I think opioids are in a very special spot. There are very few drugs that are as intensely addictive and as harmful as opioids and are used in medical profession. In particular, ketamine is nowhere near as addictive or harmful as opioids. Your point is valid, we should be careful, but we should also recognize the special status of opioids.

>I'm not against it being used but we need to be careful, we don't want another opiod crisis.

This is a horribly ignorant statement. Ketamine therapy is in no way comparable to widespread opioid prescription in risk. You are once again comparing drugs with entirely different mechanisms of action.
