Based my reading of that, what these researchers are doing is not prescribing psychedelics to patients with mental disorders and giving the whole "take one time a day with food". What these researchers are finding is that the drugs can be very effective in a therapeutic setting with a guide (trained therapist or otherwise) to coach and conform the experience to reach a goal. In other words to those familiar with these drugs, set and setting. That is, mindset and surroundings are at least as important as the drug itself to achieving anything. Without that, it's just a drug experience. This is very unique compared to the drugs we're used to.
No medication will ever be a miracle drug, and most drugs show a significant decline in effectiveness once they're out of small trials and methods have standardized. However, any drug or therapy that sees orders of magnitude of improvement over existing drugs and therapies is promising and not worth dismissing simply because of a moral panic from the 60s or the Puritan ideals of our Western culture. Given time and the leeway to experiment, hopefully we will find uses for this class of drugs that have gone shunned for decades for no reason other than someone's moral qualms.
