yeh man laughing gas, N2O, they got the shit coming out of the walls in hospitals, right next to oxygen output, well in UK they do, its really easy to get aswell, is often used as a filler for whip cream cannisters, you ever heard of whippets? as Denis Leary sez 'You squeeze the nozzle just enough for some of the gas to come out, YOU snort that gas, and you are HIGH FOR FIIIIIIVE SECONDS, we didn't have MTV, no no, we had the fuckin' supermarket' or summat like that, but I don't recommend whippets, since the N2O is of a fairly low grade, and often contaminated with other, more harmful chemicals, but if you do any ecstasy pixel, I recommend it highly with E, it really kicks it up a notch, makes everything trippy as fuck, and the euphoria is next to nothing I've done before, my mate lay str8 down in the middle of the stairs with a balloon in his hand one time on pills and Nitrous, gurnin' his tits off . I also think with acid, shrooms or mescaline, the results would be similar, if not totally out of this fuckin world
