The same can be said about people who see/talk to spirits but don't take any drugs - but it's probably more worrying than the drugs in most cases - seeing that sort of stuff when you take psychedelics is pretty 'normal' (but be warned: being the fickle mind, if you go in wanting spirits, you're as likely to come across devils or souless robots or nothing at all (the mind's like that - like trying not to think about elephants)
Also, as i understand it spirituality doesn't really mean that you specifically believe in individual spirits that go somewhere after death (that's spiritualism i guess). My view is i believe in the soul/spirit, but there's only one and we all share it (i could just call it 'life' or feynmans single electron (or brahman)) - this is a pragmatically chosen belief (albeit influenced by intution, psychedelic experience and my hippy/buddhist parents) it matters not how 'true' it is.
Faith can be a dodgy one: faith in a person is one thing (a big component of love), similar to faith in humanity - but faith in a written dogma or an authority can't logically be required of any putative 'loving god' when that very loving god is meant to have created the curiosity and thirst for knowledge that questions the basis of the faith in the first place. If there is a creator god of that sort, the critical thinking, questioning, iconoclastic, rebellious aspects of our nature would be some of her best works - only a non-loving god would have made that as a trap for those not sufficiently pious (bit like sex really). Faith that 'everything will be alright in the end' is better, but faith in some divine plan that everything happens for a reason risks a person not doing stuff they might have otherwise - unless you say the plan already included you making your individual decisions (which makes it no plan). Sorry Evey that wasn't a rant at you - you were just my theological jumping off point

Consumer: Occams razor pulls me toward the mind being the source of the DMT experience, but to me that doesn't diminish the magicalness of it at all, considering that if you follow Kant (and neuroscience) the entire universe in any way we can know it is effectively in there to start with.
