There will be some conflict and confusion as this all gets settled. But, I think it will open up the doors to things getting better and may even lead to these issues getting to the Supreme Court. That is who really needs to overturn things because many of these anti cannabis laws are blatantly unconstitutional, but were enabled by past court justices. One bad precedent being the ruling that Cannabis has no religious implications under the first amendment.

But, for concealed carry in Ohio, I would imagine that there will no longer be justification of that law and that as schedule 3 you should have ADA protections that should nullify that law, especially if you can get a doctor to write a note explaining that it will not affect your ability to own or operate a firearm. I'm not a lawyer, so hopefully I am correct...
