There is a limit in the act right now, and there's certainly no legislation coming forward that I'm aware of that deals with raising the penalties for precursor chemicals. Until they are put together into other things, precursors are not as dangerous; therefore, if you just happen to have too much of one of them kicking around for some reason, you face the lower penalty.
In this legislation, if you have it, or three or four precursor chemicals plus the necessary equipment to cook it together, etc., you're facing ten years, because presumably the court would be able to assume that you got all of this stuff together and that your intention then was to produce methamphetamine.
