Yes.
Yeah, interesting stuff (nos not oxygen). Exactly, wouldn't say it made you 'euphoric', more like numb, like straight after a shot or two of absinthe (but without the feeling of 'ack, have I just swallowed burning petrol?').
Pretty scary though, I'm not doing that again (it was being sold at £3 a pop in a club, not a good plan methinks...)
Just as an interesting thingy, they use 50/50 nitrous oxide & oxygen for women giving birth, and it isn't tested for in blood (etc) tests -it disappears very quickly.
However it isn't great:
"Death can result if it is inhaled in such a way that too little oxygen is breathed in. While the pure gas is generally not toxic, long-term use in very large quantities has been
associated with vitamin B12 deficiency, anemia due to reduced hemopoiesis, neuropathy, tinnitus, and numbness in extremities. Harmful irreversible effects that may be caused by abuse of nitrous oxide include peripheral neuropathies and limb spasms.[2] Pregnant women should not use nitrous oxide as chronic use is teratogenic and foetotoxic. One study in rats found that long term exposure to high doses of nitrous oxide may lead to Olney's lesions.[3] Seizures, perception of time, and vision-altering perceptions are possible side effects."
Wow.. Oh the irony

Now, I (and all women) can't laugh cos' I've got one, and you can't laugh because you (being a man?) will probably have...errr, partaken in that activity before (unless you're a selfish lover which is no valid defence?), so by that logic only gay guys or virgin guys should be making rug jokes
Any more for any more?
