I'm definitely not a Wiccan, but I grew up in a Wiccan/Pagan household and explored it a bit when I was a kid, had some weird experiences and then life shifted away from that direction in my early teens. When I started exploring psychedelics around 19-20, my first heavy, reality-shattering trip rekindled elements of some of those weird experiences in a new light. I've since gained a bit of a renewed interest in occult studies in general... but only in the tools as they're useful, rather than any particular belief system such as Wicca.
Regardless, Neo-Paganism in general seems more suited to psychedelic use and exploration than many belief systems out there... If only because it's a paradigm in which the psychedelic experience is not out of place. It's a spiritual journey that meshes perfectly with the psychedelic journey, which can open doors to some really incredible ways or relating to the world and the trips and, most importantly of all, grokking the ineffable.
There's no replacement for ditching the belief systems and going at the damn thing with eyes wide open... But if you just can't take your eyes off the map, it might as well be a map that details psychedelic territory better than "Here there be Dragons". There are actual tools in Paganism (even Wicca) that can be brought to bear in the psychedelic context, and they're not coded in ancient Hebrew poetry; they're explained in contemporary language
