I have a stash of left overs -- nothing like 30 mg -- for pain relief after I had some dental work done.
It helps deal with pain but I find it to be a shitty high. IMO. Fucks up my sleep too. I'm in no way tempted to dip into it for fun. That said, I sympathize with people who either casually or accidentally became addicted. Treat as a disease. Maybe use medical MJ to help overcome cravings once the patient has gotten through withdrawals. States that have legalized are seeing decreased use of opioids too.
