Exactly, what weed does is make you *think* that everything you're saying or hearing is incredibly profound, so the subjective perception people have coming out of it is "wow, what a profound experience...". If they listened back to a recording, it would just sound, well, like the image here.
I used to watch a lot of people who smoked pot. It's true, none of them ever said anything thought-provoking. They were really good at Call of Duty though.
I’ve never heard a pot smoker say anything profound or thought provoking, ever.
