Sure, but isn't that exactly what we would be trying to treat? I would like to believe in hallucinogenic therapy, but if it can cause an underlying problem to expand to the point where it causes a negative change in behavior, that's not good. It would certainly depend on the risk, but having a risk of triggering a mental illness the person was previously coping with is not a good thing. Finding a way to deal with your problems is the best solution. In lieu of that, I would argue coping with them without handling them is the second best, with neither handling them not coping them being a distant last place.
