 They will be almost certainly. There's a big multi-centred trial going on at present. But let me just say one important thing about this. So if you're depressed, don't go out into the woods and start eating mushrooms. These treatments are one-offs. You have them in a therapeutic setting. Don't do it by yourself. Don't start self-medicating with mushrooms, please. Professor David Nutt, thank you so much for being here and sharing your fantastic knowledge. It's been a pleasure. Thanks for asking me.
