I was charged with a mip last night and wanted to know what charges I could face.?

I was charged with a mip last night and wanted to know what kind of punishment I could face. It was by consumption and I live in missouri. Is there any way to avoid probation, community service, or get the charge expunged from my record. This is my first offense, and I was also within a gated community behind the fence when the cop pulled up outside of it and asked me to come to the car, if that matters at all.
