I recommend you take all of your drug making equipment, pack them into your car/truck and drive to the local police station. Ask the first cop you see if you could can make his day and show him your stuff and surrender.
Make sure you confess to everything they ask you about... this is key.
it really only depends what the charges are, all states have the right to extradite if they want, all you will have to do is call the clerk of court at the courthouse in the county where you are wanted and ask them what the warrant is for, and if it is extraditable, some will only go the neighboring states and some are nationwide. call up a police department in oregon and have them run your name for warrants and they can usually tell you over the phone if you are wanted, what for and how much the bond is etc....call anonymous if you are scared
