And so what you do is you do therapy plus MDMA and you do therapy plus placebo. It's not a bad idea in principle. It is a bad idea if we know that the group that gets MDMA will know they're in the group that gets MDMA. And perhaps even more problematic, and that's something we don't talk about too much, folks getting placebo know they're getting placebo.
