That depends on how accurate their speculations are, and of course how credible the sources in the first place.

I still suspect that the situation could very quickly turn to more of a shortage once the state gets serious about eliminating the illegal grow operations.

Just have to wait and see, but I find it hard to believe that there'll be a near term glut of legally supplied MJ as the illegal sources are dealt with and reduced.

Obviously that won't be resolved overnight, but those willing to deal in illegally obtained MJ can also be expected to drop off as cracking down on the retail end is also inevitable. The track and trace system was designed with this in mind.
