My SWAT teammates who are on the Drug Enforcement Unit describe meth lab busts where they find huge quantities of OTC pseudoephedrine.
Pay attention the next time you are in a store like WalMart. You will see opened, empty, discarded pseudoephedrine packages stuffed in the back of the shelves. The thieves even pop the pills out of the blister packs.
Just another effect of the drug culture. Now we have to buy OTC cold meds, well, actually OTC. No longer stocked on the open shelves.
At least in my community, we don't have to sign for it. But that's probably coming.
