Eheheh, Back when I was a little younger and quite reckless, I was fond of chaos magic and "The dark arts". More than once have I ingested a hefty amount of something or another and invoked a being of delirium and euphoric madness, for better or worse. Generally if I am working with rituals, I like to be clear minded. There is also the problem of, depending on the ritual, the large amount of spoken content to remember.

It is quite a pain in the ass when your trying to do something very "serious" and the only thing you can seem to do is chuckle while the spiraling vortex of psychedelia is ravaging your mind.

I do enjoy a good meditation in the forest on mostly any substance though. Tuning in to nature and the unseen energies around it makes for a very balancing and rejuvenating experience, and the entities I find there are generally quite pleasant.
