Drugs are like any industry I would guess, in that, economy of scale will eventually win the race by using industrial practices. Much like how cocaine went from high quality to low quality as demand skyrocketed and the scale of production was more important to producers than quality. But, as the industry scaled to the demand, the quality climbed due to better production practices. I guess my point is that meth's growth is probably the leading cause of any drop in purity as opposed too any action by the government to limit small distributors. As the big players in the industry scale their production the trend "should" reverse? Just opinion.
