My friends court date is soon and he has incomplete NA meetings?

After being caught in the posession of mariquanna (twice) he received an extention on his court date and was court orders to 10 or so ( idont remember how many exactly) NA meetings. I've been on him about getting them done for the past month or so and now his court date is in a few days and he doesn't have a single one done. What are the chances of him going to jail on the spot and is there anything he can do to avoid it? I'm not too literate on all the rules and laws and such within the court system...especially when it comes to things like this so ANY info. would be greatly appreciated...thank you so much.
