As far as i know, this is not legal in any state. The only way it could potentially work is if you transferred the CBD (not THC) to your THC license in METRC, then do the conversion. And even then, I’m not sure it’s allowed.
In Oregon, you can transfer CBD from your hemp license to your cannabis license. However, once you do that the CBD can only be sold in dispensaries. You can’t transfer in the other direction.
In California it’s strictly illegal. All products must be tracked from seed to sale, meaning the Cbd has to be grown at a licensed California facility and no one is going to waste their grow space growing cbd when thc has a much higher market value.
As long as you are selling License to License, or retail in a licensed facility I am almost positive that would be legal.
If you are tracking the plants and concentrates made from those hemp plants in MetRC, just like you would THC, and selling it L2L, I can’t think of any rules you would be breaking.
But if you are just tracking it in MetRC but then trying to sell it online or in a head shop as “hemp derived THC” I would say that is certainly illegal.
It’s legal grey; better to ask for forgiveness than permission; if everything is in metric then it should be a non issue. Have all of your SOPs written out just incase you get any questions; be as transparent as possible.
Also never call it synthetic; just say you are utilizing post processing techniques to make the conversion, and it’s still all plant derived material at the end of the day.
