I've been fascinated by Etorphine ever since it was mentioned duting a pharmacology lecture in the second year of my Physiologu and Biochemistry degree course. It is an opioid that is it is a synthetic relative of Morphine. However, it is many thousands of times more powerful. First synthesised in 1963 it is best known as “Elephant Juice” the drug that can drop a rampaging elephant in a second. just 4mg of the stuff will bring down an elephant, a mere 1mg does for a rhino - that is how powerful the drug is!
Quite astonishingly the Molecule of the Month (yes it does exist and has been featuring a different molecule each month since 1996) entry on Etorphine included the sentence “Scientists at BAT (British American Tobacco) once debated adding it to tobacco as it might create an addictive craving for it”
Etorphine in cigarettes? I seriously thought that this was a joke until I came across a 2003 article in the BMJ journal Tobacco Control Online (The link now requires registration) :
“... Dr Sydney J Green, then British American Tobacco’s (BAT’s) senior scientist for research and development. Green informed his readers about"way-out" developments at BAT including :
"A way-out development is that of compounds (such as etorphine) which are 10,000 times as effective as analgesics [such] as morphine and which are very addictive. It is theoretically possible (if politically unthinkable) to add analytically undetectable quantities of such materials to cigarettes to create brand allegiance. But this thought may suggest the possibility of such compounds occurring naturally."
Green’s report followed an earlier memo from Keith D Kilburn to CI Ayres, expressing concern about what BAT’s competitors might be doing in order to create brand allegiance. Kilburn proposed that a regular etorphine dose of as little as 0.2 microgram per day would be sufficient to create an addictive craving for the source. He also claimed that the "required delivery per cigarette…would be analytically difficult to measure."
Etorphine is extraordinarily dangerous stuff: fatal overdoses to vets (as in vetinarians) attempting to dart animals have been recorded. As a consequence vets who are registered to use etorphine must now have an assistant standing by with a dose of antagonist in hand.
I suppose one should not be surprised that Big Tobacco might have considered using etorphine as an additive, despite it being sheer and utter madness! It is just as well they never implemented the plan. On the other hand one would probably go down well after a coke Coke and a McOpium'n'cheeze burger.....
