Well, you're completely wrong here. The law has had a significant impact on the number and size of meth labs across the country.
But is it on a national whole, as we should expect? I've yet to see, other than on local levels, a 'significant impact' upon the meth lab industry. It's far too little to be significant, but, really, that could be just my view.
See, I find that when you search it, the cut down is seen on a state by state level, rather than a national whole. Sure, there is a cutdown, but it isn't what we were expecting. We were expecting more of a national cutdown rather than a state by state.
