Combining psychedelics with meditation opens the very real risk of conditioning one's meditation practice to require psychedelics to have any efficacy. When not taking psychedelics and meditating one will attempt to re-create or grasp after the pleasant sensations and thoughts previously experienced, which severs one from looking into the present moment as it is.
This undistracted state of [the] ordinary mind is the meditation. One will understand it in due course. Gampopa (d. 1153)
