not sure i understand doc?
it seems to me that all congress has to do is simply allow for individual state laws under the condition that the only cannabis 'cultivars' legal under each state law would be FDA approved /registered/permitted etc and i'm guessing that there would be some mechanism which would give genetically engineered plants the exclusive advantage within that process...just my opinion...and considering that Monsanto has done gene ohm mapping of cannabis under fed anti-bio-terrorism programs (at least) it seems they might be plenty ready for such a change in the law that in my opinion they are pushing hard for under the radar...
cannabis prohibition is not that simple.
the supreme court ruled that the congress has no power to prohibit cannabis, only to tax it, and several previous attempts to ban cannabis by requiring a "Tax Stamp" which was never available for sale, and never issued were struck down as backdoor prohibition.
the "Marihuana Tax Stamp" (lol) is still issued today, but only a few, and all are bought directly by a few universities running the
FOURTY YEAR LONG "study" on medical uses of cannabis, with
no results yet published.
after failing to ban weed by legislation, the congress created the Food and Drug Administration which they granted the power to "Regulate" dope, which immediately crafted regulations which banned cannabis, despite having been repeatedly informed that "regulating" does not allow prohibition...
thus, the congress gave bureacrats a power the congress never had, and the bureaucrats now exercise this power through the controlled substances list, which lists the SPECIES cannabis as a Schedule 1 drug (absolutely prohibited).
changing those regulations will require re-writing the entire Controlled Substances Act or removing cannabis from Schedule 1, and neither of those things are gonna happen.
any new cultivar of cannabis as well as THC (and all it's variants) are prohibited by the Controlled Substances Act through the magical power of bureaucracy to acquire authority from congress that congress never had to begin with.
the only way around this would be to issue a company (possibly monsanto) a fat stack of "Marihuana Tax Stamps", which would allow them to produce "Marihuana" but would still give them no power to distribute it, or any drug derived from it without FDA approval, which is also a highly unlikely scenario.
only synthetically created cannabinoids can be produced (lol demerol) and they are scheduled by the FDA just as any new synthetic drug would be.
creating some cunard where GMO dope plants were declared "Synthetic" would be very unlikely, and any patents on a new "synthetic" dope cultivar would only last 20 years.
Cannabis prohibition is trapped in a bureaucratic Pandora's Box, and the mandarins in washington aint even gonna think about opening it.
