Hey Bama,
If they are snorting, it is likely Buprenorphine (Subutex) which is meant for
sublingual use but can be snorted or injected.
Suboxone is not absorbed well into the body via any method other than sublingual.
Suboxne is Subutex with Naloxone added. Naloxone is a drug that precipitates withdrawl. If you are addicted to another opiate and you use Suboxone, you are subject to be in instant withdrawl instead of getting high.
Regardless, it is evil stuff.
