In Missouri its illegal to bring hemp or Marijuana in any form from out of state it has to be grown processed in Missouri to sell.
We just had a couple companies loose their licenses because they were using converted hemp delta 9 from out of state to make edibles. It’s even illegal to take converted hemp delta 9 grown here and add to marijuana products. You can sell hemp delta 9 products grown and processed here but they are all 0.3%
