I'm not opposed to psychedelics in any way (in fact very supportive), but not having a control group seems non-scientific to me.
Maybe this is the scientific method hardliner / rationalist in me, but to me, without a control group and proper statistical controls, there's no difference between this and say, alternative medicine, such as homeopathy or acupuncture, where people claim there are benefits without a true comparison.
