You need an attorney. If you don't have a prior record you may be eligible for Pretrial diversion.
My answers are only intended as general legal advice based on my eighteen years as an Austin criminal defense and DUI attorney. They are not intended to be a binding legal opinion nor to create an attorney - client relationship. For those questions asked outside of Texas, there is no intent on my part to practice law in any other state There is no substitute for contacting a local attorney.

If you have court in Dallas tomorrow you have to appear. Even if you're a student you OR YOUR ATTORNEY need to be there. As a first offense, you can get a deferred for marijuana possession but if you push you can get a Memo Agreement. Generally only attorneys can secure a memo agreement which is like pretrial diversion. Complete a period of usually 60-90 days without getting in additional trouble and the charge is dismissed and can then be expunged.
If you can't be there tomorrow, you need to hire an attorney tonight. If you can be there tomorrow you need to be prepared to hire an attorney. I handle misdemeanor and felony marijuana possession cases, so feel free to contact me. In fact, I am finalizing a deferred on a possession case in the morning and will be at the court house if you want to ask any questions. Feel free to email or call.
You need to have a lawyer represent you. You can appear the first time without a lawyer & tell them you are working on hiring a lawyer; you will get a reset. Call 3 to 5 lawyer to discuss your case then meet with a couple & make a decision. Depending on the facts, you may have a suppression issue.
