE THEY DON'T DO DRUGS AGAIN, TRUST ME, I SHOULD KNOW.
