Question - why can't they just get/make the ingredient they are taking from the Sudafed somewhere else?
Those are tiny little pills.
P.S. Sorry if this is a dumb question, have never actually made meth.
It's not a dumb question and not asking questions is really the only dumb thing you can do.
Education is always the key.
[ame="http://en.wikipedia.org/wiki/Methamphetamine"]Methamphetimine[/ame] is the drug commonly referred to as meth, ice, glass, speed, tina, etc. It is commonly derived from a complex process extracting [ame="http://en.wikipedia.org/wiki/Ephedrine"]Ephedrine[/ame] from the pills that people are trying to buy in bulk.
As far as purchasing the base chemical in bulk, if you were somehow able to do so it would raise major flags. In fact most chemicals associated with meth are very carefully tracked and monitored.
The biggest problem with meth is the number of recipes available to make it. Since it's ultimately a complex string of chemicals people are constantly discovering new ways to make it. Traditionally it required a "cook" time in which it was heated. Since it involves extremely volatile chemicals it's incredibly dangerous. Apparently there is now a new method utilizing instant ice cooling pads and wraps that doesn't require cooking.
Any more questions?
