The worst thing the court could do is sentence you to the maximum sentence...one year in jail. DO NOT do this. You need to ask for a stay of execution rather than not show up.
Call me if you would like to discuss your options.
No answer here should be considered to form an attorney-client relationship. You should consult with a licensed attorney in your jurisdiction so that a full evaluation of the facts of your case can be conducted.
You would be charged with misdemeanor escape. Escape is easy to prove in your case and would result in a consecutive jail setence of up to 90 days.
You could face additional jail time, new charges, and/or a warrant for your arrest could issues. Take care of this now rather then later; it would only get worse with time.
The other attorneys are correct, the judge could hit you with more jail, 30 days, 60 days, up to a year. You should ask for a continuance and get everything done by the next court date. Also, you might be able to get work release over straight jail.
Marijuana is against federal law. Federal law supersedes state law. A person could be charged and convicted for marijuana related crimes such as possession, cultivation, distribution, manufacturing, transportation, and conspiracy.
