Drug Possession: First Offense Marijuna Possession in Michigan

My question involves criminal law for the state of: Michigan

This question is about my boyfriend. Three years ago he was pulled over in Oakland County Michigan for a tail light and the police found under a gram of marijuana in his car. He also had a suspended license. So he was arrested for possession of marijuana and driving on a suspended. He spent the weekend in jail and was released on a personal bond. His intent was to get a lawyer and go to court. Well it didn't work out that way and he never went to court. Well he recently started a new job in that same area. The police showed up at his job and arrested him for the warrant for possession of marijuana and driving on a suspended license. When they picked him up they also found under a gram of marijuana in his coat. I spoke to the officer at the jail. He told me his charges were two charges of possession of marijuana and driving on a suspended license. He also had one warrant for a failure to appear for a traffic ticket out of another county but he said they were unlikely to come pick him up. He is now in jail. His total bond amount is $1,500 (too much for anyone to get him out). He has already been arraigned and is awaiting pretrial on Wednesday (February 27th). My question is kind of vague. I would just like to know what we could possibly expect to happen at upcoming court dates and possibilities of the overall outcome. He is planning on pleading no contest. So far they haven't offered him anything or told him anything. Also, how long could it take for him to be sentenced after the pretrial? Thank you!
