>A much better solution to the problem of secure sales of controlled substances is to eliminate conventional distribution. (I think we may have discussed this more than two decades ago): use genomics.

Well, yes, not too long after I moved to the Pacific Northwest in 1980, I joked that "somebody" should insert the gene for making THC into the blackberry plant (which grows virtually endemic here!)  and spread the seeds by some kind of crop-dusting operation.  

However, I don't keep up with DNA technology, other than occasionally reading a public-media article.  I have recently seen an ad for full-sequence DNA testing for humans, at about $500.  I don't know if this would be automatically applicable to plants or other animals, including marijuana plants, but I certainly wouldn't know how to find the "THC gene".  But, experts would know that, I think.   I suspect both plants have been full-sequenced by now.   How to transfer the DNA, I also don't know.
