...because psilocybin was much more effective? On reduction, 83% efficacy vs 50% is huge. Stopping excessive drinking entirely, in half of participants vs a quarter is, let's see, twice as effective. How is this not obvious? If these numbers were associated with a vaccine, where one had a few more mild side effects but with the equivalent increase inefficacy, no professional would argue for not using it.

My concern treating obesity by replacing binge eating donuts everyday with eating a tiramisu every 6 months is that you're just swapping one substance for another. This is how dumb that sounds.
