Well, that's a far more nuanced argument than yours. Frankly, you'd be better off quoting that than making veridical statements such as 'does not' when your own evidence indicates it 'sometimes' does. Certainly opioids are not a front line treatment, and never were, but I would avoid going around saying they 'do not work' when clearly sometimes they do and it's a highly contextual decision. You may want to say instead that there is little evidence supporting their widespread use in long term pain management as a primary strategy. That would be supported by what you've posted and I'd take no issue with that statement.
