Info on oripavine?

[Ontherooftops]

Octopus is quite curious about the action of oripavine on its own. He is aware it is a step in making some stronger opiates, and is the basis for buprenorphine, but has read some interesting things about the action of oripavine on its own.

Octopus found something stating 4mg/kg had similar analgesic action to .5mg/kg morphine. He wishes his understanding of organic chemistry and pharmacology were better. He has also read some things saying that oripavine has some antagonistic action on opiod receptors...

It seems there is some addiction potential as well, demonstrated by self admin in monkeys.

Would oripavine be safe to assay, would it make swim's octopus unhappy?

Do any SWIYs know about this substance?
