tbf I have always found it mind-blowing enough that CBD products such as ointments and salves are still not available in all 50 states since they do not get you high and can change lives
I'm always confused about how the State/Federal system works with things like this. I hear about dispensaries and the like being raided in states where marijuana is legal now and don't really know where or how a line is crossed.
In the cases where I have seen it happen it's always been because the shop crossed the line, in one case by opening a recreational wing without filing any of the paperwork, and in another when the dealer was selling under the counter and not checking ids.
I'm pretty sure that will change under Sessions
