Is there reason to believe that restriction on pseudoephedrine is having a larger effect on shake and bake production than the relative cost? I'm not really paying a lot of attention to the issue, I think I bought one small package of pseudoephedrine in the last 5 years and the biggest issue I had is that the pharmacy tech didn't assume that I meant generic when I said I wanted the cheapest one.
