Every jurisdiction will be different. I've been caught in a few places. Some want a piss test before the end of court to show you've been staying clean since, some places don't bother with it
Bro there's 1000s of different jurisdictions. Some places give it to you the day your caught, some places contact you with it. GC isn't the place for legal advice, there's way too maNY ways things are handled depending on the location and the charges. Some jurisdictions might just slap you on the wrist, while others will fry you. contact an attorney that handle cases in that jurisdiction for advice.
