In 1969 at Kadena AFB The Air Force was getting concerned about the widespread use of marijuana among the zoomies and we had a mandatory lecture at the movie theater. A lawyer and a doctor and a chaplain and the base commander each described the evils of pot from his point of view and admonished the troops to report whenever they encountered the smell. Then they passed around baggies of a green purportedly synthetic substance that was said to mimic the smell of burning marijuana. The doctor, I think, said the substance was primarily equine manure. On the way out I after it was over i heard an old sergeant say to another sergeant, “27 years in the Air Force and this is what I get, a bag of horse shit and they don’t even let me keep it.” And yes, if you go to visit a horse farm you might think you are smelling marijuana and it might bethat or it might be horse manure.
Believe me, pot and horse manure do not smell the same. Horse manure smell is preferable.
