Standard UAs for alcohol use do not detect other than ethanol or it's metabolites. Likewise, standard drug panels do not detect alcohol use.

Court ordered drug screens almost always involve at least basic 5 panel tests which do detect cannabis.

It depends on the test, which depends on the order of the court and/or election of the probation officer.

Usually they will test you for alcohol, however, there it depends on where and how you are tested. Most labs will run a full panel which includes all drugs, as well as alcohol. Good Luck, and God Bless.
