LSD can greatly enhance meditation experience, make it much deeper, more emotional and more healing. It will also make it more uncomfortable, which is just a reflection of its efficacy. Same goes for magic mushrooms. Just don’t take too high a dose - you don’t want to get completely lost in it. There’s nothing wrong with being completely lost in it, it just won’t feel like meditation then, but a trip. If you want to meditate on LSD, consciously, find the right balance.
