This is true, but I think it's important to not dismiss that maybe it just wasn't good for that person and they aren't going to get something positive out of it and it's not "their fault". And there are rare cases where people are permanently damaged by it. I have guilt from introducing a friend to it back in the day and he apparently did too much (either dosing or frequency) and was never the same again (in a bad way).
