You're in WA and have access to freebase amphetamine in paste form, like they get in Europe? If so that is really more interesting then what your going to do with it... are you sure its not just some crude methamphetamine? I only ask because I am pretty sure "speed paste" is a freebase form in Europe and whether or not you have a salt (as is common in the US) or a freebase will determine what you can do. I have never seen anything other then pharmaceuticals so I cant really answer more then, make sure you know if its a salt or a freebase before doing it.
