If people here are seriously asking for evidence-based proof that acid can destroy people, then they are not very old or have survived partying / rave scenes.

The term "acid casualty" exists for a reason. I've known a few people that over-indulged and became detached weirdos and never came back.

It's not a 'wives tale' as someone here said. Take acid by all means. Just know that you could become a despondent ghoul if you go too hard and frequently.
