I found a way for atheists to find God, pagan gods or experience with higher beings. I did experiment with psychedelics while in college, but was rational enough to think I wasn't God. I did it to rebel, i.e. I do not believe what you are telling me about drugs, and expand my mind and not in a search for God (which was another experience completely). Thus, I didn't jump from a balcony even though I felt I could fly. It gives one a transcendent experience and a view at an alternative reality that lasts for about a twelve-hour period. I read Carlos Castaneda's A Separate Reality for class versus Moksha by Aldous Huxley to understand some of it. It is an en"lightening" experience.
Maybe Moksha is more relevant for today's generation.
Moksha
Disclaimer: I wouldn't recommend it to anyone over 40, but that's just my opinion. I guess it's best for the young to experiment with and one who is healthy and pretty well grounded mentally to begin with.
