Definitely. Sam Harris' book Waking Up is what turned me on to psychedelics as a mind expanding tool rather than just a party drug, which I had little interest in.
In it, he talks about how his early experiences with psychedelics turned him on to the fact there was something real worth pursuing in meditation and mindfulness beyond the superstitious bullshit. Most of the book is about using meditation as a tool for spirituality without religious baggage or supernatural explanations.
The way he and others talk about it, is that psychedelics effectively force any mind into an objectively different state of consciousness. Even though it doesn't last long and the memory of it fades, just the awareness that radical mind shifts are possible is enough to help people take mindfulness practice seriously.
