Has anyone made an entire practice out of psychedelics

[electroBeam]

Has anyone made an entire system for psychedelics?

When i say system i mean entire school for getting to enlightenment just like yoga meditation kriya etc.

How do you integrate what you've learnt in a paychedelic trip?

How do you remember very high doses?

How do you enter a trip so that you observe the state as accurately as possible?

 

A lot of these answers can be duck taped together using epistemology, meditation, following intuition, but is there any system out there?
