> Clean heroin is one of the least problematic substances appearantly, less problematic and more "everyday friendly" than Methadon even.

Least problematic is too strong of wording. Consistent opioid use will take a large toll on the body and mind. A therapeutic level of dosing could possibly be better than severe chronic pain depending on the situation, but even chronic pain patients have to deal with a range of negatives and side effects that are only tolerable because they’re less bad than their severe chronic pain.

Chronic opioid use induces a lot of changes in the body and mind. The initial euphoria isn’t sustainable, as everyone knows, but long term use induces even further changes that predispose users to deeper depression and can even begin to augment pain signals.

Opioids are in a class of drugs that are unusually deceptive because users who more or less control their dosing will talk themselves into thinking they can do this forever without real negatives. They can go for years before the cumulative negatives become too obvious to ignore.

For addicts deep in cycles of rehab-relapse extremes, going to a maintenance program and achieving stability is definitely better than continuing the cycle indefinitely. However it comes with a high price relative to sobriety. I think it’s important to not downplay the effects of being on opioids for years and years.
