Just thinking briefly about this, I don’t understand why commerce would even be a issue with a drug that simply needs to be put on the class or schedule whatever list...which I assume it is...
If the problem is the smokable form, them maybe they should just allow that form of the substance and dispense it through the normal pharmacy distribution network with a doctor prescription.
Then get rid of all this medial MJ nonsense. and laws like Colorado’s which is just plain nuts.. After which you have a legal pharmaceutical the is regulated the same way as Oxycontin. Thus it would still be illegal to grow, but they will still do it, however it will be readily available via prescription.
That’s the only answer to this mess...But I don’t use the stuff...smoked it when I was a 60s hippy wanna-bee, but I note that todays MJ is nothing like the weak pot, we had back then. This new stuff is closer to a good hashish. Had a smoke a few years ago, it almost made me unconscious. It needs to be regulated.
The question is, by who and on what authority.
Which can be effectively done only with a legal product.
