It's quite likely that any such increase is largely if not entirely an effective relocation of the supply for nonlegalizing states - relocating either from those states or from abroad. One of the downsides of being among the first states to legalize.
Yes of course, dopers refuse to think there is a single thing negative about mj or legalizing it.
Why would heroin junkies and meth freaks move to OR just because mj is legal?
It’s the ..... read carefully.... DRUG CULTURE. It becomes socially acceptable in general.
The idea that meth tweakers and heroin junkies MOVE here is stupid.
