I'm posting anonymously on purpose. I work in Scottsbluff, Nebraska and in my profession need to work with various law enforcement agencies. What they have been telling me is that since Colorado legalized pot, they have seen a huge increase in people bringing pot into the state. That is the difference from a dry to wet county.
Now, the folks they are stopping are being stopped for other things first, such as speeding. These folks also aren't bringing back a little for themselves. They bring so much that it's obvious that it's for sale. I know of one stop earlier this year near Kimball, Nebraska of folks that were trying to take pot back to Minnesota to sell.
You have no clue what you are talking about. The prices of "legitimate" cannabis purchased in Colorado are around 35% higher than black market cannabis you can purchase in neighboring states due to increased overhead and high taxation levels. While I have absolutely no doubt in my mind there is an uptick in college kids carrying across a single ounce or two, no dealer or wholesaler in their right mind would procure from the legitimate market and transport vs. obtaining it on the black market or producing it themselves. The math simply does not work unless you somehow found people willing to pay a 50-100% markup over the existing black market in their state.
