They better act fast if they want to skirt the law with yeast, while there's still a law to break.
It's still a good idea if you want pure chemicals - yeast can produce chemicals faster (to both grow and purify) than plants. Companies like the one Gov. Johnson is heading up would probably be very interested as a supply source for their refined products.
The trick is medicinal cannabis has something like 250 active compounds. A few years ago everybody assumed that it was only THC that did anything (marinol, for instance). Now they know that CBD is the most active medicinally and Johnson is now talking about CBG as well. There's still more unknown about the others than there is known, so focusing on just a couple pure chemicals might miss out on benefits. Human bodies do a lot of signalling with various cannabinoids and here's this one plant that happens to also grow most of them. It should be a biotech bonanza, except for the crapitalistic reasons politicians try to keep it off the market.
But, um, yeah, get high on THC beer if you want. It would actually probably be a net-benefit for society since people will be satisfied with being less drunk. As a user of the road monopoly, I'd strongly support THC beer on the market.
