when getting busted with an intent to distribute weed on a drug free zone, what charges can i expect to face?

DA's are tough on school zone cases, more so in certain counties.  The sentence (if you plead or are found guilty...don't assume this will happen) will depend on a number of things: your history, if any, the amount of weed they are charging you with (2oz is a Class B misdemeanor), and the strength of the government's case.  Get in touch with a reputable and tough criminal defense lawyer who has connections in the county where you are charged.  Many of us will offer you a free consultation on these types of cases.  Once you've interviewed a few lawyers, hire the one you believe can help you the best and keep you out of trouble.  Best of luck, hope I helped.
