Combining a classic psychedelic (e.g., psilocybin) with psychotherapy may produce benefits that are synergistic—greater than the sum of each treatment alone—but current trials have not tested this directly. Most studies pair the drug with some form of psychological support, yet providing full psychotherapy is more costly and harder to scale than basic harm-reduction support. Factorial designs, in which patients are randomly assigned to drug plus psychotherapy, drug alone, psychotherapy alone, or double placebo, can isolate the separate contributions of each component and detect true synergy. Such trials require large sample sizes but could determine whether the added expense of psychotherapy is worthwhile for improving outcomes in conditions like depression, anxiety, and chronic pain.
