G-13 is the codename for a strain of
cannabis, possibly a mutant variety cultivated by the
American government during the 1960s. According to
urban legend, the
CIA,
FBI, and other agencies procured the best strains of marijuana from breeders all over the world. At an installation at the University of
Mississippi, they bred many new hybrids. Putting these together, they created a strain that was more powerfully intoxicating than any of the original hybrids. This strain, G-13, was a primarily
indica phenotype strain and provided a very potent smoke and a completely mellow high. Allegedly a single cutting of this potent strain was stolen by an employee at this government facility and released into the public domain. Other rumors say G-13 was developed by the
University of Washington's cannabis testing facility for medical testing during the 1970s, but this, too,
has not been verified.
