My question involves criminal law for the state of: Michigan

I was wondering, if in a felony manufacturing/distribution of marijuana case, what does being under advisement entail? Does it last as long as probation would last, or does it last longer? (Assuming I get probation and not jail time which is looking good right now.) It's my first offense with a clean record, going to school, had a job before I got up to school, and I will piss clean if they decide to test me.

Thanks
