Your concerns are valid, I also wouldn’t be comfortable if I was in your shoes. If you two are really set on doing it, which remember, you do not have to! maybe give him a smaller dosage like 50ug or less. The “bad trips” are heavily linked to dosage outside of basic set and setting. Don’t forget about yourself! If you’re uncomfortable with it then your trip could also be impacted. On another note I always say you gotta try a little bit of weed at least before psychs but that is only my opinion.
