It may be concerning, and there is always a part of the media that wants to incite "the sky is falling". If they can do that and sell papers, they have done their job.
The reality, I suspect is a little closer to this. The feds won't get involved until it comes to crossing state lines, same as it always has been. In the whole scheme of things, this is truly small potatoes to them. Move a couple million in weed from Maine to New Jersey, you're gonna catch their eye, of course. Johnny growing a couple plants in his back yard and sharing a joint with his buddy..... does anyone really think the feds are going raid his back yard?
Where this could get interesting is much like the NFL has handled it. They are very clear that they don't care if certain states allow, the NFL does not, part of the deal. If you want a federal job, it might behoove you to play by their rules and make sure you don't fail one of their tests. The federal jobs do a whole lot more testing than a mom and pop sandwich shop.
While I agree with you on the media I listened to the press conference last night and can only say I walked away from it feeling concerned. There's a lot of money between Pharma, private prison lobby, police unions and alcohol/tobacco. Mr Sessions isn't exactly pot friendly either.
Why would they link use of cannabis to an increase in opioid use...there's been studies that suggest the opposite. To me this sounds like a reboot of the war on drugs and I'm thinking the checked just cleared from one of these lobbies(private prisons???).
If it all goes as you stated then ok, fine but its pretty early in this administrations tour to be bringing up stances on this considering other things going on around the world. I guess we wait and see
Edit-I just realized I got going on politics which I generally dislike online, especially here in particular. To anyone reading this I apologize but its sorta in context for this topic.
