If it is just a ticket, and no criminal charges were filed, your should not have to appear. If you don't appear on a ordinance violation, generally the court will just enter a default judgment against you and find you guilty and order that you pay the fines. You should consult with a criminal defense lawyer in the area who will be able to advise you on how to best proceed. He or she may be able to appear on your behalf. You may get one or more of the citations dismissed and the fines reduced. If it is a criminal charge - both possessing marijuana and possessing drug paraphernalia can be tickets or criminal charges/misdemeanors - you must appear in court and your failure to do so can result in a warrant for your arrest. So I would talk to a lawyer in your area who can explain things to you more thoroughly. And stop admitting to criminal activity on the internet. Good luck.
Sit down with an experienced criminal defense attorney in your area to discuss at greater length. If you have to go to court today then ask for a continuance when you get there to talk to an attorney about how best to proceed.
