Strong opioids are the only option that works for many people with chronic pain. In some countries (but not the US), heroin (technical name: diamorphine) is used for extreme pain, like late stage cancers. It truly is one of the most effective painkillers that exist - and it isn't unimaginably strong like fentanyl, so it's much harder to accidentally OD on when used medically.
