I see more and more the "getting hooked on opioids due to injury" discussion and I know it is very important for education. But beyond that, I hope society is careful not to lean towards somehow dividing substance abuse problems into classes of moral origin.
Addiction and alcoholism is what it is, regardless. It's devastating and nobody wants it -- and in practice it matters little how they start/manifest themselves. It is not immoral or weak to have an addiction to alcohol or drugs. And one path to that end is not more understandable (or somehow more "OK") than another. For anyone who does not have an alcohol or drug problem I would suggest a few prayers of gratitude to celebrate your good fortune.
My kids have had the benefit of never seeing their dad drink. I like to think that I am a good husband, friend, and father --i.e. just an average person. However my history tells me well that if I have one drink today, or one codeine pill, or whatever...... the rodeo starts again. It matters not whether I take that drink or drug for a "good" reason (he was just celebrating his daughters wedding ..... or he had a bad knee injury) or a "bad" reason (he saw the drink on the table and just picked it up -- I bet if you asked him yourself he'd not be able to tell you why today was different). Result is the same -- buckle up everyone, it's going to get bumpy.
Substance addictions and alcoholism affect all manner of people and do not in and of themselves make people good, bad, brave, cowardly, tough, weak, or anything at all.
