While the one can lead to the other, they are obviously not at all the same thing. Both psychedelic drugs and religion have been credited with opening and closing minds. While drugs have killed people, many have been killed and died over religion too. Without knocking the sense of community and belonging that comes from many churches, I believe that when you must look to a priest, preacher, pastor, or guru to be your link to faith, much of your personal faith and individuality is undermined. While it certainly does depend on the particular individual in question, I believe this kind of faith forces you to look outward rather than inward, and to depend on another rather than yourself to keep your faith.
Faith is an interesting word.
It suggests the notion of belief without experience. While drugs perpetuate it through sensuous adventure and recreational risk, the Internet is perpetuating it with technological flare. The problem with drugs, aside from the fact that they can obviously kill you, is that they take you out of reality. You can never confirm any mystical or spiritual experience since you can't approach it with clear senses and thought. People who experiment with drugs may indeed be turning inward, but I believe they are doing it in the wrong way.
