Biohackers Are Engineering Yeast To Make THC 159

Posted by timothy from the really-great-bread-man dept.
meghan elizabeth writes How do you get weed without the weed? By genetically engineering yeast to produce THC, of course. Once theorized in a stoner magazine column more than a decade ago, a biotech startup working in Ireland is actively trying to transplant the genetic information that codes for both THC and another cannabinoid called CBD into yeast so that "marijuana" can be grown in a lab—no plants necessary.

    So let's say I start a company that uses GMO THC yeast to make bread dough. The dough does not contain any THC; just the yeast that can create it. I sell this bread dough in your supermarket's freezer section as unrisen, unbaked loaves.

    You purchase the bread dough, take it home, thaw it out, let it rise overnight. (Or, for an hour or two in a warm oven.) It happily produced CO2 and THC, the bread rises, you then bake it. You then can make some 'fun' sandwiches. Is my business legal?

      If it's legal it won't be for long. Two points:

      1) Most likely the yeast bodies will have trace amounts of THC.
      2) Look at what happened with Psilocybin, the spores of the mushrooms contain no Psilocybin however the mushrooms do. You used to be able to order the spores legally because there were no psychoactive chemicals however they are now also on the DEA schedule.

      So .. no.

        The yeast is just a cover. Once they get it all sorted out, they switch to selling kits for changing human cells to produce THC directly. This also avoids the whole smoking step, which is probably more unhealthy than the THC itself.

      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 [benswann.com] 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.

      • Sure, medicinal cannibas may have 250 active compounds, but how many of those - individually or in combination - are necessary to treat 95% of patients?

        If we can identify the ones needed to treat the vast majority of patients and synthesize them or find a bio-factory (e.g. yeast) that we can control much better than the traditional source (the plant), we can deliver drugs that are more pure and more consistent than your average joint or brownie, yet still do the job for almost all patients.

          Minor point - IIRC weed was targeted by William Randolph Hearst back in the 20s. Hearst owned the largest newspaper chain in the US, and had bought the global rights to the new method for making paper out of wood. His goal was to eliminate hemp as a fiber source for paper. He set up a huge tree plantation in Guyana (or thereabouts) and began a major attack on weed. He began a publicity campaign in his papers about the evils of weed, funded the making of "Reefer Madness", and lobbied and bribed congresscritters to include weed in the Volstead Act as a dangerous drug.

          At that time hemp, which is a slightly different variety of cannabis, was a major source of quality fiber for rope as well as paper (and still better than any other vegetable fiber AFAIK). The hemp growing industry was destroyed. But even today, cannabis is a major 'weed' throughout the midwest, and is a primary source of seeds for birds.

          Once when motorcycling around the wilds of Illinois we came upon a large tract - probably 40 acres - of hemp, complete with a set of beehives. I have no idea if this was just fallow land or being grown on purpose. We came back with a car and collected one 14 foot plant for a Christmas tree in the dorm. The branches were two feet apart. Smoking was tried, it was pretty much smoking a rope.
