Anyone experiences with psychedelics and meditation?

I know that the usage of drugs are a contradiction to the teachings the Buddha gave. But I wonder whether it could be helpful to use LSD or Psylocibin to gain profound insights. I read a lot about studies from the 50s to 70s, which starts again at the 90s, after a time of prohibition, that controlled usage of psychedelics have a profound meaningful impact on many participants of these studies who get an insight into egolesness which remains after the trip. Hmmm, does anyone have experiences with this combination or could recommend a paper / book related to this topic? The "idea": If it is possible due to Tantric practices to gain liberation in this life – maybe it could be even more achievable with the usage of LSD and Co. Thank you.
