It should be noted that in 2001 a patent application was filed with the U.S. Patent Office by G. R. Barrie Webster of Manitoba and published on July 22, 2004, regarding the conversion of cannabidiol (CBD) to tetrahydrocannabinol (THC). That application cited earlier work by Gaoni and Mechoulam that converted CBD to THC. Thus, while it can be done to produce yields up to 70 percent THC, one would need access to key chemicals, certain acids, organic solvents, nitrogen, methylene chloride and other substances. Again, if the object is to get “high,” converting CBD to THC would generally not be done, because it is costly, labor‐intensive and unnecessary given the availability of cannabis‐THC.
