"I think it is obvious that this has been a nationwide trend over the last 20+ years. See Figure 22 :"

In looking at your Figure 22, yes, prices are down over a 20 year period. But according to the same chart, prices have been flat since 1988 (as are the number of users - Figure 23).

Gee, and you'd think with all of the interdiction efforts and all of the people imprisoned since 1988 that prices would have gone way up and use would have gone way down. That is of course if this whole fiasco of a drug war actually worked. As long as there is demand it will be met. Success cannot be measured by the amounts of drugs seized or the numbers of people convicted and sentenced to prison.
