What will they cook up next?

In their work to ensure that only the good (read: taxable) drugs are in the hands of consumers Iowa State University scientists are helping in the fight against Meth. Apparently, chemists found that the popular anhydrous ammonia fertilizer often siphoned by meth cooks could be rendered virtually useless to them by adding a small amount of calcium nitrate into the mix.

Actually, making meth harder to get is a good thing. I also suggest declaring mullets illegal as a further deterrent to meth use since there is obviously a correlation there as well.
