I want to do it on the beach, I'm afraid of running into the ocean and drowning. What would you say is the probability of this scenario occurring for a first time trip?
If you're in the former camp (taking real acid), I have a truly hard time believing the anecdotes of bad things happening. And I think most anecdotes are actually stories from the latter camp. Just take a small dose and know that you can take the edge off with a beer if you really needed to.
But if you're in the latter camp where you don't even know what you're taking, I'm not particularly surprised if something bad happens.
I get a certain uncomfortable bodily sensation on LSD, to the point that after fifty or sixty experiences with it I no longer use it. I strongly prefer mushrooms and suggest mixing them with small amounts of MDMA for an incredible experience.
