As you may recall, Oklahoma was one of the first states to pass laws restricting the sale of cough medicine in order to supposedly reduce the incidence of methamphetamine abuse.  I know... you're just as shocked as I am that meth is still the drug of choice in that fair state:

The rash of methamphetamine-related incidents in the Tulsa area only seems to underscore the assertion that meth remains the drug of choice in Oklahoma.

"Methamphetamine, which is produced in Mexico and the southwest United States and locally produced, remains the principal drug of concern in the state of Oklahoma," according to a U.S. Drug Enforcement Agency report.
...
In 2004, Oklahoma led a nationwide movement by enacting a law restricting the sale of over-the-counter cold medicines that contain pseudoephedrine, a primary ingredient in the illicit production of methamphetamines. More than 30 other states have enacted similar laws since then.

As a result, meth lab seizures in Oklahoma have fallen dramatically, from 1,193 in 2001 to 274 in 2005. Unfortunately, the drug flow from Mexico has increased to supply Oklahoma addicts.

That's right... local meth labs have decreased, and in it's place we have the same amount of meth on the streets, and an increase in violent crime associated with the black market trade and gang activity from Mexico.  Of course, when your family is sick, it's nearly impossible to get the appropriate drugs to help them now, but you can comfort yourself by knowing that your inconvenience has done absolutely nothing to reduce drug abuse, or help anyone whatsoever.
