Robin Carhart-Harris, who's currently the most influential researcher in the field and proposed both the entropic brain hypothesis and the REBUS model, is "no comment" on whether he's ever used psychedelics. He neither admits or denies it and has said "It's a lose-lose situation" because admission or denial will lead to biased perception of his research from different sociocultural groups.

He's trying to protect his research from other people's bias, not his own.

How important is it to develop novel therapeutic techniques, or even environments, for use with psychedelics?

How hard will it be to quantify the therapeutic value, or dangers, of psychedelics in relation to different therapies and therapeutic environments?
