Like now, when they point out the absurdity of restricting OTC cold medicine to combat meth production: Where Have All Our Cold Pills Gone?

The ONDCP [Office of National Drug Control Policy] cites declines in meth lab seizures as evidence that the peudoephedrine restrictions are working. But as state officials have acknowledged (and as anyone who was paying attention could have predicted), the decline in local production has not reduced the overall supply of meth, because the vast majority of it comes from Mexican traffickers who are not affected by the Dayquil crackdown and who were happy to pick up any slack. There is no evidence that forcing cold and allergy sufferers to register as suspected meth manufacturers has had any impact on meth consumption.

We could’ve told you that, nobody asked.
