Are we creating more addicts?

Medication assisted treatment (MAT) is a valuable harm reduction tool in the fight to reduce death from overdoses. That is why it's called a harm reduction. However, MAT does not treat the underlying addiction. Are we guilty of prescribing harm reducing drugs as a first reaction even when they may not be needed? Are we giving buprenorphine (suboxone) the seriousness it deserves? It is an opioid drug combined with another drug (narcan) that stops the user from feeling a high. It is itself, a highly addictive substance. Is it is the opioid that causes the brain damage or is it the addiction which causes the damage to the brain's reward system? If it is the opioid causing brain damage then how does buprenorphine, a stronger opioid, help heal the brain? If it is the addiction causing the brain damage, then how are we healing the brain by dispensing another highly addictive substance? If someone is abusing drugs but has not yet suffered brain damage or is not severly addicted and they take suboxone for a period of time, they will be addicted to the suboxone which is likely to be more difficult to withdraw from then the drug they began taking it for? I think that we are not healing an addicted population but only managing the addiction and the outcome is less than sufficient. When the money dries up and no one is able to afford the medication assisted treatments, treatment centers will become less available and there will be thousands of addicted souls looking for help.
