That would be weak evidence at best; the ratio could change because of relatively increased use in the lower 48. If Alaskan use trended downward after recriminalization in a way that lower-48 use did not, that would indicate that legalization for Alaskan adults did impact teen use.
I got the link from TKDietz. I'll post it upon seeing your admission.
As I said before, without your admission, why bother doing the work?
As I said before, to establish that your previously cited factoid had any significance. (And since TKDietz gave you the link, what "work" are you whining about?)
Yeah, well, there you go. Very possible that teen use in the U.S. doubled to equal that of Alaskan teen use.
Adios.
