I'm pretty sure this is a case of cruel and unusual punishment....that's why it's offered on a volunteer basis. Those who want the help can get it, just like alcoholics can take
antabuse to help stem their drinking problem, but the
court will never order you to take it.
Their method is more to the extent of ordering the completion of a substance abuse course, and a stipulation of the substance abuse class will be the supervised ingestion of antabuse.
