A placebo would be far safer than the antidepressants on the market.

For me any t or Pdoc that violated the "trust" that is supposed to be inherent in therapy by feeling it is ok to lie about this issue and push drugs would be an epic fail. Without honesty in a therapeutic relationship there can be no forward movement. Therapy doesn't take place in a vacuum and sooner or later a person is going to hear about this issue and question being lied to, any progress is then threatened. I have had therapists who disagreed with me on an issue like this and we just agree to disagree and go forward with respect for each other.
