If you were to survey Texas residents to find out approximately how many have, at some point in their lives, faced some type of legal problems, the results (if participants were to be completely honest) would likely be high for those who answer affirmatively. Some would probably say they'd had a traffic ticket or two; others perhaps have dealt with more serious matters.
You yourself might currently be facing criminal charges of some kind, maybe drug-related or a DUI, and are feeling a bit overwhelmed or alone as you prepare for what lies ahead. It's always good to remember that you are definitely not the first, and most probably will not be the last, person in this or any other state to face charges in court. However, understanding that it's no small matter, you'll be doing yourself a favor if you seek clarification of your rights and possible defense strategies ahead of time.
