ok so.... laughing gas or N2O (Nitrous Oxide) is a sedative usually used by dentists for painful procedures. Yet every show I watch seems to think N2O... makes people laugh. It just sedates the person, making them numb to pain, and a bit lightheaded. The person won't fully know what's happening, but will have enough consciousness to be able to communicate, and do basic functions, like standing and walking. It helps calm anxiety, and you can see it's effects in any wisdom teeth removal video. It doesn't make you fucking laugh. Like either you watch too many cartoons, or you just don't know what Nitrous Oxide is. Or you're just dumb.
(sounds like my depression except for the anxiety part *laughs in depressed*)
