Back when every state and its grandmother started banning my Actifed from shelves to get the home-grown meth labs de-supplied, Jim Pingel, the WI commission deputy director at the time, and I speculated what the impact would be on actual meth availability and who would deliver it. We concluded that the likely result would be that, with local entrepreneurs out of the picture, the usual suspects in drug trafficking would up their ante and, if we were really lucky, gangs would jump in like they have other drugs.
Boy, we were good.
(Another meth story today. Science Daily summarizes a Brown University study showing how meth use restricts fetal growth, complementing earlier work on cocaine effects. Jim and I would have predicted that if given the chance.)
