A meta-analysis of eight studies found that psychedelic drugs produce a rapid and sustained reduction in depressive symptoms, with effects appearing as early as day one and lasting up to six months. No serious adverse effects were reported, though transient increases in heart rate and blood pressure occurred compared to placebo. The analysis included studies published through April 2019.
