the idea of a "sitter" is someone that is not under the influence, so this could negate such effects if one fully follows the advice of the parent post Indeed. It's crucial advice. Doing LSD without a responsible sitter would be like riding a motorcycle without a helmet. It's very sad that LSD is both illegal and has a social stigma, because it's less likely that people will find LSD along with a responsible sitter. I'm a datapoint of one, but my experience was that people involved with getting LSD also tend to want to do it as a group. They're not very responsible. It's easy to imagine a friend trying to persuade you to do it with them, which is the situation I found myself in. But again, a datapoint of one isn't very useful.
