Buprenorphine is a partial opiod agonist similar to how thc is a partial cannabinoid agonist. Partial agonist mostly meaning there is a limit to how much it will stimulate its corresponding receptors. Naloxone is a completely different drug, given in combo with bupe in brand name suboxone. That quotation provided by coffeeshrrom is only really relevant to someone taking suboxone as alternative to high amounts of opioids, who might also be considering getting high off large amounts of their prescribed partial agonist opioid(suboxone).
To the OP, seeing by your other post that you are already passing out from smoking weed... adding a downer probably won't make it any better. If you have no opioid tolerance and lightweight weed tolerance, you might even catch some nods... which may or may not be your goal. Really you'll probably just get way higher, possibly nauseous and dizzy, then hungry and tired.
