Legal Question in Criminal Law in California

No, and you won't get any punishment at all unless you get convicted. Make sure you don't get convicted.

It depends on what the substance was, what the charge was, and whether there are sentencing enhancements alleged.

If this is charged as a felony, you face potential prison time. As a misdemeanor, then up to a year in jail. Effective plea bargaining, using whatever defenses and sympathies you may have, could possibly keep you out of jail/prison, depending upon all the facts and evidence. Not exactly a do it yourself project in court for someone who does not know how to effectively represent himself. If serious about doing so, feel free to contact me. I�ll be happy to help you use whatever defenses you may have. If you can't afford private counsel, apply for the Public Defender.
