What's with stupid drug makers?

But the type of person who would run a meth lab is generally going to be an idiot. I guess that just seems obvious to me. An intelligent/rational person would generally avoid running a meth lab.

The chemistry alone behind running a meth lab is quite astounding, actually.

You don't have to understand the reactions to make them happen. You just need to know what to do, which can be fairly easily found on the internet.
