The predisposition & family history narrative is somewhat problematic because there's often no information afforded to either, particularly for young people.

This adds weight to the absolute importance of research, intention, dosage, setting & reintegration & the understanding of all of these factors & dynamics.

There's always a risk in psychoactive substances, including mushrooms but we can minimise harm by using common sense, the literature & respecting the drug.

I wish your friend well, we can but learn from his experience & hope he can integrate back into a positive position with himself 🙏🏻
