>On LSD/mushrooms, you are more likely to curl up in a ball in the corner of the room crying than you are to experience euphoria. Nobody takes that stuff for "fun".

Consider that your social circle maybe just doesn't overlap the many people who do take this stuff for fun. As with alcohol, you just have to be careful. You wouldn't say 'On alcohol, you are more likely to curl up over the toilet crying and throwing up, or fighting a bouncer than you are to experience euphoria. Nobody drinks that stuff for "fun."'
